Claims

[Scope of utility model registration request]

A barrel stored in the housing, a plunger inserted into the barrel so as to be slidable in the axial direction,
a spring-loaded discharge valve mounted within said barrel;
A pump chamber bounded within the barrel by the discharge valve and one end surface of the plunger; a fuel chamber within the barrel formed surrounding the plunger; a pump chamber that is slidably fitted outside the plunger within the fuel chamber; an oil passage in the plunger whose one end opens into the pump chamber; an outer circumferential surface of the plunger and one of the control sleeves for communicating or blocking communication between the pump chamber and the fuel chamber via the oil passage; a control groove provided at an angle with respect to the axis of the plunger; a control hole provided on the other of the outer peripheral surface of the plunger and the control sleeve and cooperating with the control groove; and an injection amount for rotating the control sleeve around the axis of the plunger. A control member and an injection timing control member for moving the sleeve in the plunger axial direction, wherein the injection amount control member and the injection timing control member are disposed on one side of the control sleeve in the radial direction, and A fuel injection device characterized in that an injection timing control member and an injection amount control member are operatively connected so as not to interfere with their respective functions.
