摘要: This disclosure is directed to a multi piston, double acting, fluid actuated power pack various tools between an operative and inoperative position attain maximum with limited displacement of the operating piston. attained by comprising housing partitioned define plurality piston chambers having head reciprocally disposed in each chambers. The heads are connected rod which activated extended retracted as pressure exerted on heads. Control means form valve associated passages operatively respective for directing flow from manner wherein applied stroke, only at least one return stroke.
