LOCKING UNIT Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: unit has a device for exhibiting resistance to axial movement of an axially movable piston. A collar is made on the rod for interaction with the resisting device. The resisting device is constructed as two chambers of the same diameters positioned on the diametrically opposite sides of the rod. Movable members made up as bellows and pistons are received in the chambers. The bases of the members are interconnected through a rod. The rod is received in the lateral slot of the rod. The base of one of the bellows and pistons is provided with a collar for interaction with the rod collar. There is a passage for hydraulic control of characteristics of the resisting device in the housing of at least one of the chamber. EFFECT: enhanced reliability. 2 dwg
