    摘要： A fuel level measurement device has a fuel level sensor carried by a fuel level float at the distal end of a pivoting float arm of the device which is preferably part of a fuel pump module located inside of a fuel tank preferably for automotive applications. Preferably a sealed arcuate chamber of the float is defined between an electrically conductive cover and a variable electric resistor which preferably is a generally non-conductive ceramic substrate that carries an electrically resistive ink strip. A track exposed in the arcuate chamber has a concave shape that generally faces upward so that a rolling member changes position due to the forces of gravity within the chamber as the float arm pivots generally up and down with changing fuel levels in the tank. The rolling member is electrically conductive and completes the circuit between the electrically conductive cover and the variable resistive ink strip. The sealed chamber provides the pathway for the rolling member and preferably at least in part the buoyancy for the float.

    摘要： A vent valve for a fuel tank with a vapor outlet moves between a fully open position, a fully closed position, and a partially open position. The vent valve has a housing and a cage received at least in part in the housing. The cage has an annular wall with at least one through opening. The wall of the cage defines at least in part a float cavity sized for at least partial receipt of a float. A valve retainer is carried by the float toward the vapor outlet to inhibit the flow of fuel and vapor through the outlet. The valve retainer is moveable relative to the float to at least partially open the vapor outlet, and the valve retainer is moveable conjointly with the float away from the vapor outlet to open the outlet to the flow of vapor.

    摘要： 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.

    摘要： 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. When the pressure control valve is open, the system operating pressure exposed to both the first and second areas is sufficient to produce the hydraulic force necessary to keep the valve open. Preferably, the pressure control valve is part of a pressure valve assembly of a fuel pump module located inside a fuel tank. The pressure valve assembly preferably has a flow check valve orientated in a parallel flow configuration to the pressure control valve when the fuel pump is of a variable speed type, or, for systems utilizing constant speed pumps the check valve is replaced with a flow bypass orifice.

    摘要： 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.
