FIELD: engines and pumps.
SUBSTANCE: rotary piston engine comprises housing with cylindrical working chamber and separators of suction and delivery chambers, flexible impeller-piston and wave generator. Separators of suction and delivery chambers represent two-tab spring-loaded counter-flap hinges arranged inside said housing to allow independent rotation of said tabs about common rotational axis that are buried flush with working chamber surface in appropriate recesses on passing of flexible impeller-piston strain wave apices.
EFFECT: increased tightness, reduced radial sizes and preventing jamming.
