ABSTRACT:
A circular rotary engine comprises a housing having spaced concentric cylindrical walls defining an annulus therebetween with intake and exhaust ports through the sides of the walls and a cylindrical rotary piston ring having multiple symmetrically undulating surfaces on both ends and coaxial interior and exterior gears for shaft drive which rotates within the annulus while reciprocating between end ring members positioned within the annulus and secured at each end of the interior and exterior walls. The end rings have opposite facing undulating frontal surfaces symmetrical with the undulating frontal surface of the rotary piston such that the piston ring surfaces cooperate with the end ring surfaces to alternately create a volume area and displace the volume area in some portion during rotation, thus alternately opening a series of chambers on one end of the rotary piston while displacing chambers on the opposite end with the reciprocating movement during axial rotation of the rotary piston responding in motion against the symmetric frontal surfaces of the end rings. This motion is accomplished while maintaining frontal surface contact at all times, without restriction to rotation whereby frontal surface seal contact is maintained during axial reciprocation and rotary movement. All components are coaxial thus providing the rotary piston with controlled circular axial rotation within the annulus with the end ring members controlling reciprocation.
