Abstract

Le filtre (1) de liquide de lubrification de moteur à combustion comprend un boîtier (2) ayant dans une base (B) une entrée (2a) pour du liquide brut et une sortie (2b) pour du liquide purifié accessible via un puits. Un insert filtrant (4), logé dans ce boîtier (2), présente un tube solidaire d'au moins un élément structurel de l'insert et entouré par un média filtrant annulaire (5). Une tige de purge, pouvant s'engager axialement dans le puits d'évacuation de liquide, comporte : - un bouchon formant une première zone d'étanchéité tige-puits (C1), typiquement annulaire, pour obturer un canal de purge ; - un tronçon dudit tube (7), délimitant un conduit communiquant avec la sortie (2b), dont la face externe présente des gorges circonférentielles axialement espacées entre elles par des bourrelets annulaires qui forment une deuxième zone d'étanchéité tige-puits (C2) adjacente à une zone (Z1) de liquide brut.The combustion engine lubricating liquid filter (1) comprises a casing (2) having in a base (B) an inlet (2a) for raw liquid and an outlet (2b) for purified liquid accessible via a well. A filter insert (4), housed in this casing (2), has a tube integral with at least one structural element of the insert and surrounded by an annular filter medium (5). A purge rod, which can be engaged axially in the liquid evacuation well, comprises: - a plug forming a first rod-well sealing zone (C1), typically annular, to close off a purge channel; - a section of said tube (7), delimiting a duct communicating with the outlet (2b), the outer face of which has circumferential grooves axially spaced from one another by annular beads which form a second rod-well sealing zone (C2) adjacent to a zone (Z1) of raw liquid.
