ROTOR-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2009 - IPC F02B53/08 F02B55/14 F01C1/32 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine production. Rotor-piston internal combustion engine comprises housing with working chambers, first and second rotors, combustion chamber, spark plug, vane wheel rotor making a part of the said housing and outer and inner side cheeks. The vane wheel rotor width equals that of the first rotor. The axes of the vane wheel rotor inner and outer cylindrical surface are shifted in opposite direction relative to the engine shaft sense of rotation. Spring-loaded baffle is arranged in the first rotor radial through rectangular slot so that its end face abuts on the vane wheel rotor inner cylindrical surface. The second rotor represents a barrel with its bottom rigidly fitted on the engine shaft. The said barrel features a bulge facing the engine shaft rotation axis and having the width equal to that of the first rotor. Combustion chamber casing is arranged in the hole of the widest vane wheel rotor part. There is an L-like spring-loaded baffle arranged on the barrel surface above the engine combustion chamber and fitted into the second rotor bulge to abut against the vane wheel rotor cylindrical outer surface. Sealing plate is arranged in the vane wheel rotor, nearby combustion chamber, so that its face abuts upon the first rotor cylindrical outer surface. the other sealing plate is mounted in the vane wheel rotor nearby combustion chamber so that its face abuts upon the second rotor bulge inner surface.

EFFECT: easier manufacture, higher engine tightness.
