Abstract
The invention relates to a separator (1) for a crankcase ventilation of an internal combustion engine. The separator (1) comprises at least one turbulence chamber (2), which extends along a longitudinal axis (3), wherein said turbulence chamber (2) has a tangential inlet for a ventilation flow (6) at an intake-side end (4) relative to the longitudinal axis (3) thereof. The turbulence chamber (2) additionally has a shared outlet (8) for the ventilation flow (6) and oil (9) entrained with the ventilation flow (6) on the outlet-side end thereof opposite the intake-side end (4) relative to the longitudinal axis (3), wherein a post-separator (10) is disposed downstream of the turbulence chamber (2).

1-10. (canceled)
A crankcase ventilation oil separator for an internal combustion engine, comprising:
- a swirl chamber device including
- a circumferentially extending wall section defining a swirl chamber within, said swirl chamber extending along a longitudinal axis of said swirl chamber device;
- a tangential inlet arranged at an inlet-side end of said swirl chamber device, said tangential inlet introducing a vent gas stream into said swirl chamber producing a swirling action of said vent gas stream around an interior of said cylindrical wall section, said swirling action coagulating oil droplets, separating oil entrained in said vent gas stream;
- a common outlet arranged at an opposing outlet-side end of said swirl chamber device relative to said longitudinal axis, said common outlet in fluid communication with said swirl chamber;
- and
- wherein a said vent gas stream and said coagulated oil droplet exit said swirl chamber device through said common outlet;
- and
- wherein the swirl chamber has arranged downstream thereof a post-separator collecting said coagulated oil droplets.
