Patent ID: 8567062

Claim:
A method of assembling an electromagnetic gas valve that comprises a first body, a second body, a unit comprising a valve disc and stem assembly coupled to a moveable insulating structure having a projecting member, an electromagnet assembly comprising a magnet fixed within the second body and a coil wound on a moving part with a cavity adapted to receive the projecting member, the first body having a gas inlet, a gas outlet and a through hole disposed between the gas inlet and the gas outlet, in operation the moving part of the electromagnetic assembly acts upon the valve disc and stem assembly to move the disc in a manner to regulate the passage of gas between the gas inlet and the gas outlet through the through hole, the method of assembling the electromagnetic gas valve comprising: providing the second body having the electromagnetic assembly, disposing the unit on the first body or on the second body, joining together the first body and the second body so that the insulating structure is positioned between the first and second bodies and so that the valve disc resides below the through hole in the first body; and coupling the insulating structure to the electromagnetic assembly by introducing a fluid under pressure into the gas outlet or gas inlet to act upon the unit to cause the projecting member to move in a direction towards the inside of the second body and into the cavity of the moving part of the electromagnet assembly.
