An object of the present invention is to provide a thermostat device which ensures a smooth slide without damaging the slide function by immersion of a cooling liquid, increase flexibility of a circulation channel design by miniaturization, and materializes a hand-operated opening and closing of a valve. In order to solve the problems, the thermostat device 1 in which a heat expansion element (wax 3) to expand and shrink by sensing the heating or cooling of the circulating liquid in the circulation channel, is embedded, a sliding member (piston rod 9) is slid in accordance with volume changes caused by the expansion and shrinkage of the expansion element to open and close the valve body, is structured that a sensor case 2 which embeds the expansion element is placed in the circulation channel of the circulating liquid, and the sliding member is placed outside of the circulation channel of the circulating liquid.
Cette invention concerne un dispositif thermostatique assurant l'ouverture et la fermeture d'un robinet, dans lequel le mouvement coulissant de l'élément de commande du robinet n'est pas perturbé par le contact d'un liquide refroidissant et le circuit du liquide est rendu plus souple par miniaturisation. Le dispositif thermostatique 1 de cette invention, comportant un élément thermosensible (cire 3) qui se dilate ou se contracte selon la température du liquide avec lequel il est en contact et un piston 9 qui se déplace en fonction des variations de volume causées par la dilatation et la contraction de l'élément thermosensible et provoque l'ouverture et la fermeture du robinet, est construit de manière que le composant 2 renfermant l'élément thermosensible est placé dans le circuit du liquide, alors que le piston est placé en dehors de ce circuit.
