TRACTION/COMPRESSION BUFFER FOR COUPLING DEVICES ON RAIL ANDWHEEL-MOUNTED VEHICLES

摘要

A traction/compression buffer for coupling devices on rail and wheel-mounted vehicles comprises a housing (1) and a piston element (3), which projects ou t of said housing on one side and which can be moved out of a zero position in two directions against the resistance of a spring device and a damping devic e. A hydraulic damping device is provided for damping the return movement of th e piston element (3) out of the position in which it is drawn out of the housi ng (1), in the direction of the zero position. Said hydraulic damping device comprises a ring-shaped hydraulic working chamber (32) that surrounds the piston element (3) and that is connected to an overflow chamber (29) by at least one overflow channel (31).
