Title: OIL MIST SEPARATOR
Abstract:
In order to increase the capacity for separating oil mist from a blow-by gas, a filter element (13) mounted on an oil separator unit (3) is provided with a core (31). The core is a double cylinder comprising an inner cylinder member (34) and an outer cylinder member (35), and a space between the inner cylinder member and the outer cylinder member is used as a separation chamber (36). Nozzles (39) that increase the flow velocity of and emit the blow-by gas are provided to the inner cylinder member. A section facing the nozzles, which is the inner wall of the external cylinder member, is used as a spray surface on which the blow-by gas emitted from the nozzles is sprayed. The core is provided with an oil discharge opening where the oil (OL) that condenses at the spray surface is discharged, and a discharge opening where the blow-by gas is discharged after the oil mist has been separated therefrom.
