ABSTRACT:
A valve arrangement for an internal combustion engine that permits the use of a plurality of closely spaced valves. The valves are all directly actuated by means of thimble tappets that have non-cylindrical cross-sections so as to permit the tappet bodies to be positioned close to each other and yet afford a large area for their sliding support. The tappet bodies are also supported within the cylinder head assembly by means including a separate insert.
