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