Abstract (en)
[origin: EP1605171A2] The working cylinder (1) operated by pressure medium and with an integrated blocking system (4) for mechanical travel locking has a threaded spindle (6) interacting with the female thread of a piston, and an axially movable locking disc (5) is fitted on the bottom end of the spindle. A blocking sleeve as a concentric double-collared sleeve (17) inside the rotating spindle acts as a fluid guide for the separation of the pressure-orientated inflow to the delivery-orientated outflow during axial flow of the two main streams of a pressurized flow consumer.
