DOUBLE-ROTOR COMPRESSOR Russian patent published in 2003 - IPC

FIELD: superchargers for internal combustion engines. SUBSTANCE: double-rotor compressor has housing with inlet and outlet passages where two three-blade rotors are located. Rotors are helical in shape and axes of symmetry of cross section of each rotor at boundaries of flow section of housing are turned relative to each other around axis of rotation of this rotor. Angles of turn of said axes of different rotors lying in one plane are equal in magnitude and opposite in sign. EFFECT: reduced vibro-acoustic activity; enhanced smoothness of gas flow. 3 cl, 2 dwg
