Title:
TRACTION/COMPRESSION BUFFER FOR COUPLING DEVICES ON RAIL AND WHEEL-MOUNTED VEHICLES
Document Type and Number:
WIPO Patent Application WO2000065248
Kind Code:
A3
Abstract:
A traction/compression buffer for coupling devices on rail and wheel-mounted vehicles comprises a housing (1) and a piston element (3), which projects out 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 device. A hydraulic damping device is provided for damping the return movement of the piston element (3) out of the position in which it is drawn out of the housing (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).
