Abstract
An oil mist separator (10) for a crankcase ventilation (11) such as in an internal combustion engine (13) for separating oil particles from a gaseous fluid, in particular blow-by gas is disclosed. The oil mist separator (10) has at least one nozzle plate (24). The at least one nozzle plate (24) is arranged in a flow way of the gaseous fluid. The nozzle plate (24) has at least one aperture (26; 126) for the gaseous fluid. The oil mist separator (10) further has at least one impact surface (32; 132). The at least one impact surface (32; 132) is arranged downstream of the nozzle plate (24) relating to the flow of the gaseous fluid. The at least one impact surface (32; 132) can be moved away from the at least one nozzle plate (24) in an opening direction (36) against a pretension force by influence and dependent on a flow of the gaseous fluid through the at least one aperture (26; 126). At least one aperture is formed as a nozzle aperture (26) and at least one control protrusion (42; 142) for controlling the flow cross-section of at least one aperture (26; 126) is attached to at least one impact surface (32).
