PURPOSE: To attain high-speed operation with a simple structure by mounting the first and second magnetic pole members and a biasing means keeping the relative position of both magnetic pole members in a solenoid actuator latchable by residual magnetism between the pole member and the armature without any permanent magnet. CONSTITUTION: This jet fuel system is provided with an electronic control valve and an actuator 100 driving thereof. The actuator 100 involves a roughly cylindrical magnetic pole member 102 in which an annular recessed part 104 is formed, and a wire coil 116 is disposed in a recessed part 114. An armature 108 urged by a spring 130 in the direction apart from the magnetic pole member 102 is disposed so as to space the bottom surface 120 of the magnetic pole member 102. A housing 140 is disposed on the magnetic pole member 102, and the second magnetic pole member 142 is disposed therein, which is biased downward through a spring 144 mounted on a cylindrical pore 146 formed on the upper part of the second pole member 142. |
