Auxiliary electromagnetic valve for its incorporation into a main valve of a gas servo valve, which comprises a body with an auxiliary outlet conduit connected to an outlet conduit of the servo valve, a pivoting arm that comprises a closure member of a valve seat of the auxiliary outlet conduit, a ferromagnetic armature that closes the magnetic circuit opening the valve seat, and a return means, supported by a plate, that returns the pivoting arm in order to keep the seating closed. The body is configured by means of a peripheral surface fitted to a cavity of the main valve, a lower surface supported against the cavity by means of fitting means, an intermediate transverse surface on which the valve seat is fitted, a transverse perimetral rim upon which the plate is fixed, and an auxiliary hole that connects the valve seat to the outlet conduit.

What is claimed is: 1. An auxiliary electromagnetic valve for its incorporation into a main valve of a diaphragm type gas servo valve for the supply to a domestic heating appliance, which comprisesa body that includes an auxiliary gas outlet conduit with a valve seat, said auxiliary outlet conduit being connected to a gas outlet conduit of the servo valve,a pivoting arm housed in the body and which comprises an auxiliary closure member for said valve seat,an electromagnet housed in the body,a ferromagnetic armature inserted in the pivoting arm and which closes the magnetic circuit of the electromagnet when it is switched on, moving said pivoting arm and opening the valve seat,a return means for the return of the pivoting arm to a rest position in which the valve seat is kept closed, anda support plate fixed to the body that supports the return means, wherein the electromagnetic valve is built for its integration into a cavity of the main valve that is connected to a control chamber of said main valve, the body of the auxiliary valve being configured by means of a peripheral surface fitted to said cavity, a substantially flat lower surface supported against the bottom of the cavity by means of fitting means, an intermediate transverse surface on which the valve seat is fitted, a transverse perimetral rim upon which the support plate is fixed, and an auxiliary hole that connects the valve seat to the gas outlet conduit.
