Claims

[Scope of Claim for Utility Model Registration] A rotor that is pivotally supported by a drive shaft and has a substantially elliptical shape with the drive shaft as the center, and each vertex in the longitudinal direction of the rotating rotor with the rotor disposed inside. A circular rotor chamber with an inner wall that is in close contact with each other, an auxiliary chamber facing the rotor chamber, an intake port communicating with one side of the auxiliary chamber, a discharge port communicating with the other side of the auxiliary chamber, and an auxiliary chamber. It is arranged in contact with the wall of the auxiliary chamber so that the suction port side and the discharge port side are isolated indoors.
and a contactor that comes into contact with the rotor rotating in the rotor chamber, wherein the contactor is approximately circular so as to be able to rotate in contact with the rotor, and the rotating contactor is connected to the rotor and the interior of the auxiliary chamber. A rotary pump with a positioning body placed inside the auxiliary chamber to regulate its position so that it is always in contact with the body.
