Abstract

L'invention concerne un four à gaz pour autocuiseur utilisant une soupape de régulation présentant une partie de régulation du gaz, une partie de régulation de la vapeur et une partie de réglage électrique. On dispose un diaphragme entre le couvercle et le corps de soupape et on laisse un vide entre le couvercle de soupape et le diaphragme. Le diaphragme s'appuie sur l'extrémité supérieure de la tige de soupape et une ouverture est pratiquée dans le couvercle de soupape reliant l'extérieur du corps de soupape et le vide. Sur un côté de la tige de soupape est disposée une tige, l'extrémité de laquelle repose sur la tige de soupape, tandis que l'extrémité inférieure de laquelle repose sur la languette du microcommutateur. Un gicleur, un sélecteur d'ondes et un panneau de câblage conducteur sont disposés sur le corps de soupape.
