摘要： A mounting system for electric pumps used in automotive vehicles, especially those in which the pump is installed in the fuel tank. To reduce pump and pump motor vibrations and noise, which may be objectionable to passengers, the pump is mounted within a jacket enclosure carried in the vehicle fuel tank. A suspension for the pump within the jacket consists of identical mount rings of relatively soft flexible material which has internal and external relatively thin projections to contact the inner walls of the jacket on the outside of the ring and to contact the pump housing on the inside of the ring. Radial continuations of the projections establish the axial location of the pump within the jackets.

摘要： A mounting for an electric fuel pump in a fuel tank of a passenger vehicle which includes an oversize, open-ended enclosure to surround a pump within the fuel tank. The enclosure is mounted on a pipe depending into the fuel tank from a cantilever connection. The pump is floatingly mounted in the enclosure by conical coil springs at each end seated respectively on the pump housing and inner flanges of the enclosure. The enclosure is formed of two telescoping portions clamped together by a plate which also traps the depending pipe to support the assembly within the fuel tank.

摘要： An electric motor fuel pump has an inner gear rotor and an outer gear rotor each with a plurality of radially opposed intermeshing teeth each having a pair of driving surfaces and defining circumferentially disposed expanding and ensmalling pumping chambers through which fuel is drawn and then discharged under pressure. The inner gear rotor is coupled to a motor armature journalled for rotation within a fuel pump housing to drive the inner gear rotor and the associated outer gear rotor. The teeth of each gear rotor have a step formed thereon providing a pair of offset driving surfaces on at least each driving face of each tooth and preferably offset trailing surfaces on each trailing face of each tooth. The stepped tooth profile permits greater eccentricity between inner and outer gear rotors which increases the fuel displacement of the gear rotors. The stepped tooth profile also provides more teeth for a given pitch diameter and increased design freedom which facilitates optimization of the drive angle between mated gear rotors.

摘要： A fuel delivery system for internal combustion engines that includes a fuel pump module adapted to be disposed within a fuel tank, with a pump inlet disposed at a lower portion of the tank for drawing fuel therefrom and a pump outlet for delivering fuel under pressure to the engine. An air/vapor purge valve is operatively coupled to the pump outlet. The purge valve is constructed to be open when air and/or vapor is pumped by the fuel pump to purge such air and/or vapor to the surrounding tank, and to be responsive to presence of liquid fuel under pressure at the pump outlet to close the purge valve and prevent passage of liquid fuel therethrough to the surrounding tank.

摘要： A fuel system for a marine engine has a recirculation cooler which receives a portion of fuel discharged from a fuel pump, cools that fuel, and then returns the cooled fuel to the inlet of the fuel pump to reduce fuel vapor formation and to cool the pump as the cooled fuel flows through the pump. The recirculation cooler is preferably formed of a material of high thermal conductivity and has a water passage adjacent to the fuel passage to reduce the temperature of the fuel that flows through the recirculation cooler. The recirculation cooler is preferably used in high heat applications or with a speed controlled fuel pump, with a pulse width modulated drive, for example. In these applications, during at least some fuel flow conditions, the flow of fuel through the fuel pump may be insufficient to cool the fuel pump motor and may cause increased fuel vapor formation. Desirably, the cooler fuel provided from the recirculation cooler to the inlet of the fuel pump supplements the cooling of the fuel pump motor and reduces fuel vapor formation.

摘要： A fuel pressure regulator is provided between the outlet of the fuel pump and an inlet of a jet pump to control the flow of fuel to the jet pump. Desirably, during low voltage conditions in a vehicle, the flow of fuel to the jet pump may be temporarily restricted or terminated to decrease the amount of fuel diverted from the engine and thereby increase the flow rate of fuel to the engine and improve the performance of the engine. The regulator may also function to bypass fuel delivered from the fuel pump in excess of the engine fuel demand to control the pressure of and limit the maximum pressure of fuel supplied to the engine.

摘要： A fuel pump module constructed to be disposed in a vehicle fuel tank has a primary fuel pump with a fuel inlet disposed adjacent the bottom of the module and a fuel outlet which delivers pressurized fuel to an engine and also a jet pump disposed in a recess of the module and closely adjacent the bottom of the fuel tank to draw fuel into the module from the fuel tank in response to fuel flow through the jet pump. Disposing the jet pump in the recess of the module and closely adjacent to the bottom of the fuel tank enables the jet pump to draw substantially all of the fuel from the fuel tank into the module to ensure that the primary fuel pump can deliver an adequate supply of fuel to the engine even during extremely low fuel level conditions in the fuel tank. Disposing the inlet of the primary fuel pump closely adjacent to the bottom of the module and also the bottom of the fuel tank facilitates initial priming of the primary fuel pump after the fuel tank and module become empty and fuel is subsequently added to the fuel tank. Thus, after a vehicle has run out of gas, and the operator pours a small amount of gas into the gas tank, the primary fuel pump is able to prime, operate the jet pump to draw some of the added fuel into the module and deliver added fuel to the engine so that the engine may be started and the vehicle driven to a gas station.
