This compressor rotor shaft by synchronized gears remain engaged so that the two rotors. The rotor and the cylinder inner wall surface of each concave portion of the working volume of the composition, during the rotation of the rotor away from the gas suction port, when moved to the vicinity of the exhaust port and an exhaust port communicating instantaneously, due to higher pressure gas reflux, then the pressure in the working volume suddenly increased, then the gas is supplied to the exhaust passage. Two rotors alternately work. Two rotors do not touch, the gap between them, tightly controlled by a seal, so the exhaust gas from oil pollution. Shandong centrifugal fan manufacturers _ Shandong simple centrifugal blower fan manufacturers such structure, convenient, suitable for low pressure gas delivery and pressurized situations, also be used as a vacuum pump.
