Filed:

Jun 28, 2005

Appl. No.:

11/168912

Inventors:

Bobbie Watkins, legal representative - Harriman TN, US
Lawrence A. Hendrix - Knoxville TN, US
Barton W. Watkins - Knoxville TN, US

Assignee:

Power Source Technologies, Inc. - Knoxville TN

International Classification:

F02B 53/00
F01C 1/00

US Classification:

123241, 123246, 418225, 418227

Abstract:

An apparatus for a rotary internal combustion engine. The engine has three rotating members that orbit about the center of a three-armed rotor as the rotor rotates within a housing with three lobes. The tips of the rotating members engage the lobes and a circular cutout in the rotor () as the rotor rotates. A back plate includes inlet and exhaust ports that are sequentially opened and closed by the rotating members and rotor as they move within the housing. A front plate rotates with the rotor and separates the combustion chambers from a planetary gear assembly that ensures the alignment of the rotating members as they orbit the rotor shaft. Fuel is injected after the compression cycle is initiated.

Abstract:

An apparatus for an aspiration plate for a rotary internal combustion engine. The engine has three rotating members that orbit about the center of a three-armed rotor as the rotor rotates within a housing with three lobes. The tips of the rotating members engage the lobes and a circular cutout in the rotor as the rotor rotates. A back, or aspiration, plate includes inlet and exhaust ports that are sequentially opened and closed by the rotating members and rotor as they move within the housing. A front plate rotates with the rotor and separates the combustion chambers from a planetary gear assembly that ensures the alignment of the rotating members as they orbit the rotor shaft. Fuel is injected after the compression cycle is initiated.

US Classification:

123241, 123246, 123205, 418 612, 418227, 418225

Abstract:

An apparatus for facilitating combustion in a rotary engine with planetary rotors orbiting inside a housing containing a main rotor. In various embodiments, the planetary rotor has a multi-faceted face that engages a bridge during the transition from the compression cycle to the combustion cycle with the bridge and face forming a dynamic seal; the planetary rotor has a face engaging a bridge during the transition from the compression cycle to the combustion cycle such that the bridge and face have a gap that allows gas flow from the trailing volume to the leading volume and the gap is sufficiently small to quench flame propagation from the leading volume to the trailing volume; and/or the face of the planetary rotor opposite a fuel injector has a pocket that allows the fuel cloud to expand without impinging or wetting the face of the planetary rotor.
