ABSTRACT:
A rotary type internal combustion engine including an outer housing in which a rotor is rotatably mounted, the rotor having at least one pocket formed in the periphery and in which combustion gases expand to drive the rotor. A oscillating member is mounted in an inner circumferential wall of the housing and engages the outer periphery of the rotor and enters the pocket as it passes, the oscillating member being hollow and co-operating with a stationary inner piston to form an expandable combustion chamber into which is admitted a fuel mixture for ignition by ignition means. The oscillating member has an outlet which permits most of the combustion gases to escape from the combustion chamber into the pocket of the rotor to provide a force between the reciprocating member and a leading surface of the pocket for driving the rotor. The presence of the combustion chamber provides for more effective combustion of the fuel mixture by allowing for a better control of the fuel mixture into the combustion chamber and a timed ignition which can be in advance of that which is possible in known rotary engines.
