Abstract
PURPOSE: To eject fuel from the nozzle with high pressure and improve the output by connecting, between fuel ejection pump and nozzle, a pressure accumulator in which the pressure of fuel is accumulated after the fuel has passed through a pre- pressuring plunger.
CONSTITUTION: By fuel supply plunger 2 provided inside fuel ejection pump 1, high-pressure fuel is supplied to the nozzle (not shown) from ejection pipe 11 via fuel gallery 12. Behind plunger 2 are placed vane 21 and intake return valve 7, and thereby fuel is adjusted. Three-directional holder 9 placed in front of ejection pipe 11 is connected to pressure accumulator 6 via check valve 4b. Fuel which has been compressed by pre-pressuring plunger 3 is drawn into pressure accumulator 6 from conduit 5 having check valve 4a, and the fuel ejected from ejection pipe 11 is discharged in the condition of high pressure.
