Claims

[Scope of utility model registration request]

(1) A coil is wound around a valve body which is provided with a fluid inlet and a fluid outlet at one end, and a plunger is provided inside the valve body so as to be able to advance and retreat. The plunger is held in a closed position where it closes the outlet, and when the coil is energized, the plunger opens the outlet against force (in a solenoid valve that moves to the open position, the plunger opens the outlet). A solenoid valve characterized in that a communication passage is provided that communicates a space for movement of the plunger formed at the other end of the main body with the outlet side.

(2) A claim for utility model registration characterized in that the communicating passage is used as a throttling mechanism to reduce the pressure of the fluid sent through the inlet when the plunger is held in the closed position. Solenoid valve as described in scope item (1).
