Abstract

The present invention relates to a rotor swivel type pump, mainly includes a main pump body, a rotor, a main shaft and a slide pin; wherein a round cylinder chamber is formed in the main body, the rotor is a substantially-round plate member installed in the cylinder chamber, the outer periphery of the rotor is in close contact with the inner wall of the cylinder chamber, the main shaft is eccentrically installed with a driving wheel which is pivoted to an eccentric portion of the rotor, so as to drive the rotor to perform a swivel movement; the main shaft passes through the main body and protrudes to the exterior; the interior of the main body is formed with a room in which the slide pin is pivotally installed, one end of the slide pin forms a first surface perpendicular to the axle direction of the slide pin, the outer periphery of the rotor forms a second surface in close contact with the first surface, so that the rotor can swivel in a circulation route in a revolution mode. The main body is formed with an inlet and an outlet, one end of the inlet and the outlet are connected with the cylinder chamber, the other ends are connected with the exterior; an sucking portion and an exhaust portion, respectively in communicate with the inlet and the outlet, are defined in the cylinder chamber through the slide pin and the rotor, so the fluid can be introduced into and exhaust out of the chamber for pumping the fluid.
