る燃料噴射ポンプ。In a fuel injection pump that operates a delivery valve with the pressure of fuel pressurized in a plunger chamber and forcefully delivers fuel in the plunger chamber to a discharge valve chamber through a valve hole, the valve hole has an opening that communicates with the plunger chamber side. The delivery valve has a small diameter hole, and the delivery valve includes a seat that approaches and separates from the discharge valve chamber side opening of the valve hole, and a sliding guide that slides within the valve hole and forms a dashpot between the small diameter hole and the small diameter hole. a small-diameter protrusion that protrudes from the sliding guide part and enters the small-diameter hole freely, and one end of which opens into the small-diameter protrusion and the other end of which extends around the circumference between the seat part and the sliding guide part. A fuel injection pump characterized by comprising a fuel passage opening in a surface.
