CYLINDER-PISTON UNIT FOR CREATING AND TRANSMITTING PRESSURE Russian patent published in 1995 - IPC

FIELD: hydraulics. SUBSTANCE: plunger is received in the sleeve-shaped piston from its open side. The plunger is mounted for permitting movement with an inclination to the direction of compression. One end of the plunger is projected out of the piston. The plunger is sealed by way of ring sealing members with respect to the inner side of the piston and interacts with the adjusting member. The other plunger end, which is semi- spherical, interacts with the semi-spherical socket of the bearing members received in the inner space of the piston. The member is mounted for permitting movement with respect to the piston and spring-loaded relatively to it. The spring is interposed between the bottom of the piston and bearing member. The ring sealing members are made up as interacting conical surfaces provided on the inner wall of the piston and outer side of the plunger. EFFECT: enhanced efficiency. 6 cl, 5 dwg
