Abstract

L'invention a trait à un embrayage fluide. Elle a pour objet un tel embrayage du type comprenant un élément de sortie limitant une chambre de travail de fluide Le dispositif comprend un élément d'entrée rotatif dans la chambre de travail et coopérant avec l'élément de sortie pour délimiter un espace de cisaillement. L'élément de sortie définit une surface interne annulaire, dont au moins une majeure partie coopère avec l'axe de rotation pour définir un angle d'ouverture d'environ 20 à 70 degrés . L'élément d'entrée définit une surface extérieure annulaire, dont une majeure partie épouse sensiblement la surface interne anguleuse de l'élément de sortie et en est faiblement espacée L'embrayage de l'invention possède une vitesse de crête, ainsi qu'un temps de pompage grandement réduit Application : notamment aux entraînements visqueux de ventilateurs de refroidissement de radiateur.
