Abstract

Clapet antiretour 9 placé dans une canalisation d'aspiration entre un réservoir à dépression, notamment d'un dispositif de freinage assisté pour des véhicules, et une pompe à vide, le clapet étant constitué par un siège 8, un corps de clapet 10 et un ressort de pression 11, caractérisé en ce que le corps de clapet est réalisé, par rapport à la section transversale de la portion de canalisation dans laquelle il est disposé, de telle sorte que, sous l'effet d'un débit d'air déterminé, il agit comme flotteur et est déplacé contre la force antagoniste du ressort de pression contre une ouverture 13 et qu'il obture celle-ci qui, en tant qu'une d'au moins deux ouvertures 13, 14, étrangle la section d'écoulement de la portion de canalisation. Grâce à cette disposition, on limite la quantité d'air introduite dans un carter et on empêche ainsi un fonctionnement défectueux du moteur. (CF DESSIN DANS BOPI)
