Abstract

L'invention a pour but, soit de donner une information, par enregistrement ou comptage, sur le franchissement d'une température donnée, soit de déclencher une action de régulation. Par exemple, pour réguler la température de l'eau débitée par un mélangeur de fluides (chaud et froid), un aimant permanent 15, attire une pièce en matériau magnétique doux à point de Curie égal à la température fixée. Un ressort 19 rappelle la pièce par intermédiaire d'un piston 17 dont la tige supporte une fourchette 20, 21 commandant des vannes décalées 23/24 et 25/26 sur les arrivées d'eau respectivement chaude et froide. L'invention s'applique aux indicateurs de décongélation et à tout système automatique dont le cycle est fonction de la température.
