ABSTRACT:
What follows is a description of a hydraulically powered actuator for producing a reciprocating output and a method which produces a reciprocating output in response to the controlled flow of a hydraulic fluid. The hydraulic actuator includes, in one embodiment, a cylinder within which a piston assembly is reciprocated, the cylinder being itself displaceably mounted within a housing so that it can periodically introduce a unique flow passage through which a rapid fluid flow occurs, the provision of the passage reduces the hydraulic power lost during reciprocating movement of the piston assembly and ensures a high energy output.
