Claims

[Claims for Utility Model Registration] The valve body is formed with a valve chamber in which the first to third passages gather, and within this valve chamber there is a first passage having a through hole communicating with both the second and third passages. A valve seat and a second valve seat having a hole communicating with both the first and second roads are formed oppositely, and when the electromagnetic coil is not energized, switching in the valve chamber is performed by the biasing force of the valve spring. While the valve is in contact with the first valve seat, when the electromagnetic coil is energized, the movable iron core is attracted to the fixed iron core by the electromagnetic coil, and the needle of this movable iron core pushes the switching valve, so that the switching valve is A three-way switching solenoid valve that comes into contact with a second valve seat, which eliminates the gap that occurs between the fixed iron core and the movable iron core when the electromagnetic coil is energized, so that the movable iron core is separated from the same room iron core. The movable iron core and the needle are connected by a connecting means that allows movement in the axial direction by a predetermined stroke so that the movable iron core can move in the axial direction of the needle /L/ to the position where they come into contact. Features a three-way switching solenoid valve.
