    The invention relates to a maternity system, more specifically to dvt-atelestroyeniyu, but specifically to the first device, and can be used in the drive mechanisms for the fuel pump of the reverse two-stroke internal combustion engine. spenzelzush kzshachkrvy shaft with works cams, plunger pusher, consisting of a guide, connected with myiir with the possibility of joint reciprocating movement in the right direction, perpeptplug the cam shaft, l siabzheshaya spring, acting: on the guide towards the cam shaft and the promszhutopyugo element at one end of which}) the driven roller is positioned, (1b; th with the working cam, and the other end of it is connected with the directional roller, A joint with an axis, the axis of which is located paralysis of a cam shaft, “noBO) oia node of an intermediate element around the hinge between two extreme positions symmetrical with respect to nriocKociif, pro: draw through the axles of the harpira and the camshaft .1, HH) 1 dry There is an intermediate element with 1p in the TOIUWB natural pump mechanism of the pogo pump: sp1 (Ly11 with a camshaft. And the plunger pusher moves along the pivot assembly i) j50Me KyTCuioro of the element consisting of several of its own carapaces which, when the engine of the couepLuaioT is stationary oscillatory, are engineered and require the organization to supply lubricant to the friction pairs, the weight this leads to the condition / iCHeHjno of the mechanism design and. reducing its reliability. In addition, the potential of a transverse component force in the transmission of the cam from the cam to the plunger, transmitted to the component parts of the turning unit of the intermediate element, reduces the reliability of the drive mechanism and the fuel pump as a whole. The possible reduction of the required force is the drive of yy to an increase in the length of the intermediate element, and thus to the complication of the layout of the fuel pump on the engine. The aim of the invention is to increase the reliability of the drive mechanism. The goal is achieved by the fact that in a single mechanism for a fuel pump for a reversible internal combustion engine PIA containing a camshaft with working cams, the thrust piston P1-1 is composed of a guide connected to the plunger with the possibility of reciprocating reciprocating movement directional, perpendicular to the camshaft, and supplied with a spring acting on the tangent in the direction of the camshaft and nromezh) t: OP) th. element, isa at one end of which a driven roller is located, mated to the working cam, and the other end is connected to the guide through a shaft, whose axis is parallel to the axis of the camshaft, and the node of rotation of the intermediate element around the shaft between two extreme positions, symmetrical relative to the plane passing through the axis of the ball and the camshaft, the ipunger pusher is provided with additional bearing surfaces placed on the guide and intermediate element, additional elements The orifice surfaces are possible with the possibility of their noriapiroro conjugation i at the extreme positions of the second element. At the same time, the node of rotation of the intermediate element is made in the form of an elongated slide, parallel to the direction of movement of the guide pusher, a slider fixed on the inter-folding element in the center of the slide and placed in the slide with the possibility of reciprocating alternating currents in it, and a lever for shifting the slide in the direction perpendicular to its longitudinal axis and the axis of the shaft. Such an embodiment of the drive mechanism makes it possible to fully balance the operating between the working cam and the slave pojnu oM ycHJnie with two reaction forces, one of which operates in the joint connection of the intermediate element with the guide pusher and the other in the iHix that corresponds to the direction of rotation of the engine at the moment. Thus, the slave roller is completely transferred to the pusher guide, and the turning unit of the pro-slider between its extreme positions in the working remshme does not experience any stresses other than MOMeHta when reversing. Due to this, as well as the rigid fixation of the intermediate element in the extreme position that it currently occupies under the action of the force of the Slave roller, the desired stroke of the fuel plunger is maintained regardless of the back pressure changes to the pump plunger, and consequently, Acting during pump xo / jta between the roller and the cam. This makes it possible to select the shortest possible length of the intermediate element between the axles of the driven roller and the ball joint, and thereby reduce the overall dimensions along the height of the fuel pump. In addition, the technological requirements for fulfilling the component parts of the turning unit of the intermediate element, i.e. their conjugations can be made with the formation of several large gaps. FIG. 1 The drive unit shows a longitudinal section in a plane perpendicular to the axis of the camshaft; in fig. 2 - the same, the intermediate element is located in a different extreme position after reversing the engine; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section B-B in FIG. 3. The drive mechanism for the fuel pump comprises a cam shaft I rotating synchronously with the crankshaft of the engine I on the barrel is fixed to one for each fuel pump section working cams 2, plunder pusher consisting of guide 3 and intermediate element 4, and element 4, made in the form of an elongated link 5, slide 6 and lever 7 for displacing the couch 5. The guide 3 of the pusher is made in the form of a cup 8 with a central rod 9, in the protruding corner of which there is up to 10 A guide 3 with a plunger (not shown) in a known manner, for example, is similar to a bayonet. shutter, and is equipped with a spring consisting of the inner or outer 12 screw compression springs of prisoners between the cup 8 and the roof of the SPRING 13 of the bore of the pump body 14, in which the guide 3 is placed with the possibility of reciprocating with the plunger in the right direction perpendicular The cam shaft 1. The intermediate element 4 is connected at one end 15 by means of a hinge 16 to a guide 3, and at its other end 17 is located a rotary roller 19 rotatable around the finger 18, coupled by the action of helical springs 11 and 12 compressing with a working cam 2. The 111 joint 16 has an axis 20 which is located 1a parallel to the axis of the cam shaft 1 and around which the intermediate element 4 can rotate between two extreme positions symmetrical with respect to the plane passing through the axes of pole 16 and 16 camshaft 1. 1 24. The turning unit of the intermediate element 4 around the axis 20 of the hinge 16 is made in the form of an elongated piece 5 located parallel to the direction of movement of the pusher guide 3, a slider 6 fixed to the intermediate element 4 in the hinge area and 16 and placed in Cup 5 with a transverse 1p gap and the possibility of reciprocating movement in it, and a lever 7 housed in the housing 14. The arm 5 is fixed on the lever 7 at a determined point along its length. The lever 7 is connected to the engine reversal control system (not shown) to displace the link 5 between the two extreme positions in the direction perpendicular to its longitudinal axis and the axis of the roller 19, which causes the slider 6 to mix with it and thereby npoNJC of the element 4. The actuating element of the control system can be, for example, in the form of a pneumatic or hydraulic plunger or a rotary shaft running along the length of the engine and connected to the corresponding levers 7 intermediate connections and. Additional support surfaces 21–24 are made on guide 3 and spacing of the external element 4 of the plunger pusher with the possibility of pairing (21 and 22, 23 and 24) at extreme positions of the intermediate element 4. Additional supporting surfaces 21 and 23 of the guide 3 performed in the form of flat pads, located symmetrically to the longitudinal axis and diametrically on the bottom of the glass 8, and additional supporting surfaces 22 24 of the intermediate element 4 - in the form of flat pads located symmetrically to its longitudinal axis on the side projections 25. P ivodnoy mehash1zm works as follows. When the camshaft 1 rotates, for example, counterclockwise, and the intermediate member 4 is in the right extreme position, then the additional bearing surfaces 22 and 24 of the guide 3 and intermediate element 4 are conjugated to each other, under the action of the symmetric profile of the operating cam 2 and the coil springs P and 12 are compressed through the driven roller 19, the supporting surfaces 22 and 24, the rotational movement of the camshaft 1 turns into a reciprocating movement of the intermediate element 4 and the guide 3 with the plunger relatively wide The hull and the hyulzun 6 are relatively kul 5. When reversing the valve, the control panel doesn’t move the lever 7 together with the rocker 5 to the other extreme position and thus the intermediate element 4 rotates around the hinge 16 to match another pair of additional supports by means of the slider 6 surfaces 21 and 23, and cam shaft 1 begins to rotate in the opposite direction. Regardless of the direction of rotation of the cam lever 1, the direction of the force acting in contact between the worker 2 and the driven roller 19 and transmitted through the axis of the finger 18 to the intermediate element 4 changes depending on the profile of the working cam 2. When the driven roller 19 touches the lowest point the cam 2 profile directly - before the pump plunger moves upwards, the direction of the force takes the first extreme position and coincides with the line passing between the centers of the axes of the finger 18 and the camshaft 1, resulting in portion of the ram force is transmitted through the conjugated currently to

    “Va7, 6 optional support surfaces. Subsequently, when the cam profile is driven in by the driven roller 19, the direction of the force shifts towards the axis 20 of the hinge 16 and, not income, it reaches another extreme position, i.e. at any point of the cam profile 2, at least part of the transmitted force is on the adjoining additional bearing surfaces, which ensures the stability of the position of the intermediate element 4. Such an embodiment of the drive mechanism can be applied in reversible engines also with other devices driven by a symmetrical cam for example in engines with a purge dp of an exhaust valve actuator. The implementation in the drive mechanism of additional support surfaces, placing P-X on the guide and intermediate element with the possibility of pair-wise pairing with the extreme positions of the intermediate element, allows to simplify the design of the pump as a whole and increase its reliability.
