Abstract

PURPOSE: To prevent noise and vibration created at low speed running by providing a fuel injection pump with a mechanism which reciprocates a roller holder so as to change strokes of a plunger which moves with the holder.
CONSTITUTION: A plunger 5 which rubs inside a cylinder 8 is reciprocated and turned by a roller holder 15 and a drive shaft 1 to supply a compressed fuel through a distribution passage 11 to an injection valve. Tapered rings 19, 19' are formed on a cam plate 3 fixed to the end of the plunger 5. The cam plate 3 is joined with a coupling 2 by means of each ring and contacts the holder 15. A slide pin 20 is projected on the ring 19 and moved by an injection controlling piston 21 which is actuated with a control valve 24 in response to a signal of a control unit 25, thereby especially changing an amount of fuel injected at low speed running.
