Claims

[Scope of utility model registration request]

(1) A plunger that is attracted when the coil is energized, a pallbron that is fixed or locked to the central axis of the plunger, and a first and second valve that is fixed or locked to the valve rod.
two annular protrusions having first and second seat surfaces that protrude annularly from the inner periphery of the gas passage and can come into close contact with the first and second valves; first and second springs that bias the valve toward the first and second seats, respectively, the first valve and the first seat forming a first valve part, A gas solenoid valve, characterized in that the second valve and the second seat constitute a second valve section.

(2) Utility Model Registration Scope of Claim 1 The solenoid valve for gas according to claim 1, characterized in that at least one of the first and second valves is slidably held by the pallbrond. .

(3) Utility model registration Scope of claim 2 In the gas solenoid valve according to claim 2, the sliding stroke of the first valve is α, and the sliding stroke of the second valve is β.
and the distance between the first and second valves is 11 when the first and second valves are respectively locked at the latch end side locking portions of the pallblond, and the first and second seats are If the distance between them is 1°, then 1□>1□, at least α is not zero and satisfies the relationship l□-(α-β)≦'1□, and when 11<1° is at least β zero and 1
It is characterized by satisfying the relationship 1+(β-α)≧1°.

(4) Utility model registration Scope of claim 1 The gas solenoid valve includes a connecting rod that is fixed or locked to the second valve and that locks the first valve, The first valve is not provided with a hole through which the pallbrond or the connecting rod is inserted, but is locked or fixed to the rod, respectively.
