<p>PURPOSE:To increase the accuracy by coupling the armature of a solenoid actuator with a valve rod, and providing holding means for restricting the movement of the rod around the rod, thereby driving at a high speed in a simple structure. CONSTITUTION:A stator 4 and an armature 5 having exciting coils 8 are opposed, a current is flowed to the coil 8 to move the armature 5 to the stator 4 side, thereby forming a solenoid actuator 1. The armature 5 of the actuator is coupled with a valve rod 9. Holding means 14 for restricting the movement of the rod 9 is provided around the rod 9. Thus, the coil 8 is energized in the state that the rod 9 is held by the means 14, and when sufficient electromagnetic force is obtained, the means 14 is released. Then, the armature 5 can be responded at a high speed.</p> |
