QUICK-RELEASE UNIT Russian patent published in 2001 - IPC

FIELD: separation of interunit pneumohydraulic service lines in rocket engineering, can be applicable in mechanical engineering. SUBSTANCE: the quick-release unit consists of on-board and ground blocks connected by a lock consisting of a gripping mechanism in the form of a collet with a movable locking bush, pneumatic drive with a piston. The movable locking bush is provided with a lug for attachment of the pulling-off device. The on-board block has a closed chamber with a check valve, that is connected to the working medium feed system, and a T-shaped duct with a pneumatic drive. In the intersection of the T-shaped duct provision is made for a cavity restricted by two packing members and overlapped by a spring-loaded piston located in the on-board block and having a pusher resting on a restrictor rigidly linked with the movable locking bush engageable with the pneumatic drive piston. EFFECT: enhanced reliability of actuation of the locking device of the quick-release unit at separation of the on-board and ground blocks. 3 dwg
