摘要:
An electromagnetic directional control valve for changing over flow paths of fluid comprises a plunger disposed in a case and being capable of moving from a neutral position in one axial direction by a first solenoid and in the other axial direction by a second solenoid to participate in the changeover of the flow paths. First and second stoppers bearing against the plunger are moved together with the plunger respectively in one axial direction and the other axial direction. First and second springs bias the first and second stopper respectively in the direction of abutting against the plunger. The plunger is stopped at the first neutral position held by the first and second springs, at a second position to which the plunger is moved in one axial direction by the first solenoid against the first spring and a third position to which the plunger is moved in the other axial direction by the second solenoid against the second spring.
