Oil separating device for the crankcase ventilation of an internal combustion engine

The invention relates to an oil separating device for crankcase ventilation of an internal combustion engine, comprising a carrier comprising a gas inlet line for flowing blow-by gas having an inlet end and an outlet end, and a gap-defining element, wherein at least one annular gap is formed or can be formed between the gap-defining element and the outlet end of the gas inlet line. A baffle wall is arranged downstream of the annular gap. The oil separating device comprises a circumferential wall, which surrounds the outer circumference of the gap-defining element and is fixed relative to the carrier.
