Abstract

The cylinder head cover is formed from a lower shell (11) and an upper shell (12) joined at a sealing interface (14). The functional elements are in the form of two segments, one integrated into the lower bowl, and the other into the upper bowl. Essential functional parts of the oil separator are fitted to the upper and lower shells. These include the vessel (16) and immersion tube (15) of a cyclone.
