Title: Rotary engine

Abstract: A rotary internal combustion engine having an ellipsoidal wall member which forms an ellipsoidal internal chamber. A drive shaft is rotatably mounted in the housing and extends transversely through the ellipsoidal chamber. A substantially cylindrical rotor is secured to the drive shaft within the chamber and has a plurality of circumferentially equidistantly spaced vane members radially slidably disposed within the rotor. A source of fluid pressure communicates with the radially inner end of the vane members to urge the vane members radially outwardly so that the vane members contact selected circumferential sections of the wall portion. A fuel supply means including a rotary compressor supplies a fuel and air mixture to the rotor which thereafter further compresses the fuel between the rotor, the wall portion, and adjacent vane members. The fuel air mixture is ignited by appropriate ignition means to thereby rotatably drive the drive shaft.
