ノズルホルダ。 a spring that urges a needle valve inserted in a nozzle so as to be freely advanced and retractable; and a piston whose pressure receiving area is switched by movement from a seating position and which compresses the spring in accordance with the amount of displacement from the seating position. In a nozzle holder, the oil passage leading to the nozzle side intersects with the axis of the nozzle holder body. a piston operating oil passage is formed in this oil passage, and a blind hole is bored in the piston with one end opening at the top surface of the piston;
A nozzle holder for a diesel engine, characterized in that a part of the blind hole is communicated with the oil passage for operating the piston.
