Abstract

A piston-cylinder combination having a piston arranged for reciprocating movement within a cylinder under fluid pressure, the fluid pressure being ultimately delivered to the sides of the piston with a connector rod from the piston controlling the movement of valves for the delivery of fluid to the piston. The fluid valves are alternatively exposed to fluid under pressure to insure proper opening and closure thereof. The valving combination from the alternate sides of the piston eliminates chattering or floating of the piston, particularly when the piston is under a "no load" condition.
