Abstract
In an oil separator designed as an electrostatic filter with a one-piece discharge electrode and a collecting electrode, said separator being located in the vent line of a crankcase ventilation system for an internal combustion engine, the invention proposes that the spray electrode be made in two stages, with a first stage having a small cross-sectional area and a second stage having a cross-sectional area that is larger than that of the first, and with the spray electrode tapering from the cross-sectional area of its second stage to the smallest cross-sectional area of its first stage, and with the first stage being made in the shape of a cone and having a base that adjoins the second stage and a freely terminating tip.
