摘要

A number of embodiments of cylinder head constructions wherein the cylinder head is comprised of a main cylinder head member that slidably supports the valves for the engine, and which has an upper peripheral edge that defines a cam chamber. At least one camshaft and the tappets associated thereby are supported by a separate cam and tappet carrier member that is affixed to the main cylinder head member. Various arrangements are shown wherein one or both camshafts and the tappets associated therewith may be carried by the cam and tappet carrier member and lubricating and fastening variations are also disclosed.
