Abstract

A hollow body, in particular a camshaft, is provided. The hollow body includes an integrated oil separator unit, a swirl generator being located in a cavity of the hollow body and the hollow body having at least one supply opening in the camshaft case for introducing gas that is charged with oil into the cavity and at least one discharge opening for carrying away separated oil and gas that has been cleaned of oil. The hollow body has an oil separator ring inside the cavity, downstream of the swirl generator when viewed in the flow direction.
