Abstract
A rotary piston machine includes a casing and a rotor assembly, each with a hypotrochoidal. The rotor assembly includes apices that conform to the hypotrochoidal profile of the casing, and the relative motion of the casing and the rotor assembly create variable volumes. The variable volume allows the rotary piston machine to function as a compressor, an expander, an internal combustion engine, a positive displacement pump, or a fluid-driven motor.
Claims11
A rotary piston machine, comprising:
- a casing with a hypotrochoidal profile;
- a rotor assembly including a profile conforming to the hypotrochoidal profile of the casing;
- wherein the rotor assembly has apices which conform to the hypotrochoidal profile of the casing, the apices having a leaning angle in a range of ±45 degrees;
- wherein a relative motion of the casing and the rotor assembly creates variable volumes;
- and
- wherein a plurality of rotary valves on the hypotrochoidal profile of the casing, opening and closing a plurality of associated ports into the variable volume at predetermined intervals allows the rotary piston machine to function as a compressor, an expander, an internal combustion engine or a positive displacement pump or fluid driven motor.
