FIELD: engines and pumps.
SUBSTANCE: proposed engine incorporates two-lever rotary pistons 6, 7 fitted in housing 1. Every rotary piston comprises two pistons 13, 15 and 16. At least two of said three pistons accommodate guide elements engaging with one guide groove 26 made in housing 1 to control rotary motions. Said guide elements represent free balls 27. Every of at least two aforesaid pistons have guide cup to receive one of said balls. Appropriate guide cups communicate with lubricant feed channel made in piston 13, 15, 16 via orifice. Said balls 27 can have spherical shape. Said guide cups can represent, in fact, semi-spheres. Guide groove can feature, in fact, semi-circular profile. Said ball can have, in fact, ellipsoidal shape. Said guide cups can represent, in fact, semi-ellipsoidal shape. Guide groove can feature, in fact, semi-ellipsoidal shape.
EFFECT: reduced costs, higher operating performances and simplified design.
