ABSTRACT:
A valve train mechanism for an internal combustion engine in which each cylinder of the engine has a pair of angulated exhaust valves and a pair of angulated intake valves and in which a crosshead is operated by a rocker arm for actuating a pair of same function valves through spherical connections below a pair inverted bucket tappets that are located in a pair of tappet guides for movement along a pair of axes which are inclined towards each other and which lie in a plane extending normal to the rotational axis of the crankshaft of the engine.
