Abstract
Abstract A rotary engine and compressor constructed in elongated configuration around a central shaft to which vanes are rotatibly secured. The vanes project through slots in a cylindrical rotor mounted off-center on bearings in a casing. The cylindrical rotor is the primary rotating member which drives through gear means the accessory shaft and the power hub. As the rotor and vanes revolve in the casing, the volume between the vanes varies from near zero at the tangent point to a maximum at 180* opposite the tangent point. Selected porting and venting of the casing cause the rotating cylinder and vanes to function as either an engine when fuel and ignition is provided or as a compressor when driven in rotation.
