Abstract

L'invention concerne un robinet de mélangeage d'eau froide et d'eau chaude, qui comprend un dispositif sensible à la température, un dispositif sensible à la pression et un ensemble de soupapes destiné à convertir la pression. Pendant l'alimentation en eau chaude, si la température d'eau chaude n'atteint pas une valeur prédéterminée, on commute l'ensemble de soupapes de façon que l'eau chaude circule dans un tuyau d'eau froide ou dans un tuyau de retour. De plus, lors d'une augmentation graduelle de la température, on actionne l'ensemble de soupapes pour le faire revenir à l'état d'alimentation normal. En outre, un utilisateur peut utiliser l'eau dont la température est égale ou supérieure à celle de la valeur prédéterminée.
