Abstract

Die Erfindung betrifft eine Einrichtung (1) für die Regelung des Drucks im Kurbelgehäuse einer Brennkraftmaschine, mit mindestens einem Druckregelelement (2), wobei die Einrichtung (1) für eine Entölung des Kurbelgehäuseentlüftungsgases mindestens zwei in dessen Strömungsweg angeordneten Ölnebelabscheider (3) umfaßt, wobei in der Einrichtung (1) der Strömungsquerschnitt auf mehrere Einzelkanäle (31) verteilt ist, wobei durch das mindestens eine Druckregelelement (2) der Querschnitt jedes Einzelkanals (31) veränderbar ist, wobei mindestens zwei Einzelkanälen (31) je ein eigener Ölnebelabscheider (3) unmittelbar zugeordnet ist und wobei das Druckregelelement (2) ein druckgesteuerter Aktuator (2') mit mindestens einem mit den Einzelkanälen (31) zu deren Querschnittsveränderung zusammenwirkenden Stellorgan (26) ist.The invention relates to a device (1) for regulating the pressure in the crankcase of an internal combustion engine, comprising at least one pressure control element (2), wherein the means (1) for de-oiling the crankcase ventilation gas comprises at least two arranged in the flow path oil mist separator (3), wherein in the device (1) the flow cross section is distributed over a plurality of individual channels (31), wherein the cross section of each individual channel (31) can be changed by the at least one pressure control element (2), at least two individual channels (31) each having its own oil mist separator (3) is directly associated with and wherein the pressure control element (2) is a pressure-controlled actuator (2 ') with at least one with the individual channels (31) cooperating with their cross-sectional change actuator (26).

Die neue Einrichtung ist dadurch gekennzeichnet,
- daß jeder Ölnebelabscheider (3) oder ein Teil der Ölnebelabscheider (3) mit einem eigenen Sammelbehälter oder -raum (36) zum Sammeln des abgeschiedenen Öls versehen ist und
- daß zumindest ein Teil der Sammelbehälter oder -räume (36) jeweils mit einem selbsttätig schaltenden Rückschlagventil (37) versehen ist.

Figure imgaf001
The new facility is characterized
- That each oil mist separator (3) or a part of the oil mist separator (3) with its own collecting container or space (36) is provided for collecting the separated oil, and
- That at least a portion of the collecting container or spaces (36) is provided in each case with an automatically switching check valve (37).
