Abstract: A grounding arrangement for an in-tank fuel system includes a fuel level sensor assembly of a fuel module comprising a conductive card body and a resister card supported on the conductive card body. The resister card includes a conductive trace in conductive contact with the conductive card body. The card body is conductively connected to a conductive fuel module component. The trace is adapted to be connected to the ground plane of a vehicle. Other traces on the resister card are in the electrical circuit of the fuel level sensor assembly. The fuel module further includes a conductive blade having a knife edge and in conductive contact with a conductive fuel module component. The knife edge cuts through the insulation of an insulated conductor to allow the knife edge to be in contact with the conductive element of the conductor.

Abstract: A valve assembly includes a housing having a valve seat defining at least part of a vent passage, a pressure responsive member carried by the housing and defining at least part of a pressure chamber, and a valve carried by the housing and having a closure moveable relative to the valve seat between an open position permitting fluid flow through the vent passage and a closed position at least substantially restricting fluid flow through the vent passage. The closure is moved by the pressure responsive member in response to changes in pressure in the pressure chamber. A control passage communicates at one end with a pressure source and at its other end with the pressure chamber and an electrically operated valve is moveable from a first position permitting a pressure signal to develop within the pressure chamber and a second position permitting pressure within the pressure chamber to vent.

Abstract: A fuel pump system includes a fuel pump having a direct current motor for driving a pumping element to deliver fuel to an engine at a variable rate. A pulse width modulated controller is electrically communicated with the motor for varying the speed thereof, thereby enabling the fuel pump to deliver the fuel to the engine at the variable rate. The controller includes a first switch in series with the motor and a second switch in parallel across the motor. In a motor-off cycle, control electronics connected to the switches deactivate the first switch and activate the second switch to commutate the motor. In a motor-on cycle, the control electronics deactivate the second switch and activate the first switch to power the motor.

Abstract: A fuel system with a fuel tank having at least one opening into an interior of the fuel tank, and an electrically operated vent valve having an inlet communicated with the interior of the fuel tank and an outlet for venting fuel vapor from the fuel tank. The vent valve is movable in response to an electric signal between an open position allowing fuel vapor through the outlet and a closed position to restrict fluid flow through the outlet. A controller is operably communicated with the vent valve to control application of an electric signal to the vent valve and thereby control at least in part the movement of the vent valve between its open and closed positions. In one embodiment the controller is responsive to a fill level in the fuel tank to control the position of the vent valve and thereby the fill level attained within the fuel tank.

Abstract: An in-tank fuel module for a fuel tank having a conductive lead for connection to an electrical ground plane and at least a first electrically conductive component, and a conductive polymeric strand electrically connecting the component to the lead. A jet aspiration pump is made of conductive polymeric material. A conductive component is connected to the ground plane through the fuel level sensing assembly circuit.

Abstract: A no-return loop fuel injection system supplies fuel from a fuel pump to an injector fuel rail, through a fuel line. A biased closed pressure control valve communicates with the fuel line and has a valve head preferably of a diaphragm type carrying a fuel side having first and second areas which are segregated and defined by a valve seat when the pressure control valve is closed. An opposite second side of the pressure control valve is exposed to a reference pressure and a closure biasing force. The pressure control valve opens when a hydraulic opening force induced by a fuel pressure exerted upon the first area, plus a fuel pressure exerted upon the second area, is greater than the net reference pressure and closure biasing forces. Preferably, the first area is smaller than the second area, thus manipulating the effects of the fuel pressures exerted upon the first and second areas with respect to opening the valve.
