Abstract

Ce dispositif comprend un corps (3) délimitant un canal d'écoulement de carburant (4), un dispositif antiretour (8) comportant un siège (9) monté de manière étanche dans le canal d'écoulement (4) et un obturateur (19) mobile entre des positions de fermeture et d'ouverture du dispositif antiretour, et un filtre (25) monté sur le dispositif antiretour (8). Des rainures de passage de carburant (7) sont ménagées sur la surface intérieure du corps (3). Un joint à lèvre (11) est monté sur le siège (9). Le dispositif antiretour (8) est monté mobile en translation axiale entre une première position dans laquelle la lèvre (13) est située entre une première extrémité du corps et les rainures de passage (7) et coopère avec la surface intérieure du corps (3), et une seconde position dans laquelle la lèvre (13) découvre une portion des rainures de passage (7), le dispositif antiretour (8) étant soumis à l'action d'un ressort de rappel (29) qui maintient le dispositif antiretour dans sa première position si la pression en amont du filtre (25) ne dépasse pas une valeur prédéterminée.
