Pneumatic jack has the following description of the shock absorber and advantages of the damping of a pneumatic jack

摘要

Mechanism for a pneumatic jack whose cylinder body comprises, at each end, the damping chambers. / p & & p & a member of a differential pressure intake valve 76, 112 and a valve member 80 discharge, 116, are interposed between each of the damping chambers 50, 52 and the supply of compressed air 132, and a damping member 54, 88 is interposed between each damping chamber 50, 52 and the bore of the body of jack 32 and is likely to be pushed in position for damping by the piston 34 of the jack. / p & & p & application to the embodiment of the shock absorbers of the end of travel of the actuator able to absorb the energies kinetics castings.
