ABSTRACT:
In a venting arrangement for a crankcase of an internal combustion engine including a centrifugal separator having a rotatable housing with an inlet channel for the admission of an oil-air mixture and an exit channel for the discharge of air from which the oil has been removed, the inlet channel extends essentially in a direction parallel to the axis of rotation of the housing, but in spaced relationship from the axis so that oil which has been separated from the oil-air mixture moves, subjected to centrifugal forces, radially outwardly at a 90.degree. angle to the generally axial oil-air mixture flow through the separator.
