摘要： 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.

摘要： An in-tank fuel supply unit self cleans the mesh filter of the primary fuel pump, thereby permitting smaller mesh sizes to decrease pump wear and increase the life of the pump. Generally, the in-tank fuel supply unit includes a reservoir, an auxiliary fuel pump, a primary fuel pump and a filter. Fuel exiting the auxiliary fuel pump outlet is directed towards the filter to wash debris from the filter. Preferably a swirling flow is generated within the reservoir, or the system in run in an overflow condition to assist in the self cleaning of the fuel filter.

摘要： A fuel pump includes a housing, and a motor. An impeller has first and second impeller flow channels having a plurality of vanes positioned therein. The impeller defines a flow passageway extending through the impeller. A cover is attached to the housing and defines a cover flow channel. The cover flow channel receives fuel from an inlet formed in the cover. A first portion of the cover flow channel is aligned with the first impeller flow channel and a second portion of the cover flow channel is aligned with the second impeller flow channel. The cover flow channel extends around the cover more than 360 degrees. A body is positioned within the housing and defines an impeller chamber, sized to receive the impeller, and an outlet passageway is positioned to fluidically connect to the flow passageway of the impeller to receive higher pressure fuel for delivery to the engine.

摘要： 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.

摘要： 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.

摘要： A pressure regulated valve is provided for a mechanical returnless fuel system for an automotive vehicle that includes a fuel pump for supplying fuel from a fuel supply to an engine. The pressure regulating valve includes a conduit in fluid communication with the pump outlet. The valve includes a valve seat and a valve body having a frustoconical seal surface. A spring biases the valve body to close the valve body against the valve seat. During operation, increased fuel pressure from the pump opens the valve body to discharge excess fuel to the fuel supply.

摘要： A mechanical returnless fuel system comprises a fuel pump having an output for supplying fuel to fuel injectors of an automotive engine. The fuel system includes a pressure regulating valve that returns a portion of the pump output in excess of engine fuel usage to the fuel supply. The pressure regulating valve results in a fuel pressure that varies as a function of engine fuel demand. During operation, a controller determines a projected engine fuel demand, then determines an estimated fuel pressure based upon the projected engine fuel demand. The controller utilizes the estimated fuel pressure to provide a more accurate calculation of the opening time for the fuel injectors and thereby improve engine control.

摘要： A low deviation pressure relief valve for a fuel pump consisting of a housing having an elongated bore having a continuous wall, an axis, shoulders arranged on the wall so as to extend toward the axis. A ball in the housing has a diameter at least less than the diameter of the bore and a ball retainer located in the bore upstream from the shoulders forms a ball seat by pre-coining process. The ball is smaller than the retainer seat in diameter to ensure an edge seal with the ball. A spring coaxial with the axis located down stream from the ball retainer and supported on the shoulders, and the ball is located between the spring and the ball seat wherein low flow restriction is created and reduced pressure variation is created as fluid flows past the ball and less buckling in the spring is created by guide ribs.
