Abstract: A rotary compressor for compressing a working fluid includes a housing having an oil sump. A stationary shaft extends into the housing and includes a longitudinal passage. The longitudinal passage has an oil inlet in fluid communication with the oil sump. A working fluid inlet receives the working fluid. A motor has a stator and a rotor. The rotor is rotatably mounted on the shaft within the housing and includes an internal compression chamber in fluid communication with the longitudinal passage. A roller is rotatably mounted on the shaft and eccentrically disposed within the compression chamber. The roller is coupled to the rotor such that rotation of the rotor rotates the roller and thereby compresses the working fluid within the compression chamber.

Abstract: An object of this invention is to prevent drop of life of a bearing by an axial force when using a pump as a compressor. In a vacuum pump 1 compressing and discharging gas in a direction of a rotor axis by rotation of screw rotors 3, 4 engaged together which are supported rotatably in a casing 2, balance pistons 13, 14 are disposed on shafts 6, 7 of said screw rotors at inlet side of said casing. The balance pistons separate a receiving section 17 at area of the screw rotor and a pressurizing section 16 at area of the balance piston, and a thrust force of the screw rotors at a pressurizing condition is canceled by acting the discharge pressure in the pressurizing section. The pump is used as a compressor when the discharge pressure is acted on the balance pistons 13, 14. When the pump is used as a vacuum pump, air at discharge side is sucked as cool air through a cooler toward a place near to the discharge side of the receiving section 17 at area of the screw rotor.
