    A rotary distributor fuel injection pumping apparatus has a rotary distributor member rotatable within a sleeve forming part of the body of the pumping apparatus. The distributor member includes a transverse bore which carries plungers movable inwardly by cam surfaces on a cam ring, as the distributor member rotates. The distributor member is movable axially in the body to vary the amount the plungers can move outwardly and therefore the amount of fuel delivered by the apparatus. The extent of outward movement is determined by complementary inclined surfaces formed on cam followers associated with the plungers and a part rotatable with the distributor member but axially fixed in the body.

    The invention relates to mechanical engineering, more specifically to twin-engine construction, namely, to the fuel injection equipment of internal combustion engines, and can be used in pumping devices of distribution type.
    A pumping device for injecting liquid fuel into the cylinders of an internal combustion engine is known, comprising a housing mounted in the housing with the possibility of synchronous rotation and connected to the engine through a clutch assembly and a drive shaft distributor having a transverse channel in which plungers are located and an axial passage communicating alternately during rotation of the distributor, an interplunger cavity with an inlet line or a discharge line, located around the distributor in the zone of the transverse channel, an annular cam washer with internal working profile, pusher consisting of a shoe located at the piston end of the plunger, and a roller coupled to the working profile of the cam washer, suction stroke limiter of the plungers, including adjoining additional inclined surfaces on the pushrod pads and on the stop located around the distributor in the zone of the transverse channel, and the control mechanism 1.
    In the known device, the suction stroke limiter of the plunger rotates together with the drive shaft, and to adjust the suction stroke of the plungers it is provided with a mechanism ensuring its relative axial movement along the drive shaft. For any relative movement of the limiter
    it is necessary to make considerable efforts due to the large amount of friction force between the limiter and the drive shaft, since at the initial moment they are motionless relative to each other. The need for considerable effort in adjusting the suction stroke of the plungers leads to the complication of the pumping device and the increase of its metal intensity.
    The purpose of the invention is to simplify the design by reducing the effort to adjust the performance of the pumping device.
    The goal is achieved by the fact that in a pumping device for injecting liquid fuel into cylinders of an internal combustion engine, a housing is installed in the housing with the possibility of synchronous rotation and a distributor connected to the engine through a clutch unit and a drive shaft having a transverse channel in which plungers are located and an axial channel communicating alternately, in rotation of the distributor, an interplunger cavity with an inlet line or a pressure line, located around the distributor in the zone of the transverse channel an annular cam washer with an internal working profile, a pusher consisting of a bapmak located at the outer end of the plunger, and a roller coupled to the working profile of the cam washer, a suction stroke limiter of the plungers, including additional inclined surfaces that mate with each other on the plunger shoes and a stop located around the distributor in the zone of the transverse channel, and a control mechanism, a distributor separator installed in the housing with the possibility of movement relative to the axis of rotation and interaction TWI with a control mechanism, and the support is rigidly fixed on the drive shaft. In addition, the control mechanism is made in the form of an elastic element located on one side of the distributor and a lever located. on its opposite side to move the distributor against the action of the elastic element. The control mechanism is made in the form of an elastic element located on one side of the distributor and a hydraulic strip located on the opposite side to create a control pressure acting on the face the surface against the action of the elastic element directly or through an intermediate element. Moreover, the elastic element is located between the drive shaft and distributes the beam, and the end surface is located at the opposite end of the distributor. In addition, the hydraulic cavity is made in the form of a hydraulic chamber in the drive shaft and the outer side of which is located in the hydraulic chamber and the other side is connected to the distributor. And between the elastic element and the valve is a gasket. In this case, the coupling unit of the drive shaft with the distributor is made in the form of a longitudinal slot on the support in which the pusher is located, and the radial pin connecting the plunger with the pusher. FIG. 1 shows the proposed device, a general view, a longitudinal section, in FIG. 2 - the same, longitudinal section along a different axial plane; in fig. 3 - the device, a cross-section in the area of the filling channels; in fig. 4 - the same, in s not injection channels; FIG. 5 is the same in the area of the suction stroke limiter of the plungers; FIG. 6 shows schematically a part of the control mechanism; in fig. 7 shows an embodiment of the control mechanism in FIG. 8 shows an embodiment of the distributor; figure 9 - distribute the cross-section; in fig. 10 shows an embodiment of the device in FIG. 1, longitudinal section in the area of the suction stroke limiter plunger; in fig. 11 is a sectional view in FIG. ten; in fig. 12 is a section BB in FIG. ten; in fig. 13 is a detail of the device in FIG. 10. The pumping device comprises a housing 1, usually having the shape of a cup 2, the open end of which is closed by a fastener 3. The housing 1 has perforated legs 4 for fastening the housing to the engine. The cup .2 houses a drive shaft 5, which during operation is associated with the engine so as to rotate synchronously with it. The drive shaft 5 passes into the cylindrical chamber 6 formed by the cup 2 and the lid 3 of the housing 1, and has an extended shank 7 disposed therein. In addition, on the outer side of the drive shaft in the cup 2 there is an oil seal 8 and a bearing bush 9, and on the shaft there is a rotor of the fuel-priming pump 10, the cavity of which is bounded on one side by the cup 2, and on the other by the annular plate 11. The rotor of the fuel-priming pump 10 is equipped with blades mated to an eccentrically shaped cylindrical surface 12, forming the cavity of the fuel ™ of the priming pump 10, which has a supply of 13 and the outlet 14 and the bypass with a valve channels. A cover 15 is provided in the lid 3, in which the sleeve 16 is fixed. In the sleeve 16, a distributor 17 is arranged rotatably and relatively longitudinally, having an expanded head part 18 located in the cylindrical chamber 6. In the head part 18 of the distributor there is a transverse channel 19, which houses the plungers 20 forming the interplunger cavity 21 communicated with the axial channel 22 made in the distributor 17. On the lateral surface of the distributor 17 there are two diametrically located products Special notches 23 communicated with axial channel 22 of radial channels 24, and a longitudinal distribution groove 25, also connected with axial channel 22. In sleeve 16, filling channels 26 are made in the sleeve 16 of the plane of the longitudinal notches 23 of the valve, which are connected to an inlet line consisting of an annular groove 27 connected to the outflow channel 14 of the fuel-priming pump 10 through the valve 28 controlled by the electromagnetic device 29, and in the plane of the distribution groove 25 - discharge channels 30, each of which is connected to one of the upper lines 31 Tany equipped with an injection valve 32. If necessary, one of the longitudinal grooves 23 can communicate with the axial channel of several radial channels 24, the number of which is equal to the number of injection channels.
    An annular cam disc 33 with an internal working profile 34, which is formed by one, two, three, etc., is located around the head part 18 of the distributor 17 in the zone of the transverse channel 19. pairs of diametrically located, working cam projections depending on the number of engine cylinders serviced by the pump. In addition, the cam washer 33 can be rotated at some angle relative to the distributor 17 by means of a hydraulic device 35, which regulates the fluid pressure and connected to the ring washer 33 by means of a radially located stud 36. The hydraulic device 35 usually contains a spring-loaded piston placed in a cylinder to one the end of which is pressurized fluid to actuate the piston against the action of the spring.
    At the outer ends of the plungers there are pushers consisting of a shoe 37, coupled with the outer end of the plunger, and a roller 38, coupled with a working profile 34, cam cvr washers 33 and held in the shoe 37. On the lateral edges of the bashmak 37, along the axis of the distributor, additional inclined surfaces 39 are made. The pushers are held axially relative to the distributor 17 by means of side plates 40 and 41, which are attached to the lateral sides of the head 18 of the distributor 17. Typically, the side plates 40 and 41 have an oblique shape with a pair of outwardly extending diametral projections 42.
    The extended shank 7 of the drive shaft 5 has diametrically arranged longitudinal stops 43, each of which has a longitudinal slot 44, and on the inner side there are additional inclined surfaces 45. Inside the longitudinal slots 44 of the stops 43 there are pusher shoes 37 and diametrically protrusions 42 of the side plates 40 and 41 through which the rotational movement of the drive shaft 5 is transmitted to the distributor, with additional inclined surfaces 39 of the shoes 37 and additional inclined surfaces .45 of the stops 43 of the interface s between each other. Thus moving the plungers 20 outward, i.e. their suction stroke is determined by the suction stroke limiter of the plungers, made in the form of additional inclined surfaces 39 and 45, respectively, located on the pads 37 of the pushers and stops 43, of the drive shaft 5, and the stroke amount is changed by axial displacement of the distributor 17.
    The axial movement of the distributor 17 is carried out by a control mechanism, which can be performed either mechanically or hydraulically. The control mechanism in the mechanical version is usually made in the form of an elastic element, such as a cylindrical compression spring 46, placed in a blind hole 47 of the drive shaft 5 on the side of the head part 18 of the distributor 17, and a lever 48 located on the opposite side of the distributor 17. One end of the lever 48 is connected with the control system (not shown) and the other through the intermediate element 49 - with the end of the distributor 17. The hydraulic control mechanism is usually made in the form of an elastic element, for example cylindrical compression spring 46, placed in blind drilling 47; Drive shaft 5 from the side of the head 18 of the distributor 17, and hydraulic cavity 50 located on its opposite side and limited by the end of the distributor 17, part of the lateral surface of the cylindrical bore 15 and the cover 51 closing hole 15. Hydraulic cavity 50 communicates with outlet channel 14 of fuel priming pump 10 through choke 52 located in sleeve 16 and also with cylindrical chamber 6, which communicates with drain (not received) through this ektromagnitny valve 53. At krshke 51 fixed adjustment position sensor 54 distributed divisor 17. Typically, sensor 54 has a portion, which is disposed on the distributor. In each case, the force of the elastic element is directed against the action of either the lever 48, or the fuel pressure in the hydraulic cavity 50, and the force required to move the distributor 17 is slightly greater than that reported by the spring 46, since the friction between the distributor 17 and the sleeve 16 is minimal , since when this takes place the relative rotation of these two parts. In addition, the control mechanism can be made in the form of a hydraulic chamber 55 located in the drive shaft 5, and a piston 56, one end of which is placed in the hydraulic chamber 55 and the other side is coupled to the end face of the head part 18 of the distributor 17, with the hydraulic chamber 55 communicating with the tapping channel 14 of the fueling Hacocd 10 through the annular recess 57 and the throttle and is controlled by a valve (not shown) similarly (the throttle 52 and the electromagnetic valve 53. In this case, the elastic element in the form of a helical spring 58 is set to counter the positive end of the distributor 17 and the interface with its end through a gasket 59 made of synthetic resin or metal.The support slider 59 can be separated from the end of the distributor by a film of fuel supplied to it via a throttle from the exhaust channel 14 of the fuel priming pump 10 (not shown), and the spring may be provided with a knob adjuster 60. The annular recess may be formed by parts of the bearing sleeve 9. In another embodiment of the axial device, the distributor 17 may be provided with an additional radial anal 61, which extends to the outer surface of the distributor and connected with the axial passage 22. Radial passage 61 is normally closed by a sleeve 16, except SLE cha, when valve 17 is set to minimum fuel supply or even at zero flow. In this position, the distributor moves to the extreme left position, in which the rollers 38 of the plunger pushers 20 cannot contact the working profile 34 of the cam washer 33, and even if they contact it, as can happen when the working profile 34 has a special form for regulating the removal of fuel at the end of supply, any movement of the plungers 20 will not lead to the supply of fuel to the engine cylinders, since the additional radial channel 61 communicates the axial channel 22 with the chamber 6 and with the drain. This channel can also be used to clean the device with air after manufacture or during maintenance, or in the case where air enters the various channels of the device. It is also possible to carry out an additional channel 61 in the immediate vicinity of the transverse channel 19 for removing air from the axial channel 22 that has entered it with fuel from the inlet line. The displacement node of the drive shaft 5 with the distributor 17 is usually made in the form of longitudinal slots 44 stops 43, pusher shoes 37, passage 1 inside the slots 44, and side plates 41, diametrically protrusions 42 of which are also inside the slots, or in the form of longitudinal slots 44 , shoes of 37 pushers extending inside slots 44, blind holes 62 in the plungers, holes in the shoes 37, and stepped radial pins 63, the wider ends of which extend into the holes 62 of the plungers 20, and narrow ends pass through the holes of the shoes 37 pusher it ends in circular grooves made in the rollers 38. In yet another variant of the pumping device, the distributor 17 may be provided with additional discharge channels 64 arranged at an angle in accordance with the main discharge channels 30. The additional pressure channels 64 have a limited flow area and are in such an axial position that at the time of installation 91 of the distributor 17 for supplying excess fuel the distribution groove 25 coincides with them. The inner ends of the channels 64 are communicated with the axial channel 22 and when fuel is injected, some of it passes through one of them. If air is present in the channels, it is removed with a portion of the fuel through channels 64 during normal operation of the device. The stops for the pushers of the plungers 20 are rigidly mounted on the drive shaft 5 and can be made either together with the shaft 5 in the form of a shank 7 or in the form of a separate and-shaped clamped part 65, which is conjugated to the shaft 5 by means of spline projections and depressions, as well as a spring element 66 and a shaft 5, located in the shank, formed in the form of a cylindrical cup 67 with diametrical gaps 68, in which stops are placed. The device works as follows. The drive shaft 5 is connected at one end with the engine and rotates synchronously with it, and the other end through the clutch assembly with the distributor 17 and transmits rotation to it ,. When the drive shaft is rotated, the topdivage priming pump 10 supplies fuel to the filling channels 26 through the discharge channel 14, the valve 28 and the annular groove 27. The plungers 20 rotate together with the distributor 1 and under the action of the working profile 34 of the cam washer 33 perform reciprocating movement in the transverse channel 19, simultaneously changing the volume of the interplunger cavity 21 When the radial channels 24 coincide with the filling channels 26, the fuel enters the interplunger cavity 21 through the axial channel 22 and the plungers 20 move outside y A further rotation of the distributor 17 causes the radial channels 24 to separate from the naps & ample channels 26, the pusher rollers 38 slide over the cam projections of the cam washer 33 and move the plungers 20 inwards, feeding fuel from the interplunger cavity 21 through the axial channel 22 combined at this moment with one of the discharge channels 30 through the distribution groove 25, to the corresponding discharge line 31. Regulation of the amount of fuel supplied by the pump during each cycle is provided by the axial position of the distributor 17, which is varied by the control mechanism. The axial displacement of the distributor 17 leads to a relative displacement of the additional inclined surfaces of the pusher and the stop, which leads to a change in the suction stroke of the plungers and thereby the amount of fuel supplied. The movement of the distributor in the direction of the target of cyclic feeds is carried out under the action of either the lever 48, or pressure in the hydraulic cavity 50, and in the direction of increasing the cycle feeds under the action of the elastic element. Regulation of the moment of fuel supply to the injection line 31 is controlled by rotating the annular cam washer 33 around the axis of rotation of the distributor under the action of a hydraulic device 35. regulating the pressure through the pin 36. Performing a pumping device with a valve moving from the axis of rotation reduces the force required for changes in the cycle fuel supply, which simplifies the control mechanism and the pumping device as a whole, and this in turn increases the reliability and efficiency of the engine.
