項記載の燃料噴射ポンプの噴射量補正装置。[Claims for Utility Model Registration] 1. The pump housing of a fuel injection pump that pressurizes and distributes fuel oil to each cylinder by a rotating and reciprocating plunger, which is pumped into the suction space of the pump housing in relation to the engine rotational speed. a storage chamber formed in communication with the suction space via a through hole; a pressure responsive means operated by fuel oil pressure in the suction space and applied to an end face opposite to the through hole, which is disposed within the storage chamber; 1. An injection amount correction device for a fuel injection pump, comprising a response means for controlling a governor mechanism in accordance with a pressure response means. 2. The pressure responsive means is fitted into the storage chamber so as to be slidable in the axial direction, and has a first pressure receiving surface whose end face facing the through hole fits into the through hole, and a second pressure receiving surface which is larger than the first pressure receiving surface. an adjusting pin formed in the shape of a valve body having a cam surface having a predetermined shape in the axial direction at a predetermined position on the circumferential surface, and an ash pressure receiving end surface of the adjusting pin and an opposing surface of the pump housing. The valve is opened when the fuel oil pressure in the suction space applied to the first pressure receiving surface exceeds a first predetermined pressure, and the fuel oil pressure applied to the second pressure receiving surface is applied to the first pressure receiving surface. 2. The injection amount correction device for a fuel injection pump according to claim 1, further comprising a spring that closes the valve when the pressure becomes equal to or less than a second predetermined pressure, which is lower than the predetermined pressure. 3. The response means includes a sensor pin that is slidably disposed on the cam surface facing the cam surface in the radial direction of the adjusting pin, and a sensor pin that is rotatably supported in the suction space and has one end attached to the sensor pin. Claims for registration of a utility model characterized by comprising: a lever that abuts one end of the lever, the other end of which abuts an end of the lever of the governor mechanism, and presses the one end surface of the sensor pin against the cam surface. 1st
An injection amount correction device for a fuel injection pump as described in 1.
