Abstract

Die Erfindung betrifft Ölnebelabscheider (1) einer Brennkraftmaschine, die als Zentrifugalabscheider mit einem in einem Gehäuse (10) angeordneten Rotor (2) in Form eines Tellerstapels (20) und mit einem den Rotor (2) radial außen umgebenden, sich in Axialrichtung des Rotors (2) erstreckenden Gasleitring (3, 3') ausgeführt sind.The invention relates to Ölnebelabscheider (1) of an internal combustion engine, as centrifugal separator with a housing (10) arranged rotor (2) in the form of a plate stack (20) and with a rotor (2) radially outwardly surrounding, in the axial direction of the rotor (2) extending gas guide ring (3, 3 ') are executed.

Ein erster erfindungsgemäßer Ölnebelabscheider ist dadurch gekennzeichnet, dass der Gasleitring (3) relativ zum Rotor (2) nicht mitdrehend ausgebildet ist.A first inventive Ölnebelabscheider is characterized in that the gas guide ring (3) relative to the rotor (2) is not formed mitdrehend.

Bei einem zweiten erfindungsgemäßen Ölnebelabscheider ist vorgesehen, dass der Gasleitring (3') mit dem Rotor (2) mitdrehend ausgebildet ist und eine durchbrochene oder poröse Fläche bildet.
