Abstract

Described is a drive assembly (20) and a production assembly (22) for use in producing reciprocating motion. In one embodiment, the drive assembly is formed as a flexible hose hydraulic cylinder that uses a source of fluid pressure to extend and retract a flexible hose. One or more valves are available to regulate the pressure within the flexible hose. A reciprocating member is connected to the flexible hose. Extension and retraction of the hose cause corresponding translation in the reciprocating member. In one embodiment, the reciprocating member is a piston rod that is biased in one direction.
