ABSTRACT:
A fuel injection pump according to the present invention is provided with a spill passage and an escape passage which are connected to a pump chamber. Disposed in the middle of the spill passage is a solenoid valve, which is adapted to open the spill passage to spill fuel in the pump chamber to the low-pressure side at predetermined times while the fuel in the pump chamber is pressurized by a pump plunger, thereby adjusting the delivery of compressed fuel from the fuel injection pump. The escape passage is formed in the pump plunger so as to be coaxial therewith. One end of the escape passage communicates with the pump chamber, while the other end opens to the outer peripheral surface of the pump plunger. An escape ring is fitted on the outer peripheral surface of the pump plunger, whereby the opening of the escape passage is opened when the pump plunger reaches a predetermined compression stroke.
