Title: LIQUID MIST SEPARATION DEVICE
Abstract:
The invention relates to a liquid mist separation device for separating liquid from a gas flow (14), in particular oil from blow-by gas, having a nozzle plate (16), which has at least one nozzle (18), which is permanently open at least in part, and through which the gas flow (14) flows, having at least one baffle plate (20) arranged opposite the at least one nozzle (18), which baffle plate deflects the gas flow (14) and on which liquid droplets precipitate. In order to reduce the pressure loss, according to the invention the liquid mist separation device (10) has at least one valve element (25) which, together with the nozzle plate (16), forms at least one variable nozzle (26) having a variable nozzle cross-section, the at least one variable nozzle (26) is arranged fluidically parallel to the at least one nozzle (18) of the nozzle plate (16), and the nozzle plate (16) and the valve element (25) are arranged so as to be axially displaceable relative to each other.
