Abstract:
1. A rotary engine providing internal combustion of a fuel, said rotary engine comprising: a housing having a sidewall, an inside surface of said sidewall having a plurality of lobes, adjacent ones of said at least two lobes are separated by a peak; a rotor having a shaft and at least one circular cutout region, said rotor rotatable within said housing, said rotor forming a seal with each said peak intermittently when said rotor rotates within said housing, said rotor having a first top-dead-center position and a second top-dead-center position; and at least one rotating member, each of said at least one rotating member rotatable within a corresponding one of said at least one circular cutout region in said rotor, each said rotating member having a plurality of tips equally spaced around said at least one rotating member, at least one of said plurality of tips contacting one of said plurality of lobes as said rotor rotates within said housing, adjacent ones of said plurality of tips separated by a side surface, a trailing one of said side surface forming a combustion chamber when said adjacent ones of said plurality of tips contact said inside surface of said housing, said trailing one of said side surfaces sequentially performing a power cycle and at least a portion of an exhaust cycle and a leading one of said side surfaces sequentially performing at least a portion of an intake cycle and a compression cycle when said rotor rotates through an angle equal to an angular separation from said first top-dead-center position to said second top-dead-center position.
