ABSTRACT:
An improved work machine of the eccentric piston type which may be employed to translate force of pressurized fluid into rotary shaft motion in an external combustion type engine system, as a pump for pumping fluids in a fluid handling system, and as a fluid actuated motor. The work machine comprises a housing having an internal compartment with a peripheral lobe. An inner body is mounted for non-rotational orbital movement in the housing. The inner body housing, and a movable wall member located in a peripheral recess of the inner body form variable-volume fluid intake and discharge chambers in the housing compartment during orbital movement of the inner body. Pressurized fluid supplied to the fluid intake chamber of the housing imparts non-rotational orbital movement of the inner body in the housing and corresponding rotational motion to an output shaft on which the inner body is eccentrically mounted. Alternatively, power may be supplied to the output shaft of the work machine to rotate the same and cause orbital movement of the inner body for use of the work machine as a pump in pumping fluids through the variable-volume chambers of the housing of the work machine. The direction of orbital movement of the inner body and rotational movement of the output shaft may be reversed by simply reversing the flow of pressurized fluid through the housing compartment of the machine.
