ABSTRACT:
An intensifier type of fluid actuator includes a body including a first manifold connected by a first tube to a second manifold to define an intensifier chamber, a third manifold connected by a second tube to the second manifold to define a reservoir chamber, and a fourth manifold connected by a third tube to the third manifold to define a work chamber. A reservoir piston is disposed within the reservoir chamber and has an outer surface in sealing and sliding engagement with the second tube. The reservoir piston includes an inner surface defined by a central opening formed therethrough which extends from a first end of the reservoir piston adjacent to the second manifold to a second end of the reservoir piston adjacent to the third manifold. A passageway is formed in the reservoir piston which extends from the inner surface to the outer surface, thereof. A check valve assembly is disposed within the reservoir piston which permits the one-way flow of fluid from the passageway to the first end of the reservoir piston.
