Abstract

The invention relates to a separator (1) for a crankcase ventilation of an internal combustion engine. The separator (1) comprises at least one swirl chamber (2), which extends along a longitudinal axis (3), wherein said swirl 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 swirl 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 swirl chamber (2).
