    [0006]
    [0007] A dry clutch consists of two clutch halves, namely, the housing element or female part, as well as a corresponding connector or male part. For example, the housing element is connected to a fuel hose line, while the connector forms a connection in a tank. A generic dry clutch has a typical construction and function. Each clutch half comprises a valve with a valve body that can change position axially to open and close the corresponding valve. In the coupled state of the two clutch halves, both valve bodies are in a valve assembly that can be repositioned axially by the rotary movement of a housing control element, provided with a Stephenson type guide distribution. , of the housing element to open and close the valves. At least the valve body of the connector is subjected to recovery force. Especially the dry clutch and its components have standardized features according to NATO standardization agreements (STANAG).
    [0008]
    [0009] A known dry clutch housing element has, in accordance with DE 102012 209 629 A1, a locking device with a locking anchor pin which is radially received in perpendicular to the axis of the housing element and acts against an axial peripheral running surface of a guide edge. The locking anchor pin is engaged by articulation by a two-arm drive lever. The hand control of the drive lever is laborious, especially when connected to a housing handle. The locking anchor pin penetrates with its foot, only partially, into a locking anchor point. Reliable maintenance of the anchorage connection is reliably affected and the joint is susceptible to wear. DE 858617 discloses a dry clutch housing element with a locking device comprising a locking anchor pin housed so that it is axially parallel in an inner clutch housing. A drive device has a drive lever engaged by articulation about an axially parallel axis, which lever can only be placed in two adjustment positions, namely in a locking position of the anchor pin in a locking hole, as well as in a locking position. in a position that releases the anchor pin from the locking hole.
    [0010]
    [0011] The invention is based on the objective of improving the locking device in terms of its ergonomic handling and a more secure locking function.
    [0012]
    [0013] The objective is achieved, in conjunction with the features mentioned at the beginning, because the anchor element foot is oriented parallel to the accommodation element axis, because the guide running surface is formed by a radial front surface of the guide edge and in that the actuating lever is a lever with an arm, the pivoting actuating shaft being, which couples the lever by articulation in an arm, oriented transversely with respect to the axis of the housing element and the drive connection being arranged between the pivoting axis lever and a free end, for the drive, of the drive lever.
    [0014]
    [0015] The dry clutch housing element according to the invention also determines a dry clutch for fluid according to the invention which is formed by the dry clutch housing element and a dry clutch connector connected thereto, presenting the dry clutch connector a connector valve with a connector valve body that forms, together with the housing member valve body, a sliding joint that can be repositioned axially that can be placed, against the force of recovery , from valve closing positions corresponding to valve opening positions. Advantageously, the dry clutch connector can have a peripheral connection groove which can engage without engagement, in the peripheral direction, the connection elements of the dry clutch housing element.
    [0016]
    [0017] The indication "axially" is understood respectively, in the context, as parallel to or in the direction of the central axis of the housing element housing (housing element axis) or an axis coaxial with the housing element axis. The indication "axially" refers especially to parts or surfaces extending in the axial direction and in which the axis of the housing element or an axis coaxial with it is located. The indication "radially" refers to directions starting from a corresponding axis and are oriented perpendicularly to this axis, or refers to parts or surfaces that extend perpendicularly or radially in relation to a central axis.
    [0018]
    [0019] The configuration, according to the invention, of the locking device is linked with special advantages. Especially, with the coupling by articulation of the lever of an arm and the arrangement of the attachment of the driver, it is achieved that the free end of the actuating lever on the perimeter of the accommodation element housing coincides in a timely access area Under the economical point of view. The actuating lever can be advantageously arranged in a position of pronounced inclination with respect to the axis of the receiving element with, preferably, an angle of at least almost 90 ° or in the range of 90 ° ± 30 °. In addition, the anchor element foot operates in the optimal position against the guide running surface. This improves the rolling behavior of the anchor pin by blocking, as well as its hooking at the anchor point by blocking. In each position of the drive lever, the anchor element foot is pressed against the guide edge.
    [0020]
    [0021] The anchoring element can be adjusted linearly, parallel to the axis, between the release position, in which the anchor element foot fits the guide tread, and at least one anchor / lock position by means of the sliding bearing. The drive link transforms the pivoting movement of the drive lever into the movement parallel to the axis of the anchoring element. Conveniently, the arm operating lever can pivot about the pivot axis perpendicular to the housing element axis. The compression force device advantageously comprises a spring element that generates recovery force.
    [0022]
    [0023] Advantageously, a particularly effective locking locking connection can be formed between the locking engagement point and the anchoring element foot, which is determined by complementary anchoring surfaces with the same shape. Advantageously, the locking anchor point is formed by a locking anchor cavity. This is advantageously configured as an orifice-like cavity with a bottom contact surface such that the anchor element foot in the blocking position also reaches its seat contact surface with a form-fitting seat. same way.
    [0024] Particularly preferably, the sliding housing of the anchoring element is oriented such that the adjustment movement, parallel to the axis, of the anchoring element along the peripheral running path in the release position and in the blocking position it is limited only by the impact of the contact surface standing against the guide running surface, as well as against a bottom of the anchor point by blocking.
    [0025] According to a configuration, the housing member housing is provided, partially and preferably in its entirety, as an outer housing in which the sliding bearing is arranged to receive the anchoring element. According to a configuration, the housing element housing is provided separately from the control sleeve. The housing member housing and the control sleeve then form two separate components which are rigidly connected to one another by means of a form-fit connection. A preferred configuration consists in that the anchor element sliding bearing is configured with a compression force device acting directly on the anchoring element. The actuating lever is released from a load with compressive force to tighten the anchor element foot against the guide running surface.
    [0026] In a preferred configuration the locking anchoring element is formed by a locking anchor pin housed with its pin axis parallel to the housing element axis. In a particularly advantageous manner, the locking anchor pin can be housed so that it can rotate about its pin axis by means of the sliding bearing, as well as the drive link, the contact surface touching the contact surface standing only partially, especially only in the area between the pin shaft and the foot edge, closer to the axis of the housing element, of the anchor pin by blocking. With this form of contact, the anchor pin enters into rotation. A rolling with particularly low wear of the anchor pin by blocking on the guide running surface is achieved.
    [0027] According to the invention, the pivoting lever axis of the arm operating lever can be arranged adjacent to the area or in the area of the wall of the housing element housing. Especially advantageous is an arrangement of the pivoting lever axis such that it cuts off a cylinder cross-section, preferably as small as possible, of the housing element housing as a drier. The pivoting point of the drive lever can be moved towards the housing element axis. As a result, the one-arm drive lever is oriented at a certain angle and relatively long on the outer side of the housing element housing. Especially in combination with this combination of this pivoting lever axis arrangement, a particularly advantageous configuration consists in that the drive connection is spaced, with a short lever section, from the pivoting lever axis and, with a lever section, by the relatively long opposite of the free end of the drive lever. A particularly small short lever section is reached because parts that engage by articulation of a flat lever are located under the apex of the housing member housing and the driver attachment is provided in the area of the housing zenith. Advantageously, the edge of the housing side of a drive plate is adapted to the shape of the housing element housing between two bearing points of the pivoting bearing, especially in the zenith zone.
    [0028] The locking device according to the invention forms, with a housing handle of the clutch housing element, an especially suitable ergonomic arrangement which allows one-handed operation. The actuating lever is provided as an element that can be operated by hand, with the free lever end reaching the inside of the area of at least one finger of a hand that catches the housing handle. The housing handle, which, with a subject guide seat ring, is adjusted to rotate the housing element housing together with the control sleeve around the housing element axis, is radially spaced from the element housing. accommodation.
    [0029] Advantageously, the housing handle is provided as a wing-like handle with a handle loop that covers a peripheral section of the housing element housing, with the actuating lever disposed preferably in the middle between the handle loop and the housing of accommodation element. A particularly preferred configuration consists in that the actuating lever is formed by a handling plate that extends between two handle arms that connect the handle loop. Advantageously, the pivoting bearing that joins the drive lever can be configured in the region of points where the handle arms are connected to the housing element housing. Advantageously, the actuating lever or the actuating plate can be coupled by articulation on the handle arms, preferably at the ends of the handle handle. Especially with this arrangement the pivoting lever axis can be deposited inside the cross-sectional area of the control sleeve. With a pivoting lever axis which is located deeply in this way, the drive connection can also be deposited in a particularly deep manner up to the level of the outer perimeter of the control sleeve or of a specially narrow section of the housing element housing.
    [0030] Conveniently, the fastening ends of the housing handle in the region of the guide seat ring can be fixed to the housing element housing.
    [0031] Advantageously, the actuating device can be provided with an electrically activatable adjusting element. The locking anchoring element according to the invention can be particularly easily connected to an adjusting element which is conveniently arranged in the area of the drive connection in the housing element housing. Advantageously, the adjustment element is oriented so that the anchoring element can be fixed in a defined manner by controlling the adjustment element with electrical control signals in the locked position and can be released to unlock, as well as to produce the state of release.
    [0032] The locking device according to the invention is such that desired initial, intermediate and / or end positions of the anchoring element can be adjusted on the guide running surface. In particular, several anchor points can be configured per block. One configuration consists in that the Stephenson type distribution of the guide of the accommodation element control device has at least one control curve with a control curve anchor point, which is assigned to the opening position of the control element. valve housing element and part of the aforementioned a blocking position of the anchoring element by blocking. An advantageous configuration also consists in that the Stephenson-type guide arrangement of the accommodation element control device has at least one Stephenson type axial distribution opening, which opening is open on one side directed to the guide seat ring for insertion a control element mentioned in a direction parallel to the axis y is assigned to a position for blocking the guide running path.
    [0033] The initial position of the peripheral running path is determined in particular by the closing position of the housing element valve. At least one control element of the control device is thus located at the closed end of a Stephenson-type distribution rail of the Stephenson type guide distribution, the closed end being opposite the end of the front side of the control sleeve. Especially the initial position is not assigned any blocking position.
    [0034] The secondary claims are oriented toward the mentioned configurations of the invention and even towards other convenient and advantageous ones. Only particularly advantageous and advantageous forms and configuration possibilities are explained in more detail by the following description of the exemplary embodiments shown in the schematic drawing. Each individual or detailed configuration described within an exemplary embodiment should be understood as a structurally independent detailed example for other embodiments and configurations not described or not fully described as forming part of the invention. Then, especially with the indication "in general", such characteristic is indicated and understood that, isolated from other characteristics of one or several embodiments, it contributes to the achievement according to the invention of the general theory of the invention.

    [0045] From FIG. 1A through FIG. 2B a dry clutch housing element 6 according to the invention is shown in the position and mounting arrangement in a dry clutch 100 as well as separated from it. A valve device 1 of the housing element 6 is provided with a valve body 3 for receiving element. The valve device 1 forms, in the exemplary embodiment, a self-contained modular element of the housing element 6, namely a physical valve unit also indicated by reference 1.
    [0046] The dry clutch 100, shown in the coupled state in FIGS. 1A and 1B, has the receiving element 6 (female part) and a connector 7 (male part) forming clutch halves. The housing element 6 and the connector 7 are coupled to one another in the region of a clutch cutting point 110. A housing element shaft 60 and a connector shaft 70 coincide on a clutch shaft 101. In the coupling state, at the cutting point 110, the housing member valve body 3, which is a component, is located adjacent to each other. of a housing member valve 4, and a connector valve body 751 of a connector valve 75, being in a sliding joint that can change its position on the clutch shaft 101. The connector valve body 751 is accommodated so that it can be moved axially by sliding in a connector housing 71 against the spring force of a compression force device 76. The valve body 3 is housed within a tubular casing housing 61 and can be moved. with translation to defined positions in axial direction. A housing element control device 5 converts a rotational movement of the housing member housing 61 about the clutch shaft 101 in the defined translation movement. Casing handles 67 for the rotation adjustment are placed in housing housing housing 61.
    [0047]
    [0048] In Figure 1A the valve bodies 3, 751 are in closing positions 401, 701 of the valves 4 and 75. Consequently, the passage of fluid is blocked. The valve body 3 has a valve head 31 which, with the valve housing element 4 closed, penetrates a valve seat 41 of the receiving element. At the cutting point 110 the connector valve body 751 enters correspondingly into a connector valve seat 77. In the closing state of the valves 4, 75 according to FIG. 1A, the clutch halves can be separated from each other by releasing the connecting elements 66, 73 that join them.
    [0049]
    [0050] Also starting from the coupling state according to Fig. 1A, the valves 4, 75 can be opened to drive fluid through the dry clutch 100. As a consequence of a defined rotation adjustment of a control sleeve 51 of the control device of housing element 5, which device is rigidly connected to the housing element housing 61 by torsion, the valve body 3 changes its position axially, so that the valve head 31 leaves the valve seat 41 in a position opening valve 402 of housing member and axially displacing connector valve body 751, against the spring force of compression force device 76, to an opening position of connector valve 702. By means of the control device 5 the position of the sliding connection is defined and maintained to open the valves 4, 75. This state is shown in FIG. 1B. To close the valves 4, 75, the valve slide joint is repositioned in the position of Figure 1A by a reverse rotation adjustment of the control sleeve 51 and with the force of the compression force device 76.
    [0051]
    [0052] A protective sleeve 613 is placed on the first housing end 611 of the housing member housing 61. Conventional sealing elements are disposed respectively between the parts of the valves 4, 75 and the other parts of the two clutch halves.
    [0053]
    [0054] The dry clutch housing element 6 is shown in more detail in FIGS. 2A and 2B. In FIG. 2A, the housing element valve 4 is in the closed state 401, whereas in FIG. opening position 402. The housing element 6 is generally composed, in a modular manner, of the housing element housing 61, the control sleeve 51 and the physical valve unit 1.
    [0055]
    [0056] The sides, ends and end areas of axially extending components, which are directed to the coupling side of the dry clutch housing member 6 or are located in the area of the coupling side are described with "front side" or "front side", while the ends, sides or areas that are opposite are marked with "back side" or "back side".
    [0057]
    [0058] The housing element housing 61 generally forms a pressure housing with connecting / joining elements for coupling. The first (front) housing end 611 on the front side of the housing element housing 61 is adjusted for coupling with the dry clutch connector 7. A second housing end 612 (rear) on the rear end face of the housing element housing 61 is adapted for connection with a conduit or hose element (not shown). In the exemplary embodiment, the housing element housing 61 is equipped with a rotating articulated part 63 which is rotatably mounted around the axis of the housing element 60, at the housing end 612 of the rear side by means of a rotary joint. of ball bearing 630 and is adjusted for connection to a conduction. At the front housing end 611, connection elements 66 are disposed, in particular connecting or separating rollers 661 that can be placed on the connecting element 73, in particular in a peripheral connection slot of the connector 7, for the connection with the connector of clutch 7. A flange edge of the connector 7 has a connection cavity 74 through which the connection elements 66 are placed for coupling and uncoupling and, in the coupling state, are retained in the connection slot by the adjustment of rotation of the housing element housing 61. The placement and assignment are especially detached from Figure 3.
    [0059]
    [0060] In the exemplary embodiment, the control sleeve 51 of the control device 5 is a separate component that does not form any component of a pressure housing. The control sleeve 51 has an outer sleeve diameter which corresponds to an inner diameter of the housing member housing 61, such that between the housing element housing 61 and the control sleeve 51 a peripheral groove 58 remains. which ensures that the control sleeve 51 can be placed freely or with smooth rolling in the housing element housing 61. The control sleeve 51 is inserted concentrically into the housing element housing 61, and can be introduced, as can be seen from FIGS. 2A and 2B, at the rear housing end 612, in the housing element housing 61. A connector is formed by form-fitting 8 without thread, without grip, without pin and without pressure which accommodates the sleeve control 51 is accurately centered in the housing element housing 61, which produces a rigid torsional connection with the housing and housing element 61 a with defined rotation displacement and accommodates the control sleeve 51 at its two front ends axially in the direction of the housing end 611 on the coupling side against radial stops. The control sleeve 51 is fixed on its rear side by a safety element 89 in the form of a safety ring housed in the inner wall 610 of the housing element housing 61, safety ring that must be placed and removed from the housing. easy way The invention is not limited to this connection. The control sleeve and the housing element housing can be unit, for example, rigidly torsionally, with other elements or be together to form a one-piece body.
    [0061]
    [0062] The measurement of the rotational adjustment of the control sleeve 51 which can be rotated together with the housing element housing 61 around the housing element axis 60, as well as of the translational elevation, caused thereby, of the valve body 3 is determined by a Stephenson type layout of guide 53 with two control curves 530. As can be seen from Figs. 4A, 4B, the two control curves 530 are arranged offset in the peripheral distance of 180 °, extending from the same shape and with the same orientation, from one end of the control curve 56 inside closed in the shape of a helix to an open external control curve end 57. The outer open control curve 57 ends are open axially, with Stephenson type distribution openings 531, on the front side of the control sleeve 51 directed to the first housing end 611. The axial length of the control sleeve 51 is calculated from such that to the front side of the control sleeve 51 a guide seat ring 2 is connected with interposition of a seat ring spring element 65 and has its place in the housing element housing 61. The seat ring guide 2 and control sleeve 51 form the inner wall of a fluid passage space 62. An inner wall 510 of the control sleeve 51 and an inner wall of seat ring 21 advantageously have an internal diameter ID common.
    [0063]
    [0064] The control device 5 further has control elements 55, for example, in the form of control heads formed by control rollers 551, control heads which are generally arranged in a rear part of the valve body 3 and are inserted into the control curves 530. Conveniently, the Stephenson-type guide distribution 53 forms a guide that causes the maximum elevation of the valve body 3 as a consequence of a rotation adjustment of the control sleeve 51 of at least 90 °, preferably of 100 ° up to approximately 120 °. In the exemplary embodiment, control rollers 551 may be placed on radial ends of a foot transverse member 320 of the valve foot 32. A radial through hole 325 is incorporated in the foot transverse member 320 which is adjusted to receive support bolts. 552 of the control rollers 551. The roller support bolts 552 can be detachably incorporated in through holes of the perforation 325 opposite around 180 °.
    [0065]
    [0066] The valve body 3, the control sleeve 51 and the guide seat ring 2 have corresponding central body shafts 30, 50 and 20 which are coaxial with the housing element shaft 60. The housing element housing 61, the control sleeve 51, the guide seat ring 2 and the valve head 31 are cylinder parts or sections with circular cross sections.
    [0067]
    [0068] As can be seen in particular from FIG. 3, three connection elements 28 protruding from the front side in the form of cams are configured at the end of the seat ring 23 with a peripheral distance of 120 °. the three housing connection elements 66 are assigned. The connecting elements 28 are formed on a peripheral outer edge 29, on the front side, of the guide seat ring 2. The assignment and arrangement are such that the connection elements 28 of the seat ring and the connecting elements 66 of the housing are axially aligned with one another for the coupling and separation of the clutch halves. In FIG. 3, only one axial alignment plane FA is shown. It is noted that the seat ring connection elements 28 penetrate into the connector connection cavities 74 when the clutch halves are coupled to one another. With this, the guide seat ring 2 can be placed, for the coupling and during the coupling, in a locking position blocking the relative rotation between the guide seat ring 2 and the connector housing 71. In the case of a retained guide seat ring 2, the housing element housing 61 can rotate about the guide seat ring 2 for coupling, the decoupling and axial displacement with translation of the valve body 3 between an initial position and a final position, as described even more in detail especially by means of figures 1A, 1b and 9B.
    [0069]
    [0070] Generally, with a defined angular position of rotation displacement between the housing member housing 61 and the control sleeve 51, 53 Stephenson-type guide distribution positions (initial positions) of the joints are set and determined in the Stephenson type layout. connecting elements 28, 66 assigned to the valve closing position 401, as well as final positions of the control elements 55 assigned to the valve opening position 402. In the exemplary embodiment, the connecting elements 28, 66 form, in their mating connection positions, three pairs of terminals in which the connecting elements 28, 66 are aligned axially with one another (FIG. 3). As can be seen in particular from FIGS. 1A, 2A, the guide seat ring 2 in the housing member housing 61 is held between the connecting elements 66 and the seat ring spring element 65. The rotational displacement defined between the housing element housing 61 and the control sleeve 51 is chosen so that the control elements 55 penetrate, correspondingly to the coupling connection positions for coupling and decoupling the two halves of the coupling. dry clutch clutch 100, at anchor points 560 of control curve at the inner ends of control curve 56. The control elements 55 that should be observed in Figure 3 are in this position. The control sleeve 51 is not shown in Figure 3.
    [0071]
    [0072] The valve device 1, as shown in FIGS. 5A, 5B, is a prefabricated component. The valve device 1 generally comprises the guide seat ring 2 with the inner seat ring wall 21 and the valve body 3. The valve body 3 comprises the valve head 31, a valve foot 32, as well as the valve body 31. a ribbed part of valve 33 connecting the valve head 31 and the valve foot 32 with one another and distance them axially. A radial guide bearing 25 accommodates the ribbed portion of valve 33 on the inner wall of the seat ring 21 in such a way that the valve body 3 can be moved axially by sliding along a central axis of body 10 of the unit Valve physics 1 to get to the adjustment movement with translation. The valve seat 41 is formed on a first, front end of the seat ring 23. Corresponding support elements 26, 34 are formed by pairs of support elements respectively having, on the interior wall of the seat ring 21, a nose-shaped support element 260 with a U-shaped cavity and in the valve rib portion 33, a rail-like support element 340. The two pairs of support elements are arranged at a peripheral distance of 180 °. In a bearing seat housing plane LA forming part of a bearing seat, there coincides an axial bearing plane of the seat ring SA, in which the nose-shaped support elements 260 are placed, and a housing plane axial valve body VA, in which the rail-like support elements 340 are located. The foot cross member 320 is arranged and oriented, like the ribbed portion 33, in the bearing seat housing plane LA of the rail-like support elements 340, and has a transverse foot diameter DF which is greater than an inner diameter of bearing DL which is determined by the diagonal axial free distance of the first supporting elements 260. In the exemplary embodiment also a radial transverse diameter DS of the ribbed part of valve 33 is equal to the transverse foot diameter DF.
    [0073]
    [0074] For assembly with control elements placed on the valve foot 32, the physical valve unit 1 is inserted into the housing element housing 61, the control elements 55 being able to be introduced in the axial direction into the axial distribution openings Stephenson type 531. In this process, the outer edge 29 of the guide seat ring 2 must pass through the housing connection elements 66. In the embodiment, this is achieved because three edge cavities are incorporated in the outer edge 29. 27 which are assigned to the seat ring connecting elements 28. The edge cavities 27 are located at a peripheral distance, from the connecting elements, which corresponds to the peripheral distance of the Stephenson 531 axial distribution openings. of the control curve anchor points 570.
    [0075]
    [0076] As can be seen from FIGS. 3, 5A and 5B, a key connection of the radial guide bearing 25 is fitted between the nose-shaped support elements 260 and the rail-like support elements 340. For assembly and disassembly of the physical valve unit 1 by means of relative rotation adjustment and axial adjustment, mounting cavities 35 can be placed between the guide seat ring 2 and the valve body 3 with the corresponding support elements 260 , generally with the same shape, with a nose shape in matching assembly free positions. In these positions a radial plane SR, in which the first support elements 26, and a radial plane VR, in which the mounting cavities 35 lie are located. The dimensioning of the valve rib portion 33 is in a form that the axial elevation which is provided for the opening of the valve housing element 4 is less than the maximum distance between the radial planes SR, VR (FIG. 5B). In the course of the mounting positions, the nose-shaped support elements 260 with the U-shaped cavities and the rail-like support elements 340 can be arranged axially in a bearing overlap connection or can be removed this.
    [0077]
    [0078] The dry clutch housing element 6 is provided with a locking device 9 according to the invention with which the guide seat ring 2 in the housing member housing 61 is fixed in a rotational position in which the housing element valve 4 is open. This opening rotation position is detached from the cut view according to Figures 1B and 2B.
    [0079] The locking device 9 comprises a locking anchoring element 91 housed in the housing element housing 61 in the form of an anchor bolt or an anchor bolt 911, as shown in FIGS. 1A, 2A, FIGS. 6A , 6B, FIGS. 7A, 7B and FIG. 8. A sliding bearing 95 is disposed in the housing member housing 61. A bearing housing 951 has a bearing bearing bushing 952 that houses the anchor bolt by blocking 911 so that it can be moved with movement from one side to the other parallel to the housing element axis 60. The bearing bush 951 further forms a spring chamber housing of a compression force device 96 with a compression spring. 961 which applies compression force on the anchoring element 91. The anchoring pin 911 has an anchor element foot 93 with a foot contact surface 930 on the bottom side and a anchor element head 913. The compression force device 96 presses the foot contact surface 930, with a restoring force, against a guide running surface 900 of a radial guide edge 92 that is configured at the edge exterior 29 of seat ring. The guide running surface 900 is a radial front surface opposite the front side of the guide seat ring 2, a front surface which is formed along a peripheral running path 90 by a circular ring section (Figures 9A, 9B ). The guide running surface 900 is oriented flat and perpendicular to the receiving shaft 60. Conveniently, the leading edge 92 is configured with a front surface 921, which forms the running surface 900 in a section, peripherally in the guide seat ring 2. The foot contact surface 930 has, at least essentially, a surface parallel to the guide running surface 900.
    [0080]
    [0081] In the exemplary embodiment, the anchor pin 911 can be moved between a first position, namely an initial position 901 of the peripheral running path, and a second position, namely an end position of the peripheral running path 90. In FIG. finds the anchor pin 911 in the starting / initial position 901, which is defined because the control elements 55 penetrate so that they are anchored at the control curve anchor points 560 at the inner ends of control curve 56, that is, by the position of the valve body 3 in which the valve housing element 4 is closed and the housing element 6 is in the state to be coupled or uncoupled.
    [0082]
    [0083] The running path of the anchor pin 911 is approximately 110 °. The second anchor pin position in the locking position 902 at the end of the running path 90 can be seen from Figure 9B. The angle of rotation or the length of the running path 90 from the initial position 901 to the blocking position 902 are determined by the rotation adjustment experienced by the control sleeve 51 between said coupling / uncoupling position housing 4 closed) and a defined opening position of the housing element valve 4. In the exemplary embodiment the valve opening position is defined because the control elements 55 penetrate the anchor points 570 of the control curves 530
    [0084]
    [0085] For blocking in the blocking position 902, the anchoring element foot 912 and a locking anchor point 94 directed to the end of the rolling path are specially designed and adapted to one another. An anchor point 94 is formed by an anchoring cavity 941 which is incorporated, parallel to the axis, in the guide edge 92 and is formed by a hole in the shape of a circular cylinder with a bottom. The anchoring element foot 93 is formed, with its foot contact surface 930, so that it is placed in the anchoring cavity 941 in a complementary manner, with the same shape on all sides, by form dragging. The anchor element foot 93 is released from the locking seat by linear displacement of the anchor pin 911 against a compression / recovery force. The installation, which is under compression / recovery force, of the anchor pin 911 against the running surface 900 defines, in addition to the anchor point 94 by blocking, a dismounting position of the anchor pin 911.
    [0086]
    [0087] Another particularly advantageous measure consists, as in the exemplary embodiment shown, in that the anchor element foot 93, in its running path between the position 901 and the position 902, can be moved, with a rotational movement, around to its pin shaft 910. The anchor pin 911 is housed by the sliding bearing 95 so that it can move with rotation about its pin shaft 910. The guide running surface 900 of the guide edge 92 is configured and dimensioned such that it only touches an edge area of the foot contact surface 930. This contact of the anchor element foot 93 in the area between the pin shaft 910 and the foot edge, closest to the element axis of accommodation 60, of the locking pin 911 is shown in FIGS. 6B and 9A, 9B. The contact surface 930 of the anchoring element foot 93 reaches a maximum of half the installation on the guide running surface 900. This results in the anchor pin 911 rotating about its pin axis 910 when moving in its running path 90 between positions 901 and 902. The foot contact surface 930 is adjusted, at each rotational position of the anchor pin 911, with the compressive force uniformly against the running surface of 900 guide.
    [0088]
    [0089] According to the invention, a special drive device 97 is configured to drive the anchor pin 911. The drive device 97 comprises a drive element in the form of a drive lever 971 of an arm which is engaged by articulation in an arm by means of a pivoting bearing 98 about a pivoting lever axis 980 which is oriented perpendicularly to the housing member axis 60. Advantageously a free end of the actuating lever 971 extends in the area of a housing handle 67 disposed in the housing element housing 61.
    [0090]
    [0091] Between the pivoting lever axis 980 and a free end, for the actuation, of the actuating lever 971, a drive connection 99 is configured in such a way that the anchoring element 91, depending on the pivoting positions of the actuating lever 971 , is in the dismantling position and in the locking position 902. In the area of the anchor element head 913 the anchor pin 911 has a driver slot 991 into which the trailing edge 992 of an orifice penetrates. elongate which is configured in the drive element 971 near the pivot bearing 98 (FIG. 7B), ie, the drive link 99 is spaced apart, with a short lever section, from the pivoting lever axis 980. On the contrary, the free lever end for actuating the arm lever 971 is at a relatively large distance from the drive link 99. Each drive link can be provided with and apply the movements between the actuating lever 971 and the locking pin 911.
    [0092]
    [0093] A special configuration shown in more detail in FIGS. 7B and 8 consists in that the pivoting bearing 98 has two bearing balls 981, the actuating lever 971 being in the form of a handling plate, coupled by articulation, in the region from side edges of plate at the bearing end, by bearing bushes 982, to the bearing balls 981. The bearing balls 981 are fixed by threaded connection 983 to inner ends of fixing of radial grip arms 672 of the housing handle 67. The inner ends of gripper arms are fixed with threaded connection 674 to housing consoles 673 below a zenith of a wall 614 of the housing element housing (Figures 8, 9A, 9B). As can be seen in particular from FIGS. 8, 9A, 9B, the pivot shaft 980 cuts off the cross section of the housing element housing 61 in the smallest diameter region of this housing as a secant. Generally the pivot shaft 980 is located, in the cross-section of the housing element housing, especially deep to the inside of the cross-sectional area of the control sleeve 51. Furthermore, the driver attachment 99 is spaced apart from the pivoting bearing 98. , in essence with only one dimension of this bearing, in the exemplary embodiment, approximately half the diameter of the bearing balls 981 or of the bearing bushes 982. The ends of the grip arms are fixed, in the region of the guide seat ring 2, to the housing element housing 61. The operating plate is adapted, with an inner concave edge, to the outer contour of the housing element housing between the bearing bushes 982.
    [0094]
    [0095] The actuating plate forms a kind of connecting bridge which, arranged in the middle in the access area of the housing handle 67, extends under the bar 671, as can be seen in particular from FIG. 8. The operating lever 971 in the form of the plate-like handling zone it extends with the bar 671, so that it is located in the access area of the fingers of a hand that takes the housing handle 67 and is disposed and can be used according to the type of change in the steering wheel. Generally the actuating lever 971 is oriented with a pronounced inclination towards the axis of the receiving element 60. In the exemplary embodiment according to FIGS. 7A, 7B, the angle S between the axis of the receiving element 60 and the operating lever 971 is almost 90 °. This lever position forms part of the initial positions 901 of the locking anchor pin 911 shown in FIGS. 8 and 9A. In the blocking position (Figure 9B) the angle S is 90 ° or somewhat larger.
    [0096]
    [0097] The locking device 9 is driven and connected in a simple manner by the pivoting movement of the actuating lever 971 about the pivot axis 980. In the initial position 901 and during the movement along the running path 90, the surface of counted standing 930 fits the guide running surface 900, and the anchor element foot 93 reaches, at the locking anchor point 94, the locking position 902. This anchoring / locking position is clearly appreciated by an operator upon reaching it, and in addition the coupling state is secured in the open position of the housing element valve 4. This assurance is made in addition to the anchorage securing that is produced by the anchoring seat of the elements control 55 in the control curve anchor points 570.
    [0098]
    [0099] To close the valve housing element 4 or for decoupling, the anchor pin 911 can be released comfortably, against the restoring force, from the shape dragging in the locking anchor cavity 941 by means of the actuating lever 971 pivoting / can be moved to position 901 in the disassembly position by the described rolling path.
    [0100]
    [0101] The position 901, which represents the starting position for coupling or uncoupling with the closed housing element valve 4, can be configured, if necessary, with a locking anchor point which corresponds to the anchor point 94 by blocking described. Otherwise, the one or more anchoring points can define other desired running paths or at least one intermediate position in a running path of the locking anchor element 91 and be provided with the blockage according to the invention.
    [0102] In FIG. 8, an actuator 975 disposed in the housing element housing 61 is shown only with dots and dashes, which drive is generally equipped with the locking anchoring element 91 to block and release the axial movement of the anchoring element 91 and It can be put in this operating state with a control by electrical signal. This or another drive that can be controlled electrically can also be adjusted so that the locking anchor element is unlocked by axial movement of adjustment by means of the drive.
