Abstract
A PCV valve is incorporated in the interior of a centrifugal oil mist separator which is provided integrally on a head cover of an engine. The centrifugal oil mist separator comprises an upstream-side separation chamber including a blow-by gas inlet port and a downstream-side separation chamber to which a blow-by gas outlet port and an oil discharge hole open, and an oil separation plate is disposed such that a communication between the blow-by gas inlet port and the blow-by gas outlet port is cut off. The oil separator plat is provided at a distal end of a protruding portion which integrally extends from a valve seat of the PCV valve, the protruding portion and the oil separation plate functioning to intensify a swirl flow in the upstream-side separation chamber.
