たことを特徴とするノズルホルダ。 A leak valve chamber is formed in the oil feed passage that feeds high-pressure fuel from the injection pump to the oil reservoir on the outer periphery of the needle valve and the displaced body part, and this leak valve chamber is directly connected to the oil feed passage through a communication hole. Alternatively, the connection is made indirectly through an oil reservoir, a plug is installed in the leak valve chamber, and a check valve with a set pressure higher than the nozzle opening pressure is provided between the plug and the leak valve chamber, and the plug is A nozzle holder characterized in that an orifice for controlling the amount of leakage is provided in a portion corresponding to the outlet side of the check valve.
