Cylinder head cover for a cylinder head of an internal combustion engine

Abstract

A cylinder head cover for a cylinder head of an internal combustion engine having a gasket element between the cylinder head and the cylinder head cover in which the gasket element includes a vacuum chamber which is open on at least one side and produces a seal between the cylinder head cover and the cylinder head when a vacuum is applied.

1 . A cylinder head cover for a cylinder head of an internal combustion engine with a gasket element between the cylinder head cover and cylinder head, wherein the gasket element is associated with a sealing surface on the cylinder head or the cylinder head cover, and the gasket element comprises a vacuum chamber which is open on at least one side, the open side of the vacuum chamber facing the associated sealing surface on the cylinder head or cylinder head cover.  
   
   
       2 . A cylinder head cover according to  claim 1 , wherein the gasket element comprises at least one lip-shaped profile gasket for sealing the vacuum chamber of the gasket element to the associated sealing surface.  
   
   
       3 . A cylinder head cover according to  claim 1 , wherein at least one fixation element is provided for fixing the cylinder head cover on the cylinder head.  
   
   
       4 . A cylinder head cover according to  claim 1 , wherein the gasket element is mounted on one of the cylinder head and cylinder head cover; the associated sealing surface is on the other of the cylinder head and cylinder head cover, and the vacuum chamber is in contact with said sealing surface.  
   
   
       5 . A cylinder head cover according to  claim 1 , wherein the cylinder head cover comprises a circumferential web which is received in a slot or groove in the gasket element.  
   
   
       6 . A cylinder head cover according to  claim 5 , wherein the vacuum chamber of the gasket element is open toward the web as well as toward the sealing surface on the cylinder head, and the circumferential web engages at least partially in the vacuum chamber.
