Cylinder head cover for internal combustion engine of motor vehicle, has camshaft rotatively mounted in cover, and vacuum pump, which is integrated to recess formed in cover at end of camshaft that directly drives rotor of vacuum pump

摘要

#CMT# #/CMT# The cover (15) has a camshaft (20) rotatively mounted in the cover, and a vacuum pump, which is integrated to a recess (13) formed in the cover at an end of the camshaft that directly drives a rotor (11) of the vacuum pump. The rotor of the vacuum pump is mounted on an end of the camshaft, and a depression end piece (17) of the vacuum pump is depressed on a cover plate (16). An air duct seal (21) is placed between the cover and the cover plate. #CMT#USE : #/CMT# Cylinder head cover for an internal combustion engine (claimed) of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The utilization of the cover plate on the cylinder head cover allows to use a single air duct seal, thus reducing the encumbrance of the internal combustion engine due to suppression of restraints and reducing the cost and mass of parts to be purchased. The configuration of the cylinder head cover reduces the assembling time of the internal combustion engine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded cavalier view of a cylinder head cover. 11 : Rotor 13 : Recess 15 : Cylinder head cover 16 : Cover plate 17 : Depression end piece 20 : Camshaft 21 : Air duct seal.
