Abstract:
1. A solenoid valve device installed in a gas tank in which the solenoid valve device is provided in a gas tank for filling high pressure gas therein, and a movable core is attracted to or distracted from a fixed core by one of energization or non-energization of a coil so that a valve element is attached to or detached from a valve seat for opening/closing operation; the solenoid valve device comprising: a valve body that includes a flow passage formed therein to communicate an inside and an outside of the gas tank, the valve body being inserted to the inside from the outside through a mouth hole of the gas tank and attached to the mouth hole, the valve seat being provided in the flow passage, and the movable valve element attached to or detached from the valve seat being provided in the valve body; a solenoid unit that includes the movable core engaged with the valve element and the fixed core facing the movable core to attract the movable core by the energization of the coil and distract the movable core by the non-energization of the coil, the solenoid unit being arranged inside a storage hole formed at an end part of the valve body inside the gas tank; a cap member being provided to cover the end part of the valve body inside the gas tank, an opening formed in an end face of the cap member communicating with the flow passage, and a flat plate-like filter member being disposed in the opening. the solenoid unit is constituted such that the fixed core stored in the storage hole is retained by a retention ring attached to the storage hole, and the fixed core is axially pressed by a resillent member stored in the storage hole.
