Patent ID: 7857283

Claim:
A solenoid valve assembly for a combustible gas supply device to an endothermic engine, the solenoid valve assembly comprising: a solenoid valve comprising an electromagnet, an outlet for the combustible gas, and an armature controlled by the electromagnet, the armature comprising an armature plate and a shutter connected to the armature plate, the shutter movable between an open position to allow the flow of combustible gas into the outlet and a closed position to prevent the flow of combustible gas into the outlet, the shutter being located in the open position when the armature is activated by the electromagnet, the armature plate rotatable about a contact line against the surface of a fixed element; and an elastic element acting on the armature plate to keep the shutter in the closed position when the armature is not activated by the electromagnet, the elastic element comprising a member pushed against the armature plate by a spring, the elastic element further comprising a compensation plate located between the spring and the member, the member defining a curved portion that engages the armature plate and a flat portion that engages the compensation plate.
