Abstract: An in-tank fuel supply unit is provided for supplying fuel from a fuel tank to an engine. The fuel supply unit generally comprises a fuel delivery module and a jet pump assembly selectively attachable to the fuel delivery module. The fuel delivery module has a housing defining a reservoir and includes a fuel pump for pressurizing fuel in the reservoir. The jet pump assembly has a suction tube defining a suction chamber and a nozzle situated inside the suction chamber. The nozzle receives pressurized fuel from the fuel pump and sprays the fuel from a nozzle tip at high velocity to draw additional fuel into the suction chamber through an inlet formed in the suction tube.

Abstract: 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.

Abstract: The present invention provides a system for controlling speed of the fuel pump. The system includes a fuel pump, a controller, and a field modification module. The fuel pump is configured to receive a driving signal causing the fuel pump to pump fuel. The controller is configured to determine a desired fuel pump speed and generate a control signal based on the desired fuel pump speed. The field modification module is located proximate the fuel pump and is in communication with the controller to receive the control signal. The field modification module generates a flux in response the control signal thereby controlling speed and torque of the fuel pump.
