Claims

[Scope of utility model registration request]

A fuel injection pump for a diesel engine, comprising a roller, and a plunger driving cam disk having a face cam whose end surface is in sliding contact with the roller, and which is driven by an engine to rotate and reciprocate under the action of the face cam. , supporting the roller so as to be movable in the radial direction of the cam disk, forming the face cam so that its gradient changes over the radial direction of the cam disk, and being rotationally driven by an engine to move the roller to the face using centrifugal force. 1. A fuel injection pump for a diesel engine, comprising: a roller moving device for moving the cam toward a steeper slope; and an urging device for urging the roller toward a gentler slope of the face cam.
