Abstract: A piston cylinder assembly includes a piston rod reciprocatively mounted within a piston chamber, and a piston fixed to the rod within the chamber. A pair of ports are mounted on opposite ends of the cylinder chamber in fluid communication therewith, each one of the ports having a laterally extending portion adapted to be connected in fluid communication with a source of fluid under pressure and having an axially extending portion opening into the interior of the chamber. A tapered seal is mounted on one of the end portions of the piston for sealing the axial portion of one of the ports to provide a cushioned movement of the piston at the terminal end of its stroke. A sleeve member extends axially within the last-mentioned axial portion of the port and terminates at one of its ends at a position disposed opposite the lateral portion of the port. A bleeding device permits fluid to leave the chamber as the seal engages sealingly the sleeve member so that the terminal portion of the piston stroke is cushioned.
