Abstract

The invention concerns an oil separator (2) for crankcase gases of an internal combustion engine, comprising a preliminary separator (28), a cyclone separator (30), a fine separator (32) and, if necessary, a valve device (36) that are provided in a cascade arrangement on a cylinder-head cover (4) of the internal combustion engine; in order to create an oil separator for use in various engines having different quantities of crankcase gas, said oil separator is designed so that, as an option, helixes (48) having different radial depths of the flow path can be inserted in a housing section for the cyclone separator (30).
