ABSTRACT:
A high pressure pump including a cylindrical rotor carried within a cylindrical cavity provided in a housing. Inlet and outlet ports are provided for transporting fluid to and from the cavity. A plurality of circumferentially spaced concave semicircular chambers are provided on the periphery of the rotor. A pivotal member is carried closely adjacent the outlet port and rides along the curving wall of the chambers as the chambers pass the outlet port directing fluid transported in the chambers to the outlet port. The rotor is driven by an electric motor. A bypass valve is provided between the outlet and inlet ports for bypassing the flow of fluid therebetween when an obstruction appears in the outlet or when the pressure exceeds a predetermined value.
