Claims

[Claims for Utility Model Registration] A spring-loaded discharge valve that communicates with a pressurized chamber formed in the housing, one end of which is the pressurized chamber! a plunger whose other end is operatively connected to a cam driven by an engine; an oil passage within the plunger whose one end communicates with the pressurizing chamber; a fuel chamber provided in a housing surrounding the plunger; A control sleeve is slidably fitted on the outside of the plunger in the fuel chamber, and a control sleeve is fitted on the outer circumferential surface of the plunger and one of the control sleeves to connect or block communication between the pressurizing chamber and the fuel chamber via the oil passage. . A control groove provided at an angle with respect to the plunger axis, a control hole provided on the outer peripheral surface of the plunger and the other side of the control sleeve and cooperating with the control groove, and an injection for rotating the control sleeve around the plunger. an injection timing control member for moving the sleeve in the axial direction of the plunger; and a rack member in which the injection amount control member meshes with a gear formed on the outer periphery of the sleeve; 1. A fuel injection pump comprising: a screw shaft that is screwed into the screw shaft; and a fixing device such as a lock nut that adjustably fixes the rack member onto the screw shaft.
