Abstract
After the piston, in a piston/cylinder type fluid pressure motor, has moved past the fluid discharge port during termination of the stroke, fluid is forced to flow through a circuitous conduit formed into the outer surface of the piston. The rate of deceleration of the piston is proportional to the length, cross-sectional area, and surface finish of the channel forming the conduit.
