ABSTRACT:
The valve operating mechanism includes an L-shaped rocker arm having a cam follower surface on one leg composed of a straight section and a curved section acted upon by a cam on a rotatable camshaft. The other leg of the L-shaped rocker arm contacts a valve member to open the valve member, overcoming the spring closing force to do so. A lever arm has one end mounted for pivotal movement about a shaft providing a fixed axis, a pin carried by said lever arm intermediate said one end and the other end thereof providing a shiftable axis. A base circle feature is included by means of a pair of curved edges adjacent opposite sides of said straight section. The curved section provides an increased amount of valve opening, the curved section curving sufficiently to provide a semi-desmodromic valve operation desirable during maximum valve lift at high engine speeds.
