SOLENOID VALVE

摘要

A solenoid valve having no air leakage, no problem like hunting, and is simple in structure. A single movable valve can open and close two valves of a supply valve and a discharge valve that are arranged perpendicularly to each other. Even when the movable valve receives negative pressure from the discharge valve, the movable valve does not open because the direction in which the movable valve is urged by the negative pressure and the direction of the movement of the movable valve are perpendicular to each other. Therefore, air leakage is prevented from occurring, hunting does not occur, and pressure control of load can be conducted stably. An electromagnet with strong magnetic force is not necessary to be installed and a check valve is not required, so that the structure can be simplified.
