ROTARY COMPRESSOR Russian patent published in 1998 - IPC

FIELD: mechanical engineering; compressor for operation with internal combustion engine. SUBSTANCE: compressor has cylindrical stator and rotor installed on shaft in start stator to form suction and compression chambers, and air conduits. Stator has door separating suction chambers from compression chambers and installed on axle of rotation which, in its turn, is installed on generating line of stator cylindrical surface. Lever is secured on end of door axle at an angle to axle. Template made in the form of eccentric disc is secured on rotor shaft in crankcase box. Roller is installed for contact with cylindrical surface of disc on end of lever. Spring presses roller to disc. Air conduit through which atmospheric air or gas is delivered into suction chamber and provided with port overlapped by cylindrical bridges and compressed air or gas outlet conduit from compression chamber are installed at sides of axle of rotation of stator door. Compressed air or gas outlet conduit is overlapped by spring-loaded door with axle of rotation parallel to axle of rotation of stator door. Rotor shaft has channel with holes to pass cooling air through rotor. Rotor is made hollow and is installed eccentrically in stator. Several rotors can be installed in stator on one shaft. EFFECT: increased efficiency of compressor and rotary internal combustion engine. 4 cl, 8 dwg
