Abstract

a. Régulateur automatique de la dépression dans la chambre de combustion d'un foyer, notamment de chaudière, avec une boîte manométrique exposée à la pression gazeuse dans la chambre de combustion ou dans le tuyau d'echappement des fumées. b. Le circuit de réglage comporte un élément comparateur fonctionnant sans contact, qui compare la valeur effective et la valeur nominale, qui transmet des informations de commande en fonction de la différence entre la valeur effective et la valeur nominale à un dispositif de réglage agissant sur l'organe réglant le tirage, de telle façon que ce dernier est actionné plus rapidement si la différence entre la valeur effective et la valeur nominale est grande et plus lentement lorsque cette différence est petite. c. Le régulateur selon l'invention a un réglage stable et précis, les mouvements transitoires indésirables étant supprimés.at. Automatic vacuum regulator in the combustion chamber of a fireplace, in particular a boiler, with a manometric box exposed to the gas pressure in the combustion chamber or in the smoke exhaust pipe. b. The adjustment circuit has a comparator element operating without contact, which compares the actual value and the nominal value, which transmits control information according to the difference between the actual value and the nominal value to an adjusting device acting on the member regulating the draft, so that the latter is actuated more quickly if the difference between the effective value and the nominal value is large and more slowly when this difference is small. vs. The regulator according to the invention has a stable and precise adjustment, the unwanted transient movements being suppressed.
