Abstract

Coupleur à fluide pour l'entraînement d'un ventilateur. Selon l'invention, le coupleur destiné au système de refroidissement du radiateur d'un moteur à combustion interne, est du type dans lequel une soupape 22, 24 sensible à la température commande le degré de couplage de rotation entre le moteur et le ventilateur de refroidissement du radiateur, en commandant la quantité active de liquide de couplage dans un coupleur qui relie le moteur au ventilateur. Le perfectionnement porte sur un bilame 30 combiné au coupleur à fluide, la configuration du bilame étant telle qu'il ne peut être monté sur le carter du coupleur autrement que dans un sens prédéterminé par rapport à lui. L'invention évite l'éventualité de surchauffe du moteur due à un montage incorrect du bilame.
