ABSTRACT:
A variable valve timing mechanism for an internal combustion engine wherein the camshaft is supported at one end by a combined bearing and valve body member that is detachably connected to the supporting engine body. The connection is such that fluid from the engine lubricating system can be delivered to this body and distributed by control valves mounted in it. This simplifies machining of the engine body and permits a more compact, lower cost construction without sacrificing any function.
