VARIATOR Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: driving and driven pulleys are mounted on hollow shafts. The pulleys are coupled with a flexible connection. Each of the pulleys has hydraulic cylinders provided with rods and flexible plates and connected with the shaft space. The flexible plates define the working surface of the pulleys. A bent plate is fixedly mounted with respect to the rotating pulley on the side, which is not loaded by the flexible connection, inside the spaces. The flexible plate cuts off the fluid supply to the unloaded hydraulic cylinders to synchronize the cylinders. EFFECT: enhanced reliability. 5 dwg
