However, many inventors have been attracted by the apparent simplicity and the uniform motion of rotary valves of one kind or another. (the etymology of the word "poppet" is an interesting study in itself, but a bit off-topic) There are good reasons for this see the Appendix on the advantages of the poppet valve. The Almen axial engine The Bristol Axial Engine The Wishon Axial Engine The Butler Compound Engine Page contains sponsored content.įor almost all its history, the preferred valve for the Internal Combustion engine has been the poppet type.
