Abstract (en)

The motor vehicle refrigerant filter has a hollow body (2) housing a molecular filter (83) sandwiched between two mesh discs (84,85). The filter body is closed at the bottom (82) and has the top closed by a cap (73) with entries for inlet and outlet tubes. The inlet opens (89) onto the top of the filter element, and the outlet draws fluid (80) from the bottom of the filter body.

Abstract (fr)

La présente invention concerne un dispositif de filtration pour circuit de fluide réfrigérant comprenant un corps creux (2) et un tamis moléculaire, le corps creux délimitant un espace (2') et étant muni d'un côté d'un fond et présentant de l'autre côté une ouverture fermée par une pièce d'obturation (6). La pièce d'obturation comporte un orifice (11) d'entrée du fluide et est solidaire avec, ou jouxte, le tamis moléculaire qui est séparé de l'espace délimité par le corps creux par un disque poreux ou une grille (20), dite grille inférieure, de retenue du tamis et de passage du fluide. <IMAGE>
