ROTARY MACHINE Russian patent published in 2007 - IPC F01C1/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to rotary machines which can be used as engines, pneumatic or hydraulic machines. Proposed rotary machine has rotor block housing accommodating synchronously rotating rotors coupled by gear wheels providing relative transmission of rotor torques. Machine is provided with inner vertical and horizontal partitions with variable thickness walls forming, together with walls of block housing, cylindrical spaces for rotors. One turnable nozzle set is installed inside rotor block, set being made in form of cylinder with branch pipe and cutouts in sides of set housing. Torque from rotors to power takeoff shaft is transmitted through drive gears installed on ends of diagonally opposite shafts and flywheel with internal gear rim. Rotors are made in form of curved blade wheels.

EFFECT: reduced overall dimensions of machine, reduced consumption of working medium, simplified technology of production and assembling.
