STEAM ROTARY VANED MOTOR Russian patent published in 2013 - IPC F01C1/344 F03C2/30 

FIELD: engines and pumps.

SUBSTANCE: proposed motor comprises fixed hollow housing 1, rotor 3 with four radial slots 4, four vanes 5, steam feed elements 6, Laval nozzles 7, steam discharge elements 8, steam condenser 9, water tank 10, high-pressure steam generator 11, receiver 12 and steam distributor 13 controlled by controller 14. Inner surface 2 of housing 1 is shaped to cylinder. Rotor 3 is shaped to circular cylinder. Vanes 5 are arranged in slots 4 to displace therein and to slide over housing inner surface 2. Steam feed elements 6 are fitted in the housing so that steam fed there through does not create a turbine effect. Laval nozzles 7 are fitted in the housing inclined to rotor radius so that axis of every nozzle is directed tangentially to rotor cylindrical surface. Outlets of condenser 9 are communicated with outlets of steam discharge elements 8. Outlets of steam distributor 13 are communicated with inlets of steam feed elements 6 and outlets of Laval nozzles 7.

EFFECT: higher power at high rpm of rotor.
