ンプ。An eccentric rotor that is eccentric to the casing is installed in a casing, and sealing rings that are coaxial with the inside of the casing are rotatably incorporated on both sides of the rotor, and a plurality of sealing rings are formed in a radial arrangement around the outer circumference of the eccentric rotor. In the recessed part of
A valve plate is assembled so as to be movable in the radial direction of the eccentric rotor, and a shaft provided at both ends of the valve plate is supported by sealing rings on both sides so that the outer end of each valve plate is in contact with the inner peripheral surface of the casing. The sealing rings on both sides are provided with radial cut-off portions that provide elasticity to allow the ring to change in diameter, and the depth of the inner diameter hole of the sealing ring and the concave notch of the eccentric rotor is adjusted according to the suction process. The inner and outer ends of each valve plate are each formed into a curved surface that bulges outward with a curvature that matches the inner peripheral surface of the casing.
