1. An aerosol separator (1) for separating aerosols in a blow-by gas, comprising:
at least one feed opening (2) for feeding a blow-by gas provided with aerosols,
an outlet opening (3) for discharging a blow-by gas cleaned of aerosols,
at least one outflow opening (4) for releasing aerosols removed from the blow-by gas, and which is arranged between a flow path (5) of the at least one feed opening (2) and the outlet opening (3), and
a plurality of projections (6) for configuring the flow path (5) running from the at least one feed opening (2) to the outflow opening (4) in a meandering manner, to decelerate the blow-by gas which enters the feed opening (2) and which is provided with aerosols, in terms of its flow rate, wherein
the projections (6) in their end region (61), around which blow-by gas flows, have a portion with increasing projection width (62).
