Abstract
An engine including a housing formed with a pair of side-by-side intersecting substantially cylindrical cavities, and a pair of counter-rotating power rotors rotatably mounted within the cavities. The pair of power rotors include intermeshing lobes that each define open ended combustion chambers.
Claims37
An engine comprising:
- a housing including a pair of end walls and a pair of intersecting parallel cylinder walls having inner wall surfaces that define first and second interconnected cylindrical cavities, the intersecting cylinder walls forming spaced-apart parallel first and second edges;
- first and second shafts extending coaxially in the cavities and supported for rotation at the end walls;
- and
- first and second rotors secured to said first and second shafts for rotation in the respective cavities, the first and second rotors each having a plurality of radially extending lobes with outer ends, each lobe defining a combustion chamber that opens at the lobe outer end.

In an engine of the type including a housing defining a pair of parallel, intersecting cylinders, and a pair of rotors affixed to parallel shafts extending coaxially in said cylinders, each rotor having a plurality of lobes, the rotors being positioned, so that their lobes intermesh;
- the improvement comprising:
- wherein each lobe of each rotor defines an open-ended combustion chamber.
An engine comprising:
- a housing formed with a pair of side-by-side intersecting substantially cylindrical cavities;
- a pair of counter-rotating power rotors rotatably mounted in the cavities, the pair of power rotors including intermeshing lobes each defining open ended combustion chambers;
- at least two exhaust ports formed in the housing in fluid communication with the pair of cavities;
- an ignition device in communication with the cavities;
- first and second fuel intake ports disposed in the housing and connected in fluid communication with the cavities;
- and
- first and second air intake ports disposed in the housing and connected in fluid communication with the cavities.

An engine comprising:
- a housing defining parallel cylindrically shaped intersecting cavities;
- a pair of parallel shafts rotatably mounted within the cavities, the pair of parallel shafts extending outside the housing to form at least one drive shaft;
- and
- first and second intermeshing rotors rotatably mounted within the housing, each rotor configured with a central hub portion coupled to one of the shafts for rotation therewith and a number of radially outward extending lobes defining open ended combustion chambers.

An engine comprising:
- a housing formed with a pair of side-by-side intersecting substantially cylindrical cavities;
- a pair of counter-rotating power rotors rotatably mounted in the cavities, the pair of power rotors including intermeshing lobes each defining open ended combustion chambers;
- first and second intake ports formed in the housing and connected in fluid communication with the cavities and a source of air for injecting air to each combustion chamber;
- third and fourth intake ports formed in the housing and connected in fluid communication with the cavities and a source of fuel for injecting fuel into each air filled combustion chamber to form an air/fuel mixture;
- an ignition device coupled to the housing and substantially aligned with a respective combustion chamber when the rotor lobes are fully intermeshed, the ignition device adapted to ignite the air/fuel mixture within the aligned combustion chamber, and whereby the combusted gases resulting from the ignition of the air/fuel mixture act upon the lobes to rotate the rotors;
- and
- at least two exhaust ports formed in the housing in fluid communication with the pair of cavities, wherein the combusted gases will subsequently escape through the exhaust ports by further rotor rotation.
