Abstract

A hollow body includes an integrated oil separator unit, a swirl generator located in a cavity of the hollow body, at least one first 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 for carrying away gas that has been cleaned of oil. The swirl generator also has elements that are used to variably influence the pressure prevailing at a predetermined point in the cavity.
