    Abstract: A fuel supply system for an internal combustion engine in which an electrical fuel pump pumps fuel from a fuel tank to a fuel distributor and a pressure switch is connected to respond to the pressure of the fuel. The pressure switch is electrically connected to connect and disconnect electrical power supply to the fuel pump as a function of lower and upper threshold values of pressure of the pumped fuel. The pressure switch contain a storage chamber which stores fuel when the fuel pump is operative and when the pump is disconnected, the storage chamber supplies the stored fuel to the full distributor with no back flow to the fuel tank. A pressure reducing regulator is located between the pressure switch and the fuel distributor to reduce the pressure of the fuel supplied to the distributor to a value lower than the pressure of the fuel at the pressure switch.

    Abstract: An impeller for use in a regenerative pump for pumping automotive fuel to an engine includes a plurality of vanes radially extending from a core. Each vane has a leading surface, a trailing surface, and a sidewall between the leading surface and the trailing surface. A plurality of partitions is interposed between the vanes such that the vanes and partitions define a plurality of vane grooves. Fuel is then pumped by the vanes through the vane grooves such that the fuel flows along a generally spiral path thereby defining a primary vortex. A relief is formed at least partially along the length of each vane at the intersection between the trailing surface and the sidewall. This relief causes the fuel flowing along the generally spiral path, also known as the primary vortex, to also rotate about an instantaneous axis thereby defining a secondary vortex. The secondary vortex has the benefit of reducing turbulence with the attendant benefit of reducing cavitation or vapor generation within the fuel pump.

    Abstract translation: 用于将汽车燃料泵送到发动机的再生泵中使用的叶轮包括从芯径向延伸的多个叶片。 每个叶片具有前表面，后表面和在前表面和后表面之间的侧壁。 多个分隔件插在叶片之间，使得叶片和隔板限定多个叶片槽。 然后，燃料通过叶片泵送通过叶片槽，使得燃料沿着大致螺旋状的路径流动从而限定初级涡流。 至少部分地沿着每个叶片的长度在后表面和侧壁之间的交叉处形成浮雕。 这种浮雕使得燃料沿着一般螺旋路径流动，也称为初级涡流，也围绕瞬时轴线旋转，从而限定二级涡流。 二次涡流有利于减少湍流，同时具有减少燃料泵内气蚀或蒸汽产生的优点。

    Abstract: An electric-motor fuel pump that includes a housing with a fuel inlet and a fuel outlet, and an electric motor with a rotor responsive to application of electrical power for rotating within the housing. A pump mechanism includes an impeller coupled to the rotor for corotation with the rotor and having a periphery with a circumferential array of impeller vanes. A pair of plates oppose the sides of the impeller and a split ring surrounds the periphery of the impeller to form an arcuate pumping channel around the periphery of the impeller. Inlet and outlet ports at opposed ends of the pumping channel are operatively coupled to the inlet and outlet in the pump housing. Channels extend radially inwardly from the pockets in each side face of the impeller, and are interconnected by through-passages that extend through the impeller. A vapor vent is disposed in one of the side plates for sequential registry with the impeller through-openings for venting vapor from the pumping channel.

    Abstract: A motor-vehicle engine system has an internal-combustion four-cycle engine having a fuel-supply manifold and operable at variable speed with a fuel requirement dependent on speed, a substantially closed but vented fuel tank holding a supply of gasoline, a fuel pump having an input connected to the tank and an output, and a fuel-feed line connected between the fuel-pump output and the fuel-supply manifold. A controller connected to the engine and to the pump operates the fuel pump at a throughput rate equal to between 5% and 40%, preferably 10% to 30%, more than the instantaneous fuel requirements of the engine. A return line connected to the fuel tank is provided with an overpressure valve that opens and returns to the tank fuel in the manifold that is in excess of the engine's instantaneous requirements and thereby maintains a predetermined constant pressure in the fuel-supply manifold.

    Abstract: A fuel delivery system for an internal combustion engine that includes a fuel supply, an electric-motor pump for feeding fuel under pressure from the supply to an engine, and electronic control circuitry for applying electrical power to the pump. The control circuitry includes a pressure sensitive switch coupled to the pump and responsive to pump outlet pressure for switching between conductive and non-conductive switch conditions at a preselected pump outlet pressure. A pulse width modulation amplifier is coupled to the switch for applying pulsed d.c. energy to the pump at a first average voltage level when the pressure switch is in one condition, and at a second lesser but non-zero level when the pressure switch is in the other condition. In this way, electrical power is applied to the pump motor at a reduced level when pump outlet pressure exceeds the threshold level of the pressure switch.

    Abstract: A motor vehicle fuel pump including a tubular steel housing and a roller vane positive displacement pump and an electric motor in the tubular steel housing. The roller vane pump includes a pair of flat side plates, a rotor between the side plates, and a T-shaped sleeve bearing in a plain bore in one of the side plates. A lip at one end of a tubular body of the sleeve bearing has a side defining an annular seat in a plane perpendicular to the tubular body. The tubular body has a shaft bore therethrough and a stepped outer wall including a large diameter part adjacent the annular seat and a small diameter part adjacent the large diameter part. The large diameter part is force fitted in the plain bore until the annular seat engages flush against a flat, outside surface of the side plate. The annular seat positions the longitudinal centerline of the tubular body perpendicular to the outer side plate for optimum alignment with the armature shaft when an end of the latter is disposed in the shaft bore. The pump rotor is rotatably supported on the small diameter part of the sleeve bearing which protrudes beyond the outer side plate.
