Authors Abstract
Content
THIS paper calls attention to some of the shortcomings of parts that are and have been in a continual state of change for many years, possibly more so than most other parts in an internal combustion engine.
Little is said of inlet valves in comparison with exhaust valves because they generally are fairly satisfactory so far as tight seating is concerned, but they are open to the same improvements as to spring-locking devices as exhaust valves are.
The principal essentials for exhaust valves are stated and commented upon, the shape a valve head on the exhaust side should have is discussed, and cylinder and valve-guide design are considered.
The use of no-lash hydraulic-type tappets is advocated because they keep quiet the numerous wearing joints in an overhead-valve operating-mechanism. In conclusion, the authors state eight specific points that an ideal engine should have with respect to its valves and their related parts.
