ABSTRACT:
A cylinder head for an internal combustion engine is constructed with a camshaft holder assembly. The camshaft holder assembly consists of several cylindrical recesses which form the camshaft support bearing, the camshaft positioning guide, and an accommodating chamber. Lubricant flows through the camshaft support bearing and accumulates in the accommodating chamber, which encloses a coupling between the camshaft and the drive shaft of an auxiliary device, for lubricating and cooling the coupling. The lubricant is maintained at a relatively constant level in the accommodating chamber by an inclined flow passage to the lubricant return passage in the cylinder head and the splashing action of the coupling within the accommodating chamber.
