Abstract

Un palpeur de température rempli d'une substance dilatable, possède une cloison mobile 11 qui agit sur la partie médiane 4 d'une porte-contact basculant 1 fixé rigidement d'un côté, partie médiane qui peut passer brusquement d'un côté à l'autre de ce porte-contact. L'extrémité libre 7 du porte-contact basculant 1 porte un contact mobile 8 et peut se déplacer entre un contact fixe 9 et une butée 10. La cloison mobile 11, en réponse à une élévation de température, agit à l'encontre du mouvement d'ouverture du contact mobile 8, tandis qu'une touche de réarmement 14, lorsqu'elle agit sur la partie médiane 4, se déplace dans le même sens que le contact mobile 8. Lorsque la cloison mobile 11 n'agit pas sur la partie médiane 4, le contact mobile 8 ne touche pas le contact fixe 9. Application aux générateurs de chaleur.
