Abstract
(EN)
L'invention concerne un dispositif de recirculation de gaz d'échappement d'un moteur thermique, comprenant une vanne (7) comportant un corps (8) ayant une chambre (9) dans laquelle au moins un conduit (5, 6) débouche par un siège (11, 12) en regard duquel s'étend un élément de régu¬ lation (15) mobile entre une position d'obturation et une position de dégagement du conduit. L'élément de régulation est monté mobile entre une position appliquée contre le siège et une position décollée du siège et la vanne com¬ prend des moyens de déplacement (22, 24 ; 22, 27) de l'élé¬ ment de régulation entre sa position appliquée et sa posi¬ tion décollée, les moyens de déplacement comportant un or¬ gane de rappel (24 ; 27) de l'élément de régulation en po¬ sition décollée lorsque le moteur thermique est arrêté.
