Abstract

L'invention concerne un module filtre à huile (10) d'un circuit d'huile moteur d'un moteur à combustion interne, en particulier d'un véhicule automobile. Le module filtre à huile (10) comprend un boîtier de module (12), qui présente au moins une entrée (24) et au moins une sortie (34, 64) pour l'huile moteur. Le boîtier de module (12) présente en outre au moins une section de boîtier filtre à huile, dans laquelle au moins un élément de filtre à huile (16) est disposé de manière à être traversé par l'huile moteur vers le filtrage. Le module filtre à huile (10) comprend un dispositif de commande (38) pour un écoulement d'huile dans le circuit d'huile moteur, qui présente au moins un dispositif à soupape de commande réglable (40) présentant au moins deux soupapes (42, 44, 46) et au moins une branche d'entrée d'huile (22, 16, 28, 30). La branche d'entrée d'huile (32, 16, 28, 30) est raccordée avec des entrées de soupape respectives (52) d'au moins deux soupapes (42, 44, 46). Chacune des au moins deux soupapes (42, 44, 46) présente au moins une sortie de soupape respective (56), les sorties étant raccordées respectivement avec l'une des plusieurs branches de sortie d'huile (58, 60, 62). Les au moins deux soupapes (42, 44, 46) sont reliées, de manière commandée et réglable, avec au moins un servomoteur (68).
