Title
(EN) FILTER ARRANGEMENT AND SERVICING THEREOF
(FR) AGENCEMENT DE FILTRE ET PROCEDES
Abstract
(EN)
A primary (48, 348, 648, 908) and secondary (50, 350, 650, 910) filter are combined into a single housing (42), and two elements are combined into a single element (46). The primary and secondary filters are fluidly isolated from each other. The primary filter is configured for radial flow, and the secondary filter is configured for axial flow. The filter arrangement can be a top load arrangement or, in another embodiment, a bottom load arrangement. This combination is useable in any system that has a filter upstream of a pump (44) and a filter downstream of a pump (14). The example described is a fuel system. Methods of servicing include simultaneously removing the housing cover along with both the primary and secondary filters.
(FR)
La présente invention concerne des filtres primaire et secondaire qui sont associés dans un logement unique, et deux éléments sont associés en un élément unique. Les filtres primaire et secondaire sont isolés l'un de l'autre de façon fluide. Le filtre primaire est configuré pour un écoulement radial, et le filtre secondaire est configuré pour un écoulement axial. L'agencement de filtre peut être un agencement à chargement par le haut ou, dans un autre mode de réalisation, un arrangement à chargement par le bas. Cette combinaison est utilisable dans un système quelconque qui comporte un filtre en amont d'une pompe et un filtre en aval d'une pompe. L'exemple décrit est un réseau de carburant. Des procédés d'entretien comprennent la dépose simultanée du couvercle de logement conjointement aux filtres primaire et secondaire.
