ABSTRACT:
A multi-chambered self-priming rotary pump having a pair of eccentric cams, each in contact with opposite sides of a rotor plate at one point and positioned 180.degree. out of phase so that the convex side of one cam is in direct opposition to a concave side of the other cam. At one point of contact on the convex curves, the cams bear against the side surfaces of the rotor which in turn forms a running seal with the bore of a housing to define two symmetrical enclosures at each side of the rotor. During rotation, a split core closure valve reciprocates between the surfaces of the cams and in so doing, the closure valve functions to produce an area of compression to the front of its travel with an area of vacuum to the rear of its travel. As one chamber phases out of cycle, its counterpart is producing maximum outputs. During rotation, a rotor impeller duct functions to pressure load the closure valve and provide impetus to the injection (clockwise rotation) or ejection (counterclockwise rotation) of pump fluids. The impeller duct is in communication with an annular housing duct which communicates with a housing fitting orifice. Completing the fluids cycle are shaft ports in communication with a ducted shaft which in turn communicates with a cam fitting orifice.
