A solenoid valve assembly for a combustible gas supply device to an endothermic engine is disclosed. The solenoid valve assembly includes a solenoid valve with at least one combustible gas outlet and an armature controlled by an electromagnet, the armature having an armature plate and a shutter. The armature plate rotates about a contact line. The armature plate is engaged by a bar pushed against the plate by a spring so as to normally keep the shutter in closed position. The solenoid valve assembly includes a hollow body that may be connected to an intermediate plate that may be connected to a closing plate module. The closing plate module carries a variable number of outlet conduits. The intermediate plate is provided with a series of grooves adapted to accommodate a series of different gaskets, each gasket corresponding to a closing plate module.

The invention claimed is: 1. 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. 2. The solenoid valve assembly of claim 1, wherein the contact line is located between a first surface of the armature plate and a second surface of the armature plate, the second surface of the armature plate being slanted with respect to the first surface of the armature plate. 3. The solenoid valve assembly of claim 1, wherein the spring is a helical compression spring. 4. The solenoid valve assembly of claim 1, wherein the bar is formed from an elastomer. 5. The solenoid valve assembly of claim 1, wherein the fixed element comprises a gap plate that completes the magnetic circuit of the electromagnet. 6. The solenoid valve assembly of claim 5, wherein the gap plate further comprises a plurality of tabs, each of the tabs engaging a core of an electromagnet, the tabs further comprising holes to facilitate the draining of oily components of the combustible gas. 7. The solenoid valve assembly of claim 5, wherein the gap plate has a thickness from 0.015 mm to 0.15 mm. 8. The solenoid valve assembly of claim 1, wherein the solenoid valve assembly further comprises an outlet union in communication with the outlet, the flow of combustible gas from the outlet into the outlet union being controlled by the solenoid valve. 9. The solenoid valve assembly of claim 8, wherein the engine comprises a plurality of cylinders, each cylinder of the engine being supplied by an outlet conduit in communication with the outlet union. 10. The solenoid valve assembly of claim 9, wherein the armature of the solenoid valve is controlled to modulate the flow of the combustible gas into the engine cylinders. 11. The solenoid valve assembly of claim 10, wherein the armature of the solenoid valve is controlled to modulate the flow of the combustible gas to the engine cylinders according to a predetermined diagram. 12. The solenoid valve assembly of claim 1, wherein solenoid valve assembly comprises a hollow body, the hollow body being connected to a closing plate, the closing plate comprising an outlet union. 13. The solenoid valve assembly of claim 12, wherein the solenoid valve assembly further comprises an intermediate plate between the hollow body and the closing plate, the intermediate plate comprising the outlet of the solenoid valve. 14. The solenoid valve assembly of claim 12, wherein the closing plate is a closing plate module having an outlet channel. 15. The solenoid valve assembly of claim 14, wherein the intermediate plate comprises a plurality of grooves, each of the grooves being configured to receive one of a plurality of gaskets, each gasket corresponding to a closing plate module. 16. The solenoid valve assembly of claim 14, wherein the closing plate module comprises a plurality of coplanar and parallel outlet channels. 17. The solenoid valve assembly of claim 14, wherein the closing plate module comprises a plurality of coplanar and divergent outlet channels. 18. The solenoid valve assembly of claim 1, wherein the electromagnet is controlled by a printed circuit located inside the solenoid valve assembly, the printed circuit having a wiring with a single connection located outside the solenoid valve assembly.
