Abstract

PURPOSE: To feed an adequate amount of fuel to an automobile engine in its wide range operational state through the above described device, by connecting the return flow line of a fuel pressure regulator to the richer nozzle passage of a throttle main unit and opening a valve at high loaded operation of the engine at its high speed.
CONSTITUTION: A fuel pressure regulator 12 is provided with a seat part on the upper side of a diaphragm supported by a coil spring, when prescribed pressure fuel passes, the seat part is sealed by a seat, however when high pressure fuel is fed from a pipe 11, the diaphragm is depressed to open the seat part, and a surplus amount of the fuel is released to a pipe 10. While in a throttle main unit 1, negative pressure is generated in a richer nozzle 8 as intake air quantity increases, and a check ball 5 is lifted by overcoming tension of a spring 6, then fuel from a pipe 4 is sucked and supplied from the pipe 10 of the fuel pressure regulator 12 through a fuel passage 14.
