用燃料噴射ポンプ。 A control sleeve is slidably fitted onto the plunger, a control rod is engaged with the control sleeve, and the control rod is driven by an actuator to change the relative position in the axial direction between the plunger and the control sleeve for pre-stroke. In a fuel injection pump that is designed to adjust the flow rate, correction is made in the injection pump body or at a suitable location from the connector to the control position in response to variations in the control position due to errors in the motion transmission system between the actuator and the control sleeve, errors in the actuator mounting position, etc. 1. A fuel injection pump for an internal combustion engine, characterized in that a target actuator operating position is corrected by the resistor.
