Claims

[Claims for Utility Model Registration] A valve part having a plurality of ports and a valve seat in a flow path that communicates these ports, and an excitation coil wound therein for driving the valve body that opens and closes the valve seat. A solenoid valve comprising a bobbin made of a non-magnetic material, a fixed iron core fitted into one end of the center hole, and an electromagnetic part having a movable iron core that slides inside the center hole. A locking part is provided, and a sound deadening member made of an elastic material having compressibility and resilience is attached to the valve side of the locking part, and the sound deadening member is loosely inserted into the outer peripheral surface of the movable iron core. A sound-muffling electromagnetic valve characterized in that a groove is provided, and the axial distance between the sound-muffling member and the side wall of the valve portion in the groove is slightly shorter than the stroke of the movable iron core.
