SOLENOID VALVE

摘要

PURPOSE: A solenoid valve is provided to improve the appearance of a valve and power consumption by preventing the unnecessary increase of electromagnetic power. CONSTITUTION: The upper part of a hollow plunger(1) is corresponding to a core(4). The lower part of the plunger is smaller than the upper part. A pin hole(13) is formed in the plunger by horizontally penetrating the lower part. A hollow assistant plunger(2) is inserted outside the lower part of the plunger. An assistant orifice(12) is formed by extending to the end of the plunger and the inlet of an orifice(10). Electromagnetic power is not increased though the moving amount of fuel is enlarged by the pressure difference in the assistant plunger.
