发明名称 HIGH PRESSURE FUEL PUMP
摘要 PROBLEM TO BE SOLVED: To suppress fuel leakage even when an excessive force is inputted in a needle 46.SOLUTION: To a suction valve 40, a force can be applied in a valve opening direction (right side in the figure) by a needle 46. A movable core 48 is connected to the needle 46. Then, a fixing core 50 is arranged so as to oppose to the movable core 48, and a coil 51 is arranged around the fixing core 50. To the needle 46, a force is applied in the direction for opening the suction valve 40 by a spring 54 for valve opening whose one end is fixed to a spring seat 52. The spring seat 52 has a needle stopper part 52a, and by the needle stopper part 52a, displacement of the needle 46 in the valve closing direction of the suction valve 40 is restricted. The spring seat 52 comes into contact with a stopper 56. One end part of the stopper 56 comes into contact with an impact absorption material 58. The impact absorption material 58 is formed by a member whose rigidity is lower than that of the stopper 56.SELECTED DRAWING: Figure 3
