摘要： An oil seal assembly is provided for a rotary engine in which an annular groove is formed in the side of the engine rotor with an oil seal ring being fitted within said annular groove. The oil seal ring is pressed against the side wall of the engine housing by annular spring means, and detent means are inserted between the ends of the annular spring means, the detent means being engaged in recesses carved in the innermost wall of the oil seal ring and in the bottom wall of the annular groove of the rotor to restrain relative motion therebetween during rotation of the rotor.
