Abstract
(EN)
A filter cartridge includes an open-ended housing and filter element supported in the housing and defining an annular region between a periphery of the filter element and a side housing wall. A water collection region is between an end of the filter element and a lower-housing wall. The filter element includes pleated media surrounding an axially-extending central area, and pleats of different heights round the central area. An end plate is bonded to the filter element to prevent fluid flow through the pleats' upper ends. One passage is through a plate opening into the central area. Another passage is between the end plate and peripheral region. The filter element has freely-supported lower ends. A seal between the lower periphery of the filter element and the housing prevents fluid bypass of the filter element. Fluid passes through the pleats, and water coalesces on the media and drains into the collection region.

Une cartouche filtrante comprend un boîtier à extrémité ouverte et un élément filtrant supporté dans le boîtier et définissant une région annulaire entre une périphérie de l'élément filtrant et une paroi de boîtier latérale. Une région de collecte d'eau est située entre une extrémité de l'élément filtrant et une paroi de boîtier inférieure. L'élément filtrant comprend des milieux plissés entourant une zone centrale s'étendant axialement, et des plis de différentes hauteurs autour de la zone centrale. Une plaque d'extrémité est liée à l'élément filtrant pour empêcher un écoulement de fluide à travers les extrémités supérieures des plis. Un passage traverse une ouverture de plaque dans la zone centrale. Un autre passage est situé entre la plaque d'extrémité et la région périphérique. L'élément filtrant présente des extrémités inférieures supportées librement. Un joint d'étanchéité entre la périphérie inférieure de l'élément filtrant et le boîtier empêche une dérivation de fluide de l'élément filtrant. Le fluide passe à travers les plis, et l'eau coalescente sur le milieu et s'écoule dans la région de collecte.
