DEVICE FOR AUTOMATIC CONTROL OF SPACE IN MECHANISM FOR OPERATING FRICTION CLUTCH Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: clutch has operating mechanism the housing of the hydraulic cylinder of which is separated into two spaces by a baffle. There are pistons inside the spaces. The reverse spring of the inlet space piston is interposed between the piston and the baffle. The spaces are interconnected through a passageway provided with a valve member set on the inlet space piston which is mounted on the rod of the second piston for permitting connection with it through a one-way stroke mechanism. The mechanism is provided with pressing flexible member interposed between the axial seal of the inlet space piston and locking balls. The part of the rod of the second piston that is in a contact with the rod is provided at least two ring grooves for flexible members. EFFECT: enhanced reliability. 1 dwg
