Abstract: An oil management system includes an engine housing assembly which defines a first rotor volume and a second rotor volume. An oil cooler assembly arranged between the first rotor volume and the second rotor volume.

Abstract: The problems of prior compressor structures relying upon conventional check valves are obviated by using, instead, flow control passages which operate to control flow while avoiding mechanical moving elements which may become problematical.

Abstract: The casing (1) of a positive displacement machine has a cylindrical internal surface (3) delimiting an operating chamber which accommodates an orbiting piston (4) having a cylindrical external surface. At least one of the said surfaces, e.g. the internal surface (3), is at least partly constituted by a peripheral wall (2) having a front surface facing the operating chamber and a rear surface. The peripheral wall (2) having through-slots (22) which extend parallel to one another and accommodate respective compliant strips (24) extending from the front surface to the rear surface. The strips (22) are retained in the slots (22), against pressure in the operating chamber, by a retaining device such as a clamping member (28). An assembly of three positive displacement machines and engines comprising first and second positive displacement machines are also described.

Abstract: The engine includes a housing having a circular cavity with a rotatable flywheel defining a radially extending power piston(s) disposed therein. An abutment disc connects to a compression piston rotor and rotates synchronously with the flywheel. Compression piston(s) rotate on separate axes within the compression piston rotor and move in and out with respect to the outer periphery of the compression piston rotor. A compression piston stator seals off the top of the compression piston rotor causing the compression pistons to compress a charge of gas to be delivered on top of the power piston(s). Fuel is injected and the combustion zone is ignited. The expanding gases force the power piston(s) and flywheel around the housing producing work. The previous products of combustion are forced out the exhaust system in front of the power piston.

Abstract: An internal combustion rotary power machine which functions in general accordance with the principles of the Carnot heat engine cycle without dependence upon reciprocating pistons, valves or other reciprocating mechanical components for working fluid manipulation. Through elimination reciprocating components the machine potentially offers a large measure of functional excellence in terms power density, efficiency, reliability, mechanical simplicity and production economy. Combustion occurs as a continuously sustained process thereby significantly facilitating the use of gaseous fuel. The machine presented in this disclosure is based on substantial analysis of the functional principles of internal combustion rotary vane machines as related to thermodynamic efficiency, mechanical efficiency, and thermal control considerations. The disclosure demonstrates the integration of primary geometric relationships and technical features necessary to effectively fulfill functional viability requirements.
