Abstract
A cylinder head cover, particularly for covering a cylinder head of an internal combustion engine, having a plurality of functional elements such as an oil filling connection and at least one oil separation device mounted thereon. The cylinder head cover is formed by a bottom shell and a top shell, with the functional elements each being formed from two segments. One segment is integrally arranged on the bottom shell, and the second segment is integrally arranged on the top shell. The two shells are interconnected by communicating sealing contours. Essential functional parts of the oil separation device are provided on the bottom shell and on the top shell. Preferably the functional elements include a cyclone which separates entrained oil from gases in the cylinder head cover and includes a cup arranged on the bottom shell and an immersion tube arranged on the top shell.
