Title (EN) DUAL-VALVE THERMOSTAT
(FR) THERMOSTAT À DOUBLE SOUPAPE
Abstract: front page image
(EN)A dual-valve reverse poppet thermostat for use in a vehicle cooling system. The thermostat includes a cup having a temperature sensitive element that actuates a piston causing the piston to move axially upwards. Movement of the piston initiates the gradual opening of a preliminary valve to initiate coolant flow and equalize pressure to open a main valve. The preliminary valve and main valve are biased towards a closed position by biasing spring members.
(FR)L'invention porte sur un thermostat à soupape champignon inverse de double soupape, destiné à être utilisé dans un système de refroidissement de véhicule. Le thermostat comprend une cuvette ayant un élément sensible à la température qui actionne un piston en amenant le piston à se déplacer axialement de bas en haut. Le mouvement du piston déclenche l'ouverture progressive d'une soupape préliminaire pour déclencher un écoulement de fluide de refroidissement et égaliser la pression pour ouvrir une soupape principale. La soupape préliminaire et la soupape principale sont sollicitées vers une position fermée par des éléments de rappel élastique.
