It can thereby be achieved that the ignition position can be set with the greatest possible safety and accuracy, and the setting of this ignition position can be carried out in a simple manner.

Abstract

L'invention concerne un robinet à gaz servant à régler un débit volumétrique de gaz vers un brûleur à gaz (4). Le robinet à gaz selon l'invention comprend un arbre de commande (10) qui règle le débit volumétrique de gaz par un actionnement rotatif et qui est poussé en appui contre une coulisse de guidage (12) du robinet à gaz pour permettre le mouvement rotatif. Cette coulisse de guidage (12) comprend une première butée (13) qui limite un mouvement rotatif de l'arbre de commande (10) à une première position de fonctionnement dans laquelle un débit volumétrique minimal de gaz permet un allumage sûr. Pour étendre la fonctionnalité du robinet à gaz, la coulisse de guidage (12) comprend une deuxième butée (15) qui limite le mouvement rotatif de l'arbre de commande (10) à une deuxième position de fonctionnement.
