Abstract

PURPOSE: To prevent a sharp pressure rise at an injection nozzle to reduce a combustion noise, by supplying pressurized fuel through jet passage provided in a fuel injection pump, when the revolution speed of an engine is low.
CONSTITUTION: A plunger 7, which is rotated and reciprocated by a cam 8, is installed in a pump housing 3 to pressurize fuel in a pump pressure chamber 10. A distribution recess 20 is provided on the peripheral surface of the plunger 7 so that one end of the recess 20 is connected to the pressure chamber 10 through the first pressure supply passage 14 and the other end is connected to an injection nozzle 22 through the second pressure supply passage 21. A control valve 15 provided with a communication passage 16 of large diameter and a jet passage 17 of small diameter is installed at the first pressure supply passage 14. When the revolution speed of an engine is low, fuel is supplied under pressure through the jet passage 17 of the valve 15.
