Patent ID: 7434572

Claim:
A cylinder head ( 1 ) of an internal combustion engine, comprising a camshaft bearing mechanism ( 2 ) arranged on the cylinder head ( 1 ), a hollow camshaft ( 3 ) that is rotatably mounted in the camshaft bearing mechanism ( 2 ) and forms an outlet for blow-by gases laden with oil droplets out of the crankcase and is designed as an oil droplet separator for separation of the oil content out of these gases, whereby the camshaft ( 3 ) passes through a valve space ( 11 ) containing the camshaft bearing mechanism ( 2 ), whereby a rocker cover ( 13 ) or a multichannel device ( 27 ) is connected axially at at least one end to the camshaft ( 3 ) forming an axial gap ( 9 ), each having a channel ( 10 ) connected coaxially to the hollow space ( 5 ) of the camshaft ( 3 ) through which blow-by gases from which the oil has been removed can be discharged from the camshaft ( 3 ), whereby the rocker cover ( 13 ) or the multichannel device ( 27 ) is designed so that it either forms an oil collecting space ( 12 ) that is sealed with respect to the valve space ( 11 ) or it introduces separated oil into such an oil collecting space ( 12 ).
