Abstract A rotary engine which may be driven by pressure fluid such as compressed air, steam or hydraulic fluid under pressure comprising an integral rotor rotatably mounted in a housing. The rotor has forward and reverse vanes machined or cast thereon, which vanes are uniform in depth from the ends of the rotor to the center thereof where they terminate. Appropriate grooves are formed in the wall of the housing to admit fluid under pressure to the forward and reverse ends thereof, and an exhaust groove is formed in the wall of the housing running the full length thereof to provide a common exhaust groove for the fluid admitted to both the forward and reverse ends of the rotor. An accelerator valve is provided for regulating the admission of pressure fluid, and a forward and reverse valve is provided between the accelerator valve and the housing which may be actuated by an appropriate lever or petal to direct the pressure fluid to either the forward or reverse end of the rotor.
In a rotary engine, a housing having a cylindrical bore therein; a rotor rotatably disposed in the cylindrical bore; a continuous cylindrical ring provided about the rotor centrally thereof in the bore; a plurality of equally spaced spiral vanes provided on opposite ends of the rotor and terminating at said ring; said vanes on opposite ends having oppositely facing faces thereon; a first groove formed in the surface of the bore terminating adjacent the ring and communicating with one end of the rotor; a passage in the wall of the housing extending longitudinally thereof and terminating adjacent the other side of the ring and being circumferentially spaced from the first groove; a second groove in the surface of the bore communicating with the passage terminating adjacent the said other side of the ring and communicating with the other end of the rotor; a common discharge channel extending longitudinally the full length the inner surface of the bore in communication with both ends of the rotor and being spaced circumferentially from the first and second grooves; and valve means selectively positionable to admit fluid either to the first or second groove.

The combination called for in claim 7 wherein the first and second grooves are diametrically spaced on opposite sides of the bore, the discharge channel is spaced 90* from the grooves, and the vanes are so spaced on the rotor that as a vane comes into communication with a groove the adjacent vane in the direction of rotation of the rotor moves into communication with the discharge channel.
