A liquid mist separation device for separating liquid from a gas flow may include a nozzle plate including at least one nozzle which is open at least in part and at least one baffle plate. The device may also include at least one valve element which, together with the nozzle plate, forms at least one variable nozzle. The at least one variable nozzle may be arranged fluidically parallel to the at least one nozzle. The nozzle plate and the at least one valve element may be arranged axially displaceable relative to each other. The nozzle plate and the at least one baffle plate may be disposed at a fixed distance with respect to one another. Opposite the at least one nozzle and the at least one variable nozzle a baffle plate may be arranged, which deflects the gas flow emerging from the respective nozzle and on which liquid droplets precipitate.

A vehicle may include an internal combustion engine having a crankcase and a supercharging apparatus, and a crankcase ventilation apparatus having at least one oil-separating apparatus including at least one oil separator. An oil return line may communicate separated oil from the crankcase ventilation apparatus to the crankcase. An ejector pump may be driven via a compressed air flow of the supercharging apparatus and may be configured to generate an underpressure for driving a blow-by gas. The crankcase ventilation apparatus may include a pump control valve configured to at least one of regulate and control the compressed air flow through the ejector pump.
