Abstract
The present invention relates to a cylinder head cover for covering a cylinder head of a combustion engine. Such cylinder head covers often comprise an oil separator for separating oil and/or oil spray from the blow-by gas of combustion engines. With the present invention the oil separator is formed as a flow-through tube () through which the gas with the oil and/or oil spray to be separated flows. The flow-through tube () with its longitudinal axis () in the flow-through direction lies essentially in the plane of extension of the cylinder head cover (). A worm-like segment is arranged in the flow-through tube (), and its thread surfaces () form a spiral flow path (). At the same time the cross section of the flow path lies between 1 mm2 and 800 mm2.
