Abstract

L'invention porte sur des détendeurs de construction simple à nombre de pièces réduit et dont la périphérie du joint est particulièrement hermétique, et sur des climatiseurs d'automobile les utilisant. La partie structurelle du joint (42) en contact avec le bord périphérique intérieur d'un diaphragme (10) fermant un passage (5) du conduit d'air de climatisation fait partie intégrante des vannes (4, 4A, 4B, 4C, 4D, 4E, 4F, 4G, 4H, 4J, 4K) montées sur le passage (5). Le nombre de pièces est réduit puisque les pièces en contact avec le diaphragme (10) ne doivent pas être fabriquées séparément étant donné que le corps principal (40) du détendeur est formé d'une seule pièce avec le diaphragme (10); par ailleurs, on peut éviter les fuites de réfrigérant dans cette partie.
