Abstract: A rotary engine has a rotor with a rotor pocket for receiving air-fuel mixture that is combusted therein to propel the rotor within the housing. The rotary engine may have one or more intake spray injectors that spray fuel into the rotor pocket and onto the rotor face within the intake chamber to effectively cool the rotor pocket and rotor face. An air channel extension of the rotor pocket may be configured in the housing and/or in the rotor to extend from the compression chamber into the ignition-combustion chamber to relieve some pressure in the trailing compression chamber of a rotor face to minimize negative work. A supplemental air-fuel conduit may be configured to supply high-pressure gas from the compression chamber to an ignition injector(s). A thrust nozzle may be configured within the rotor pocket to direct combustion gases therethrough to propel the rotor and increase efficiency.

Abstract: A rotor mechanism for use in moving fluid. The rotor mechanism has six rotor units spherically arranged, with at least one rotor unit including a port through it's body. Each rotor has the form of a truncated cone with two symmetric spiral recesses provided on the lateral surface of the rotor which acts to cooperate with the adjacent rotors. Rotation of at least one rotor unit causes rotation of adjacent rotor units which thereby moves fluid without compression between the outside of the mechanism and the port via a central substantially spherical free space cavity formed by the cooperation of inner surfaces of the rotor units. The rotor mechanism is fully submersible.

Abstract: An internal combustion rotary engine has a chamber defined by a chamber wall and a rotor valve body in three locus-sealing contact with the chamber wall to define a series of three subchambers including a first subchamber for sequential compression, transfer, and combustion of a fuel mixture from a chamber fuel mixture intake and for exhausting combustion products through a chamber exhaust outlet. The rotor body defines a first bodily internal path for fuel mixture travel from the intake to the first subchamber for compression and combustion to combustion products, and a second bodily internal exhaust travel path between the combustion products in the first subchamber and the chamber exhaust outlet for exhausting of the combustion products. The chamber and rotor cooperate to transfer compressed fuel mixture past the rotor within the first subchamber. The rotor further defines a sealing and sliding valve structure with the chamber wall for controlling intake into and exhaust from the first subchamber.

Abstract: A rotary engine includes a rotor having one or more combustion chambers connected to an exhaust passageway extending radially outward from the combustion chamber to an exhaust port adjacent a peripheral edge of the rotor. The exhaust gas is expelled at an angle to thereby generate cause the rotor to rotate. The housing may include reflective surfaces that reflect shockwaves from the exhaust gas back towards vanes on the rotor to thereby capture additional energy from the exhaust gas. The housing may also include stators that capture additional energy from the exhaust gas and rotate the rotor. An intake port fluidly connected to the combustion chamber is aligned with an opening in the housing as the rotor rotates to thereby allow comprised air to flow into the combustion chamber. As the combustion chamber rotates, it is closed off by a closed portion of the housing, fuel is injected, and ignited, to thereby generate exhaust gases and generate power.

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.
