  • Patent number: 5832900
    Abstract: An arrangement and method for recirculating highly pressurized fuel from a fuel rail back to a high pressure pump inlet in which a fuel outflow is controllably allowed from the fuel rail into a nozzle to form a high pressure stream of fuel directed into a port connected to the inlet of the high pressure pump and a flow of fuel from a low pressure supply pump is merged into the stream by a surrounding annular flow pattern. This uses the energy of high pressure fuel to increase the pressure at the inlet of the high pressure pump and greatly reduces the tendency for the fuel vapor to form.
