SYSTEM FOR SEALING ROTOR-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: system has at least two sealing members received in grooves of one of the mated surfaces of the housing and rotor for permitting the contact with the other surface and made up as plates having rounded contact surfaces. The surfaces has different rigidity and positioned perpendicular to the direction of motion of the mated surfaces. The rigidity of the rounded contact surface of one of the plates exceeds the rigidity of the other mated surface. The rigidity of the contact surface of the other plates is less than the rigidity of the other surface mated with them. The first surface can be made on the rotor, the second surface can be made on the housing, and vice versa. EFFECT: enhanced reliability. 3 cl, 6 dwg, 1 tbl
