    The invention relates to an infinitely variable transmission provided with an endless transmission member (4) and at least one V-shaped pulley (2, 3) of which at least one sheave (3) is rigidly connected to a hydraulic cylinder-piston (5, 7) unit for the axial displacement of this sheave (3). The said cylinder-piston unit (5, 7) being provided with a pressure-equalizing chamber (13) for the compensation of pressure rises in the cylinder space (6) due to centrifugal forces. The pressure-equalizing chamber (13) can be supplied with fluid from the cylinder space through a charging port (14). In order to overcome the drawback of particles obstructing regularly the charging port (14), ahead of the charging port (14) a filtering member is provided through which the fluid flow must pass.

    2, the pulley according to claim 1, distinguishing rout and so that the filter element is made in the form of a wire mesh.
    3.Smite popp. 1 and 2, characterized in that the mesh size of the wire mesh is 0.3-0.9 times the diameter of the inlet, and the total useful area of the invention relates to mechanical engineering, in particular, to V-belts, and can be used in B transmissions with flexible coupling in any branch of the national household.
    The aim of the invention is to increase the sensitivity of the adjustment of the V-belt variator pulley and its reliability by simultaneously cleaning the fluid in the pulley hydraulic cylinder and compensating for the additional pressure in the hydraulic cylinder cavity,
    Fig. 1 shows a pulley, one of the cones of which is integral with the hydraulic cylinder, a partial longitudinal section; FIG. 2 shows a cork with a hole and a grid, a longitudinal section.
    The V-belt variator pulley contains a tapered disk 1 rigidly fixed on the shaft 2, and a movable conical disk 3 mounted on the shaft 1 by means of a keyed joint with the possibility of axial movement and rotation together with the shaft 1. The movable conical disk 3 is rigidly connected to the hydraulic cylinder for the axial Moving this conical disk, the Hydrozylinder comprises a housing 4 and a piston 5 with an inlet 6 that divides the hydraulic cylinder into two cavities 7 and 8, one of which (8) is a pressure equalization chamber. A filtering element 9 is installed in front of the vaus opening from the side of the cavity 7, which has a plurality of holes the size of which is smaller than the diameter of the inlet 6, and the total area of all ogs: more than the sectional area of the inlet 6, In addition, the filtering: ijfPMeHT 9 can be 25 times larger inlet area,
    4. Popp pulley, 1-3, characterized in that the filter element is fixed in the inlet opening by means of a hollow plug,
    5, a pulley according to claim 4, characterized in that the floor stopper has a shoulder in which a wire mesh is fixed.
    Filled in the form of wire mesh. The mesh size of the wire mesh is 0.3-0.9 of the diameter of the inlet 6, and the total useful area B is 10-25 times the cross-sectional area of the inlet 6, In addition, the filter element 9 is fixed in the inlet 6 by means of a hollow plug 10. With this floor
    the plug 10 has a shoulder 11 in which a wire mesh is fixed by means of a frame 12.
    A belt 13 is put on the V-belt variator pulley. A spring 14 is installed between the movable cone 3 and the 5-cylinder piston piston. In the shaft 2, the channels 15 and 16 are made for supplying fluid to the cavity 7 of the hydraulic cylinder. The pulley works as follows
    During operation of the V-belt variator, the working diameter of the belt 13 depends on the distance between the legs; with tapered discs 1 and 3, the spring 14 creates some preload on the movable
    tapered disc 3 and through it provides pre-view tension of the belt 13.
    Fluid under pressure is fed into cavity 7 grams of the cylinder 1 and the channels 15 and 16, as a result of which the pressure in cavity 7 is pulled out and the movable conical disk 3 moves towards the conical disk 1. At the same time, the belt 13 is acted upon by a compression force the diameter of the belt is 13 and its tension. The liquid then flows through the inlet 6 in the plug 10 into the pressure equalization chamber 8, which communicates with the surrounding atmosphere.
    the sphere through the colper click
    between the outer periphery of the hub of the piston 5 and the radially located part of the wall of the housing 4 of the hydraulic cylinder. The slit has such a width that the pressure in the pressure equalization chamber near the slit is equal to the ambient pressure. Therefore, the pressure in the pressure balance chamber during rotation of the hydraulic cylinder is created almost exclusively by centrifugal forces. The pressure created in the pressure equalization chamber leads to a decrease in the clamping force acting on the re
    less and therefore partially compensates for the additional pressure in the cavity 7 of the hydraulic cylinder. The liquid from the cavity 7 of the hydraulic cylinder passes into the pressure equalization chamber through the inlet 6 in the plug 10.
    The presence of the filter element 9 ensures the cleaning of the fluid, eliminates the clogging of the inlet 6, increases the reliability of the pulley, and compensating for the additional pressure in the cylinder cavity increases the sensitivity of the pulley adjustment.
