The invention provides a self-contained automatic temperature-responsive three way line valve. A tubular valve member is axially slidable between first and second limit positions for selectively directing fluid from an inlet port to a first outlet port or a second outlet port. The valve member is disposed between a pair of opposed compression springs, one being a conventional spring biasing the valve member to the first limit position and the other being an SME spring which overcomes the bias of the first-mentioned spring when the fluid exceeds a given temperature.
Vanne automatique à trois voies sensible à la température. Un élément de robinetterie tubulaire glisse dans le sens axial entre les première et deuxième position de fin de course pour acheminer le fluide d'un orifice d'entrée vers un premier ou un deuxième orifice de sortie. L'élément de robinetterie est placé entre deux ressorts de pression opposés, l'un étant un ressort classique qui pousse l'élément de robinetterie à la première position de fin de course et l'autre étant un ressort à effet mémoire qui surpasse le premier ressort si le fluide dépasse une température donnée.
