Abstract

A centrifugal separator for separating oil from a gas stream, particularly for venting the crankcase of an internal combustion engine, having a housing (2) in which the flow guiding means are arranged. The flow guiding means are connected to a drive shaft (3). A gas inlet (5) opens into the housing (2), and a gas outlet (6) and an oil outlet (7) lead out of the housing (2). An easily produced and functionally reliable arrangement is obtained if the housing (2) is non-rotatably mounted and an impeller (14) with blades (11) that produce a centrifugal flow is disposed in the housing (2) such that it is rotatable about the longitudinal axis (4) of the drive shaft (3).
