ABSTRACT:
A rotary internal combustion engine comprising a generally cylindrical stator member having two pairs of sockets located in the periphery thereof, and a rotor member mounted to rotate about the stator member. Two pairs of opposing wedges are pivotally mounted at their vertices on the periphery of the stator member to pivot in and out of respective ones of the sockets as the rotor member is caused to rotate about the stator member. The rotor member has side walls and an interior peripheral wall which, in cooperation with the periphery of the stator member and the two pairs of pivotal wedges, define a combustion cavity and a compression cavity there between. The combustion cavity and compression cavity are disposed on opposite sides of the stator member adjacent the periphery thereof. A cam track is defined in the side walls of the rotor member to guide cam followers extending from the sides of each wedge such that the wedges are caused to pivot in and out of the sockets and to maintain sliding contact with the interior peripheral wall of the rotor member. As the rotor member rotates and the wedges pivot in and out of the sockets, the compression cavity and the combustion cavity successively increase and decrease. A fuel mixture is introduced into the compression cavity as it enlarges. As the rotor member continues to rotate, this cavity and the fuel mixture therein is compressed. The fuel mixture is ignited at or just prior to the time the mixture is fully compressed, to achieve high power efficiency. Igniting the fuel mixture causes the rotation by creating unbalanced tangential components of pressure upon inclined portions of the interior peripheral wall of the rotor member. Shortly after combustion of the fuel mixture, the combustion products are exhausted from the combustion chamber. The compression and the combustion of the fuel mixture always occurs between the opposing bases of the wedges, which bases are each configured to direct the pressure force to a pivotal pin at the opposite vertex of each wedge. Thus, all bending stresses and flexural deformations of the wedges are virtually prevented, thus substantially eliminating the traditional major problem of vane wear and distortion in rotary engine design.
