Title (EN) FILTER FOR A FUEL INJECTOR
(FR) FILTRE POUR INJECTEUR DE CARBURANT
Abstract:
(EN) A fuel injector filter (32, 52) is disclosed. The filter (32, 52) may include an inner ring (66) concentrically surrounded by an outer ring (74). The inner ring (66) may radially extend between an inner ring inner perimeter (68) and an inner ring outer perimeter (70), and comprise a first port (72) radially extending between the inner ring inner perimeter (68) and the inner ring outer perimeter (70). The outer ring (74) may radially extend between an outer ring inner perimeter (76) and an outer ring outer perimeter (78), and comprise a first aperture (80) radially extending between the outer ring inner perimeter (76) and the outer ring inner perimeter (78). The first aperture (80) may be circumferentially offset from the first port (72). A filtration channel (82) may radially extend between the inner ring outer perimeter (70) and the outer ring inner perimeter (76) and be configured to impede movement of a particle toward the first port (72).
(FR) L'invention concerne un filtre (32, 52) pour injecteur de carburant. Le filtre (32, 52) peut comprendre une bague intérieure (66) entourée de manière concentrique par une bague extérieure (74). La bague intérieure (66) peut s'étendre radialement entre un périmètre intérieur (68) de bague intérieure et un périmètre extérieur (70) de bague intérieure, et comprend un premier orifice (72) s'étendant radialement entre le périmètre intérieur (68) de bague intérieure et le périmètre extérieur (70) de bague intérieure. La bague extérieure (74) peut s'étendre radialement entre un périmètre intérieur (76) de bague extérieure et un périmètre extérieur (78) de bague extérieure, et comprend une première ouverture (80) s'étendant radialement entre le périmètre intérieur (76) de bague extérieure et le périmètre extérieur (78) de bague extérieure. La première ouverture (80) peut être décalée de manière circonférentielle par rapport au premier orifice (72). Un canal de filtration (82) peut s'étendre radialement entre le périmètre extérieur (70) de bague intérieure et le périmètre intérieur (76) de bague extérieure et être conçu pour empêcher le déplacement d'une particule vers le premier orifice (72).
