ABSTRACT:
According to the depicted embodiment, the novel ancillary valve rocker means comprises an ancillary valve rocker which is mountable atop the standard valve rocker, and which has a longer pivot arm, and first and second rods which communicate movement from the standard valve rocker to one end of the ancillary valve rocker, and translate the movement into a greater translation of the valve rod. The first and second rods, secondary push rods, are more widely spaced apart, whereat they engage the ancillary valve rocker than where they engage the standard valve rocker and valve rod end, and this together with the longer "reach" of the ancillary valve rocker causes the valve rod to move through an exaggerated translation. The inventive rocker means are adjustable, whereby the amount of valve rod movement may be selectively determined.
