An oil filter apparatus comprises a base portion (30) having an aperture (26), a drainage valve (18) positioned for movement between an opened position allowing oil to drain out of the base portion (30) through the aperture (26) and a closed position blocking drainage of oil out of the base portion (30) through an aperture (26), a filter module (14) positioned in the base portion (30) to filter oil, a valve actuator (24) coupled to the filter module, and an anti-rotation rib (72) positioned in the base portion (30) and a rib-receiving notch (74) formed in the filter module (14) to block rotation of the filter module (14) relative to the base portion (30) to guide the valve actuator (24) into communication with the drainage valve (18) to move the drainage valve (18) to the closed position when the filter module is installed in the base portion (30).

L'invention concerne un dispositif filtre à huile qui comprend une partie de base (30) dotée d'une ouverture (26) ; une soupape de purge (18) qui se déplace entre une position ouverte qui permet à l'huile de s'évacuer de la partie de base (30) via l'ouverture (26), et une position fermée qui bloque le drainage de l'huile vers l'extérieur de la partie de base (30) via l'ouverture (26) ; un module filtrant (14) placé dans la partie de base (30) pour filtrer l'huile ; un poussoir (24) couplé au module filtrant ; une nervure antirotation (72) placée dans la partie de base (30) ; et enfin, une encoche de réception de nervure (74) formée dans le module filtrant (14) pour bloquer la rotation du module filtrant (14) par rapport à la partie de base (30), et amener ainsi le poussoir (24) en communication avec la soupape de purge (18) pour déplacer cette dernière dans la position fermée lorsque le module filtrant est monté dans la partie de base (30).
