<P>PROBLEM TO BE SOLVED: To improve durability by suppressing wear of a movable core when a solenoid is transversely installed. <P>SOLUTION: A fuel-cell ejector includes a nozzle 46 and a diffuser 48 each arranged in an ejector body, and a solenoid 74 including a movable core 80 provided so as to be displaceable toward the side of a fixed core integrally with a needle 50 by excitation action of a coil 76. A recessed part 89 formed recessedly in a direction separating from the fixed core 78 is provided at the end part along an axial direction of the movable core 80 facing the fixed core 78. A protruding part 91 formed of a shape corresponding to the recessed part 89 is provided at the end part along an axial direction of the fixed core 78 facing the recessed part 89 of the movable core 80. <P>COPYRIGHT: (C)2010,JPO&INPIT |
