Pneumatic cylinder unit for e.g. textile engine, has end position damping device with sealing units arranged at base and top cover, where piston facing area of device has rigidity larger than that of another area turning away from piston

摘要

The unit has an end position damping device with sealing units (9a, 9b) to lock pressurizing medium openings in an end position of a piston (3), so that a residual pressuring medium in pressure chambers flows via bypass openings. The units are arranged at a base (5) and a top cover (6), where the piston facing an area (12a) of the device has rigidity larger than that of an area (12b) turning away from the piston.
