Claims

[Scope of utility model registration request]

(1) A twenty-one dollar connected to a movable iron core driven by an excitation coil, and a twenty-one dollar storage tube in which the twenty-one dollar is built-in;
It consists of a 21 dollar valve that opens and closes a nozzle provided at the tip of the 21 dollar storage tube, and a fuel supply pipe is connected to the 21 dollar storage tube, and the In a three-way solenoid valve in which the return valve port and the twenty-one dollar storage pipe are interlocked, a return spring is interposed between the fixed core and the movable core, and a large diameter recess is formed in the cylindrical hole of the movable core. forming and in the large diameter recess,
A fuel control device for a combustion apparatus, characterized in that a spring receiver attached to the rear end of the twenty-one dollar is loosely fitted therein, and a bias spring is inserted to urge the twenty-one dollar toward a nozzle side.

(2) In the above three-way solenoid valve, the fixed iron core is located at a position closer to the tip than the movable iron core, and the return valve port on the back side of the movable iron core is normally closed and is movable only when the excitation coil is energized. The combustion according to claim (1) of claim 1, characterized in that the iron core is attracted to the fixed iron core side and moves forward, and the twenty-one dollars moves to the nozzle side to close the nozzle.
