    [0002] Hydraulic component
    [0004] Object of the invention
    [0006] The present invention relates to a hydraulic component with a component housing and a connecting block.
    [0008] Previous technique
    [0010] Such hydraulic components are known from the prior art. The component housing generally has an outer surface and an axial hole, with at least one connecting channel extending from the outer surface to the axial hole. The connection block has a housing side with at least one connection hole, whereby the connection hole is in fluid connection with the at least one connection channel. The axial bore is configured so that pistons, such as sliding pistons or seat elements, can be displaceably arranged therein. These pistons are used to connect or block different channels, such as the connecting channel. Such hydraulic components can therefore be hydraulic valves.
    [0012] A problem with such hydraulic components is always the connection between the component housing and the connection block. Especially in high pressure hydraulic applications with pressures of several hundred bar, it must be ensured that the fluid connection between the connection port of the connection block and the connection channel of the component housing is tight.
    [0014] This is achieved, for example, by the fact that both the outer surface of the component housing in the area of the connection channel and the receiving side of the connection block in the area of the connection hole are largely flat and lie one over the other. This requires a high degree of precision in the production of the parts, which increases overall costs. This also sets limits with respect to the possible geometries of the component housing and the connection block. It must also be ensured that the clamping forces are high enough to ensure tightness. These high clamping forces can cause efforts within the pieces. To ensure that the particular axial bore is not affected by these loads, parts must be designed consistently strong, which in turn increases cost and weight.
    [0016] Therefore, the object of the present invention is to provide a hydraulic component that can be manufactured simply and inexpensively, whereby no loads occur in the component housing.
    [0018] The problem is solved by the features according to claim 1. Other preferred embodiments are described in the dependent claims.
    [0020] The hydraulic component according to the invention is characterized with respect to known hydraulic components in that the outer surface of the component housing has a non-planar shape, at least, in the area of the at least one connecting channel, and at least one connection bushing. connection with a through hole is received in the at least one connection channel and extends into the at least one connection hole.
    [0022] In other words, the outer surface in the area of the connection hole has a convex, concave, curved, rounded or even cylindrical shape seen in cross section. The connecting sleeve provides fluid connection between the connecting channel and the connecting hole and the outer surface does not need to lie flat on the housing side of the connecting block and strong clamping forces are not required. Due to the through hole of the connecting sleeve, a fluid connection can be established between the connecting channel and the connecting hole. Preferably, the through hole is a central hole that passes completely axially through the connecting sleeve.
    [0024] Preferably, the component housing has a substantially cylindrical shape. This means that the component holder can be manufactured particularly easily as a turned part. Here it is understood that a substantially cylindrical shape is a circular cylindrical shape, whereby certain deviations may exist, for example due to the connecting channel or receiving portions for clamping means or the like.
    [0026] Preferably, the housing side of the connection block has a substantially flat surface. This means that the connecting block can be manufactured particularly easily, for example as a machined cast part or as a milled part.
    [0027] Preferably, the at least one connection sleeve is axially movable with respect to the connection channel and the connection hole. Due to the axial mobility of the connecting sleeve, manufacturing related tolerances can be compensated to some extent, for example.
    [0029] Preferably, at least one first sealing member is disposed in a radial direction between an inner circumferential surface of the connecting channel and a first outer circumferential surface of the connecting sleeve. The first sealing member ensures that hydraulic fluid does not flow past the through hole and inadvertently exit the connecting channel.
    [0031] Preferably, at least one second sealing member is arranged in a radial direction between an inner peripheral surface of the connection hole and a second outer peripheral surface of the connection socket. The second sealing member ensures that the hydraulic fluid does not flow past the through hole and inadvertently exit the connection hole.
    [0033] In this regard, the first sealing member is preferably an O-ring. Furthermore, the second sealing member is preferably also an O-ring. O-rings are low-cost standard parts that allow good tightness. Furthermore, the O-rings also allow the connecting bushing to move axially with respect to the connecting channel and the connecting hole.
    [0035] Preferably, the component housing is received in at least one first clamp, at least one first clamp being attached to the connection block. The first clamp allows the component housing to be easily secured to the connecting block without excessive clamping forces causing loads on the component housing.
    [0037] In this regard, a gap is preferably provided between the outer surface of the component housing and the housing side of the connection block. The gap prevents the component housing from resting on the connection block due to manufacturing tolerances, which could place loads on the component housing.
    [0038] Preferably, the component housing has a first clamp portion and a first stop at a first axial end, whereby the first clamp is disposed on the first clamp portion and abuts against the first stop. This allows the clamp to be easily attached to the component housing in the desired position.
    [0040] Preferably, the hydraulic component has a second clamp attached to the connecting block, the component housing has a second clamp portion and a second stop at a second axial end, the second clamp being arranged on the second clamp portion and supporting the second stop. This ensures a particularly stable fixing of the component housing in the connection block. Furthermore, the axial position of the component housing relative to the connection block is also clearly defined.
    [0042] In the following, the invention is explained in more detail by means of an embodiment shown in the figures, in which schematically:
    [0044] - Figure 1 is a perspective view of a hydraulic component according to the invention;
    [0046] - figure 2 a top view of the hydraulic component shown in figure 1;
    [0048] - figure 3 a cross section along the line A-A shown in figure 2;
    [0050] - Figure 4 shows a side view of the hydraulic component shown in Figure 1;
    [0052] - figure 5 is an enlarged view of detail B shown in figure 4;
    [0054] - Figure 6 shows a perspective view of a component housing;
    [0056] - Figure 7 is a perspective view of a connection bushing; Y
    [0058] - Figure 8 is a perspective view of a connection block.
    [0059] Figures 1, 2 and 4 show a hydraulic component 1 according to the invention. The hydraulic component 1 has a component housing 2, which is fixed to a connection block 3 by means of a first clamp 17 and a second clamp 21. The component housing 2 is cylindrical in shape with an outer surface 4 and a hole central axial 5. In the exemplary embodiment, the axial bore 5 is configured to receive valve pistons (not shown). The connection block 3 has a housing side 7 with a flat surface to which the component housing 2 is attached.
    [0061] As shown in Figure 3 and Figure 6, the component housing 2 has at least one connecting channel 6, which extends from the outer surface 4 to the axial hole 5. In the exemplary embodiment shown, a total of three connection channels 6, the number of connection channels 6 depending on the intended functionality of the hydraulic component 1. As can be seen in particular in figure 6, the connection channels 6 are configured as stepped holes, each one for accommodating a connecting sleeve 9, which will be described in more detail below.
    [0063] The connection block 3 has at least one connection hole 8, which extends through the connection block 3 from the housing side 7, see figure 3 and figure 8 The number of connection holes 8 corresponds to the number of connection channels 6, so that in the exemplary embodiment a total of three connection holes 8 are provided. As shown in Figure 8, connection holes 8 are also configured as stepped holes to accommodate each of connection bushings 9. The connection holes 8 represent, for example, a P connection, a T connection and a consumer hydraulic connection.
    [0065] In each connection channel 6 a connection sleeve 9 is received. The respective connection sleeve 9 allows a fluid connection between the respective connection channel 6 and the respective connection port 8. Only one connection sleeve will be described below. connection 9, as shown in figure 7, so such explanations, of course, apply to all connection bushings 9.
    [0067] For the fluid connection, the connection bush 9 has a central through hole 10. To ensure tightness, a first sealing member 11 in the form of an O-ring is arranged in the radial direction between an inner peripheral surface 12 of the connection channel. 6 (see also Fig. 6) and a first outer peripheral surface 13 of the connection bush 9. A second sealing member 14 also in the form of an O-ring is arranged in the radial direction between an inner circumferential surface 15 of the connection hole 8 (see also Fig. 8) and a second outer circumferential surface 16 of the connection sleeve 9. When the connection sleeve 9 is received in the connection channel 6 and the connection hole 8 together with the first sealing member 11 and the second sealing member 14, a hermetic fluid connection is ensured between the axial hole 5 of the component housing 2 and the connection block 3, even though the outer surface 4 of the component housing 2 has a non-flat shape in the channel area connection 6. As shown in Figures 1 and 6, the component housing 2 is substantially cylindrical, so that the outer surface 4 in the area of the connection holes 6 has a cylindrical section shape, that is, it is curved or arched.
    [0069] To compensate for possible minor misalignments, for example due to the manufacturing process, the connection bushings 9 are axially movable relative to the respective connection channel 6 or the connection hole 8. The axial displacement of the respective connection bush 9 is limited by the respective step of the connection channel 6 or the connection hole 8. Due to the radial arrangement of the first sealing member 11 and the second sealing member 14, despite the axial mobility of the connection bushings 9 there is no deterioration of the tightness.
    [0071] As mentioned above, the component housing 2 is fixed to the connection block 3 by a first clamp 17 and a second clamp 21. For this purpose, a first clamp portion 19 is provided at a first axial end 18 of the housing. component 2. The first clamp portion 19 has a smaller diameter than the remaining outer surface 4, so that a first abutment 20 is formed between the first clamp portion 19 and the remaining outer surface 4, see also Figure 6. The The first clamp 17 is disposed on the first clamping portion 19 and abuts in the axial direction against the first stop 20. Correspondingly, a second clamp portion 23 is provided at a second axial end 22 of the component housing 2. The clamp portion The second 23 has the same diameter as the first clamp portion 19, which is therefore less than the diameter of the remaining outer surface 4. Po Therefore, between the second clamp portion 23 and the remaining outer surface 4 a second stop 24 is formed. The second clamp 21 is arranged on the second clamp portion 23 and abuts in the axial direction against the second stop 24.
    [0072] The first clamp 17 and the second clamp 21 are fixed to the connection block 3 by means of a plurality of clamping screws 25 - in this exemplary embodiment four clamping screws 25 are provided - by inserting the clamping screws 25 through corresponding holes through the clamps 17, 21 and screwing them into the corresponding fixing holes 27 of the connection block 3. Since the first Clamp 17 limits the axial displacement of the component housing 2 in one axial direction while the second clamp 21 limits the axial displacement of the component housing 2 in the other axial direction, the relative axial position of the component housing 2 and the connecting block 3 is fixed.
    [0074] As can also be seen in the enlarged representation shown in figure 5, when the component housing 2 is fixed to the connection block 3 by means of the clamps 17, 21, between the outer surface 4 of the component housing 2 and the side of the housing 7 of the connection block 3 a gap S. This gap S avoids loads when fixing the component housing 2 in the connection block 3, since there is no direct contact between the component housing 2 and the connection block 3. A possible misalignment is compensated for by means of the axial mobility of the respective connection sleeve 9.
    [0076] As can be seen in particular in figure 6, the component housing 2 has a substantially cylindrical shape, so that the component housing 2 can be cost-effectively manufactured as a turned part. Only the connecting channels 6 and the recesses 26 "interrupt" the cylindrical shape. In this exemplary embodiment, the recesses 26 serve to facilitate installation by allowing set screws (not shown) to pass. Of course, these recesses can be omitted if an alternative mounting is considered.
