Title
(EN) FILTER FOR FUEL INJECTORS
(FR) FILTRE POUR INJECTEURS DE CARBURANT
Abstract
(EN)
A filter for filtering hydraulic fluid in a hydraulically actuated fuel injector. The filter includes a first disc structure and a second disc structure disposed axially spaced apart from the first disc structure. The second disc structure is also disposed parallel to the first disc structure. The filter further includes an intermediate structure extending from the first disc structure to the second disc structure. The intermediate structure includes a first surface and a second surface disposed opposite and parallel to the first surface. The intermediate structure defines a plurality of passages extending from the first surface to the second surface. Each of the plurality of passages is perpendicular to a longitudinal axis of the filter.

L'invention concerne un filtre permettant de filtrer un fluide hydraulique dans un injecteur de carburant actionné hydrauliquement (102). Le filtre comprend une première structure de disque et une seconde structure de disque disposée et espacée axialement de la première structure de disque. La seconde structure de disque est également disposée parallèlement à la première structure de disque. Le filtre comprend en outre une structure intermédiaire s'étendant de la première structure de disque à la seconde structure de disque. La structure intermédiaire comprend une première surface et une seconde surface disposée à l'opposé et parallèle à la première surface. La structure intermédiaire comprend une pluralité de passages s'étendant de la première surface à la seconde surface. Chaque passage de la pluralité de passages est perpendiculaire à un axe longitudinal du filtre.
