A fuel pump is provided having improved efficiency by lowering the wet circle index of the pump while maintaining robust axial clearances to meet the demands of an automotive application. One embodiment includes a fuel pump for pressurizing fuel for delivery to an engine of a motor vehicle. The fuel pump generally comprises a housing, a motor, a single sided impeller, a cover and a body. The provision of a single sided impeller greatly reduces the wet circle index and improves the pump efficiency. The cover, impeller, and body are structured to axially balance the impeller which is free floating on the shaft of the motor.

The present invention provides a system for controlling the speed of a motor by altering the magnetic field of the motor. The system includes field modification module, and a motor having field windings and a rotor. The field windings are configured to receive a driving signal that generates a magnetic field causing a rotation of the rotor. The field modification module is proximate the motor and alters the magnetic field in response to an input signal thereby controlling the speed and torque of the rotor.

A fuel pump includes a housing, and a motor. A single sided impeller has first and second impeller flow channels each including a plurality of vanes. The impeller defines a flow passageway extending therethrough. A cover is attached to the housing and has a cover surface that defines first and second cover flow channels. The cover flow channels receive fuel from inlets formed in the cover. The first and second cover flow channels are aligned with the first and second impeller flow channels and receive fuel through the inlets and deliver fuel to outlets. A body is positioned within the housing and defines an impeller chamber to receive the impeller, and a first outlet passageway fluidically connected to the first cover flow channel and impeller flow channel. A second outlet passageway formed within the cover is fluidically connected to the second cover flow channel and impeller flow channel.

The present invention involves a gear assembly of a fuel pump for improved supply of fuel to an automotive engine from a fuel tank. The assembly includes an inner gear and an outer gear matingly cooperating with the inner gear for rotation about an axis. The assembly further includes a pump cover including a cover surface adjacent the inner and outer gears and a pump body including a body surface adjacent the inner and outer gears opposite the pump cover. The cover surface has a primary inlet porting and a secondary outlet porting formed thereon and separated between seal areas. The body surface of the pump body includes a primary outlet porting and a secondary inlet porting separated between seal areas. In use, the inlet portings and the outlet portings of the pump body and the pump cover cooperate together, respectively, such that fuel entering through the inlet portings pass therethrough at a rate at which the gear assembly moves. Also, the outlet portings of the pump body and the pump cover cooperate together to allow fuel to pass therethrough at the rate at which the gear assembly moves.

A regenerative pump for an automotive fuel pump assembly comprises a cover and body that define a chamber and a ring impeller disposed within the chamber. An inlet is formed in the cover, and a discharge port is formed in the body. The body includes a pumping channel adjacent the chamber and having a discharge end section extending from the discharge port. The port diameter is greater than the radial width of the discharge end section. Also, the discharge end section has a depth that progressively increases adjacent the discharge port. The configuration of the discharge port and the channel end section reduces frictional and turbulent losses and thereby improves pumping efficiency.
