    The purpose of the invention is to reduce the switching time of the switchgear and reduce the dynamic loads by achieving the maximum swing speed in the middle zone of the turn path and reducing this speed on the end sections of the track.
    FIG. Figures 1-4 show the distribution valve drive circuits, variants; in fig. 5 is a variant of the drive circuit of the distributor-socket using two hydraulic cylinders J in FIG. 6 — a diagram of the speed of movement of the distribution socket.
    A two-cylinder pump of viscous liquids contains a frame 1, a distributing device for alternately connecting one of two working cylinders (not shown) with a pressure pipe (not shown), including installed with a swing with a variable speed around a fixed axis 2 between two end positions. pipe 3 (pipe 3 is shown in one final position, the second position is symmetrical to the middle position shown in the vertical plane passing through the swing axis 2), having a lever 4 for kinematically communication with the output link 5 of the drive unit having at least one hydraulic cylinder 6 s the piston 7, the kinematic connection between the output link 5 of the drive unit and the lever 4 of the distributor of the divider pipe 3 is made with at least one of the transmission link connected to each of these elements by means of a hinge of compound to that obtained on the possibility of permanent changes the effective lever arm length of the pipe 4 to 3, with the last turn.
    The transmission link can be made in the form of a yoke 8, the axis of rotation of which is fixed to the frame 1, as shown in FIG. 1. In this case, the swivel joint of the transmission link - the rocker arm 8 c) the lever 4 of the distribution pipe 3 is made in the form of a sleeve 10, which grips the lever 4 and is fixed
    on the rocker arm 8 with the possibility of rotation.
    I The drive unit can be equipped with a rack and pinion gear, the rail 11 of which is connected to the pistons 12 of the hydraulic cylinder-13, and the gear wheel 14 is connected to the rocker arm 8 (Fig. 2 and 3) while the rocker arm 8 is connected to the lever 4 of the distribution pipe 3 by means of bar 15, installed with the possibility of transmitting both tensile and compressive forces. In the embodiment shown in
    FIG. 2, FILLERS 12 WITH ASSISTANCE

In the embodiment shown in FIG. 3, the hydraulic cylinder 13 is rigidly connected to the frame 1, and the bodies 12 are connected by a rail 11 and are installed with the possibility of reciprocating movement in the hydraulic cylinder 13.
    The beam 8 can be made triangular (Fig. 4) and its connection with the output link 5 of the drive
    the node is made using a hinged-lever mechanism, including levers 17 and 18, link 19, rigidly attached to the frame 1, and hinge axes 20-23, while the rocker arm 8 is connected to the lever 4 of the distribution pipe 3 using a rod 24.
    The pump can be equipped with an additional transmission link. And each of the transmission links is designed as a rocker arm 8 (8) with a rod 25 (25), which have an individual drive hydraulic cylinder 6 and 6, respectively. Each actuating hydraulic cylinder 6 (6) has a piston 26 (26) and a rod 27 (27) cavity, which with the help of a control valve 28 can be connected to sources of pressure and drain in the form of hydraulic lines 29 and 30. Each of the actuating cylinders 6 (b ) in the embodiment of the pump shown in FIG. 5 is provided with an additional inlet 31 (31) located in the middle zone of the hydraulic cylinder 6/6) and communicated by an external pipe 32 (32) with the inlet of the piston cavity 26 (26), while the rod cavities 27 and 27 of both hydraulic cylinders 6 and 6 are interconnected by external pipeline 33.
    The ratio of the shoulders of the transmission link and the lever 4 of the distribution pipe 3 is chosen in such a way as to shorten the switching time of the switchgear and reduce the dynamic loads by achieving the maximum swing speed in the middle zone of the turning path of the pipe 3 along the arc 34 described from the swing center coinciding with the axis 2, and decrease of this speed on the end sections of the path, the ratio of the sizes of the shoulders / B, where A is the distance between the axis 9 of rotation of the transmission link 8 and the axis of its articulation with the lever 4 of the distribution The output port 3 at the end positions of the distribution pipe, A is the same distance with the middle position of the distribution pipe, B is the distance between the pivot axis of the transmission link 8 with the lever 4 of the distribution pipe 3 and the axis 2 of the rotation of the distribution pipe 3 at the end positions last
    and B is also the distance with the average position of the distribution pipe 3. In the diagram (Fig. 6), curve 35 shows the change in the speed of movement of the distribution and pipe 3 in the proposed pump, curve 36 shows the change in average speed, and curve 37 shows the change in speed -, P9sti in the well-known pump, points 38 i, indicate the final position of the nozzle 3, and point 40 - its average position.
    A two-cylinder pump for viscous liquids works as follows.
    After the end of the pump stroke in one of the working cylinders, the distribution pipe 3 is in one of the final distortions. To transfer the distributor pipe 3 to another end position (Fig. 1), pressure is applied to the piston cavity 26 of the hydraulic cylinder 6, the output link 5 acting on the beam 8 and the latter turning around axis 9, the sleeve 10 acting on the lever 4 and the distributing pipe 3 rotates around fixed axis 2 to another end position.

    the latter is moved to the right, whereby the gear wheel 14 interacts with the rail 11, which leads to the rotation of the rocker arm 8 together with the rotation of the gear wheel, and the movement of the lever 4 and the pipe 3 around the axis 2 to the other end position by the rod 15.
    In the embodiment shown in FIG. 3, when pressure is applied to the working cavity of the hydraulic cylinder 13, the pistons 12 move together with the rail 11, driving the gears to rotate the gears 14 and the rocker arm 8 associated with it, and the rod 15, acting on the lever 4, turns the nozzle 3 around the axis 2 to another. final position.

    In the embodiment of the pump shown in FIG. 5, the rotation of the distributor nozzle 3 is carried out as follows. When pressure is applied to the hydroline 29 while it is polio; of the control valve distribution body 28 in the position shown in FIG. 5, pressure enters the piston cavity 26 of the hydraulic cylinder .6 and through the pipeline 32 into its rod cavity 27, from which pressure passes through the pipeline 33 to
    rod end 27 hydraulic cylinders

    axis 9; in this case, the rod 25 connected to the yoke 8 moves the lever 4 and rotates the associated pipe 3 around the axis 2 to the middle position, further moving the pipe 3 after the piston has blocked it

    In all these cases, the speed of movement of the nozzle 3 has the character of a curve 35, shown in FIG. 6, which reduces the dynamic loads in the distribution unit and shortens the switching time of the pump switchgear.
