A thermostatic mixing valve includes a body (1), inlets (2) and (3) for intake of hot water and cold water and a discharge outlet (4) for delivery of mixed water. A mixing chamber (7) is within the body (1) and is defined by a perimeter wall member (8) that houses a slide valve (9) which slidably moves in the mixing chamber so as to control the opening and closing of the inlets to the mixing chamber (7). A thermostatic element (18) is mounted to control motion of the slide valve (9). A partition (10) is mounted in the mixing chamber (7) between the inlets. A cross passage (11) allows water from one inlet to pass the partition toward the discharge outlet (4). The mixing chamber has an inclined surface (14) to direct water from the other inlet toward the cross passage to promote mixing of the hot and cold water.

Cette soupape de mélangeur thermostatique comprend un corps (1), des orifices d'entrée (2) et (3), destinés à l'admission d'eau chaude et froide, ainsi qu'un orifice d'évacuation (4) servant à la distribution d'eau mélangée. Une chambre de mélange (7) située dans le corps (1) est définie par une paroi périphérique (8) logeant un robinet à tiroir (9) lequel coulisse dans la chambre de mélange de manière à commander, dans la chambre de mélange (7), l'ouverture et la fermeture des orifices d'entrée. Un élément thermostatique (18) sert à commander le déplacement du robinet à tiroir (9). Une cloison (10) est montée dans la chambre de mélange (7) entre les orifices d'entrée. Un passage de communication (11) permet à l'eau provenant d'un orifice d'entrée d'aller au-delà de la cloison en direction de l'orifice d'évacuation (4). La chambre de mélange possède une surface inclinée (14) servant à diriger l'eau, à partir de l'autre orifice d'entrée, vers le passage de communication, afin de favoriser le mélange de l'eau chaude et de l'eau froide.
