FIELD: engines and pumps.
SUBSTANCE: proposed engine comprises cylindrical stator with covers accommodating offset cylindrical rotor. Stator covers accommodate slip covers to vary compression ratio that may displace in guides parallel with straight line connecting geometrical axes of stator and rotor. Said slip covers are fitted with rotor shaft bearings and fixed contacts of ignition plugs. Front slip cover incorporates additionally fixed gear of valve timing mechanism drive. Rotor has odd number of sector-shape working chambers equal to at least three. Rotor faces are tightly closed by disc shaft-covers with ignition plugs fitted therein. Every working chamber houses working member of identical sizes and shapes to make a limited turn about axis extending through working chamber sector vertex and oriented along rotor generatrix. Working member outer side stay in contact with intermediate cylinder via pin. Bearing pin cantilever ends are fitted to displace freely along the circle on face guide grooves of intermediate cylinder. Intermediate cylinder is fitted into stator to rotate unobstructed about common geometrical axis.
EFFECT: higher efficiency and reliability.
