Title (EN) FILTER THERMAL BYPASS VALVE
(FR) SOUPAPE BYPASS THERMIQUE DE FILTRE
Abstract: front page image
(EN)A filter thermal bypass valve (25) has an opening defining a seat (48) a thermal actuator (58) including a plunger (60) capable of being forced toward the seat in response to increases in temperature, a spring retainer (50) capable of movement toward and away from the seat, a rod member (74) affixed to the spring retainer (68) and having an enlarged head portion (76) with a valve plate (78) slidable thereon, a first compression spring (82) forces the retainer in contact with the plunger and a second compression spring (84) urges the valve plate against the seat. The thermal actuator (58) contains a special material which expands greatly when heated, the expansion causing the plunger or piston (60) to extend from the actuator body forcing the spring retainer toward the seat (60) until the valve plate or disk (78) contacts the valve seat (48).
(FR)Une soupape bypass thermique de filtre (25) possede une ouverture definissant un siege (48), un organe d"actionnement thermique (58) comprenant un piston (60) pouvant etre force vers le siege en reponse a des augmentations de temperature, un organe de retenue a ressort (50) capable d"effectuer un mouvement vers et en retrait du siege, une tige (74) fixee a l"element de retenue a ressort (68) et ayant une partie de tete agrandie (76) avec une plaque de soupape (78) coulissant dessus, un premier ressort de compression (42) forcant l"element de retenue en contact avec le piston et un second ressort de compression (84) poussant la plaque de soupape contre le siege. L"organe d"actionnement thermique (58) contient un materiau special qui se dilate considerablement lorsqu"il est chauffe, la dilatation obligeant le piston (60) a se deplacer depuis le corps de l"element d"actionnement forcant l"element de retenue du ressort vers le siege (60) jusqu"a ce que la plaque de soupape ou disque (78) soit en contact avec le siege de soupape (48).
