Abstract
The disclosure is directed to a hydraulic cylinder with an improved cushion device thereon to enhance the operational characteristics thereof. A cushion pin is affixed to the cylinder piston by a cap screw in such a manner that the cushion pin can float about the screw relative to the piston. Optional orifices in the cushion pin provide an additional fluid flow passage whereby the metering action between the pin and a fluid flow port to the cylinder is different for retraction and extension of the piston.
