Abstract

Die Erfindung betrifft eine Einrichtung zur Entlüftung eines Kurbelgehäuses einer Brennkraftmaschine, bei der die so genannten Blowby-Gase über im Zylinderkopf (7, 8) integrierte Bohrungen und daran angeschlossene Entlüftungsleitungen abführbar sind, wobei die Entlüftungsleitungen an eine Unterdruckquelle, z.B. einem Saugrohr, angeschlossen sind, sowie mit Mitteln (26, 28) zum Vorabscheiden von ÖI aus den Blowby-Gasen.The invention relates to a device for venting a crankcase of an internal combustion engine, in which the so-called blow-by gases in the cylinder head (7, 8) integrated holes and vent lines connected thereto can be discharged, the vent lines to a vacuum source, e.g. a suction pipe, and means (26, 28) for pre-separating oil from the blowby gases.

Es wird vorgeschlagen, dass mindestens ein separates Ölabscheidemodul (26, 28) vorgesehen ist, dessen darin ausgebildete Ölabscheidekammer (30, 31) erste Öffnungen (66, 68) für die Einleitung der Blowby-Gase und zweite Öffnungen (50 bis 56) für die Rückführung des abgeschiedenen Öls in den Zylinderkopf (7, 8) aufweisen.

Figure imgaf001
It is proposed that at least one separate Ölabscheidemodul (26, 28) is provided, the formed therein Ölabscheidekammer (30, 31) first openings (66, 68) for the introduction of the blow-by gases and second openings (50 to 56) for the Return of the separated oil in the cylinder head (7, 8).
