ROTOR-TYPE INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: engine has case with a three-top space, eccentric shaft received within the space and passing through the center of the case, and oval rotor mounted on the shaft for free rotation. The rotor consists of semi-oval piston and semi-oval gas distributor and has large and small oil rings, face seal over periphery and radial seal made of radial sealing plates set in projections of the space. The engine also has a mechanism for synchronizing planet motion of the rotor and rotation of the eccentric shaft. The mechanism for synchronization is made of an oval synchronizing groove with small radial surface provided on one of the faces of the rotor. The surface is equidistant to the radial surface of the rotor. The mechanism also has tree rollers freely mounted on axles pressed into the face cover for kinematic connection with the rotor groove. The rollers are positioned at beams which are drawn from the case center through radial sealing plates and are positioned at angle 120one relatively another. EFFECT: enhanced efficiency.
