FIELD: mechanical engineering. SUBSTANCE: engine consists of housing 27 and cylinders 18,19 rotating inside the housing about cylindrical shaft 5. The cylinders have outlet ports 20 made up as jet nozzles and turbine 33. Pistons 1 are received in cylinders 18,19 for permitting reciprocation together with ball chambers 10,15 and jet nozzles 11,16. The nozzles have inclined ring grooves 3,4 at their skirts. The skirts are in contact with bearings 25 fitted on the pins secured in the housing. Pistons 1,2 are fixed against rotation about shaft 5 by way of balls 24 rolling up over the longitudinal grooves of the shaft and pistons. Exhaust gases are used in the engine due to introducing portions of water which is converted into vapor. Shock waves exerted by pressure pulses are used. EFFECT: enhanced efficiency. 6 dwg
