发明名称 Vacuum pumps
摘要 A rotary pump comprising a stator body having a bore and a rotor assembly mounted eccentrically in the bore to form a cavity between the stator body and the rotor assembly. The rotor assembly has two blades slidably positioned in diametrically opposed slots in the rotor assembly. In use of the pump the two blades are substantially in contact with an inner wall of the stator body. The stator body has an inlet and an outlet to allow, in use of the pump, fluid being pumped to enter into and be expelled from the cavity by means of the rotating vanes. The rotor assembly is of integral construction with each slot defined therein having an arcuate base and each blade has an end portion substantially conforming to the arcuate slot base.
