Title (EN) AIR/OIL SEPARATING DEVICE
(FR) DISPOSITIF DE SEPARATION AIR/HUILE
Abstract:
(EN) An air/oil separating device (52) for removing oil that has become entrained in blow-by gases passing through a crankcase (26) of an internal combustion engine (10). The air/oil separating device (52) includes a spiral element (60) forming a spiral passageway (72) and a perforated tube (62). As the air/oil stream passes through the spiral passageway (72) and contacts its walls, a certain amount of the entrained oil is removed such that it collects at the bottom of the spiral passageway (72). The treated air stream, now having less entrained oil, passes into the perforated tube (62) and exits at an upper axial end (90), while the collected oil drains back into the crankcase (26) via a lower axial end (92). The air/oil separating device (52) can be incorporated within a cap assembly (42) also having an oil-fill cap (54) and/or a PCV valve (56).
(FR) L'invention concerne un dispositif de séparation air/huile (52) destiné à supprimer l'huile qui a été entraînée dans des gaz de fuite traversant le carter (26) d'un moteur à combustion interne (10). Le dispositif de séparation air/huile (52) comprend un élément spiralé (60) qui forme un passage spiralé (72) et un tube perforé (62). Tandis que le flux air/huile traverse le passage spiralé (72) et touche les parois de ce passage spiralé, une certaine quantité de l'huile entraînée est supprimée, dans la mesure où elle s'accumule au fond du passage spiralé (72). Le flux d'air traité, qui comporte alors moins d'huile entraînée, passe dans le tube perforé (62) et sort au niveau d'une extrémité axiale supérieure (90), tandis que l'huile accumulée retourne dans le carter (26) par l'extrémité axiale inférieure (92). Le dispositif de séparation air/huile (52) peut être intégré dans un ensemble bouchon (42) comprenant également un bouchon de remplissage d'huile (54) et/ou une soupape PCV (56).
