Abstract: The integrated electric fuel pump provides at least three sets of four internally threaded bores, one set on one side of the fluid pump housing, a second set oppositely located with respect to the first set, and a third set disposed toward the end of the fluid pump housing. This enables the integrated electric fuel pump to be secured with four threaded members, complete with rubber isolators, and oriented in three ways, two involving a 180° rotation of the fuel pump which will enable the inlet and outlet to change sides. At one end of the fluid pump housing, an electric motor is integrated with the brushes of the motor supported by the integrated pump housing to enable larger brushes and longer urged brush support structures. The metal wall of the housing draws heat from the brushes of the electric motor, and provides spreading and larger surface radiation of the heat along the pump body as well as some heat transfer into the fuel passing within the pump body.

Abstract: A light-weight vacuum pump has a multi-wiper member circular wiper member support and impeller which is eccentrically mounted within a pump housing. The multi wiper member circular support carries from about five to nine wiper members each mounted within a slot extending substantially the length of the support, with each wiper member being centrifically urged outwardly to wipingly engage an inner surface of a round or elliptical walled pump housing. Eccentric action enables the wiper members to be extended to create a large space between adjacent wiper members as an inlet is passed. As the wiper members pass by the inlet, the acentric cylindrical wall of the pump housing begins to compress the wiper members into the support, thereby reducing the space between adjacent wiper members in a compressive manner.
