Abstract

1335412 Cams USTAV PRO VYZKUM MOTOROVYCH VOZIDEL 19 April 1971 [27 July 1970] 23832/71 Heading F2K A tappet lift cam designed to reduce noise in operation and to increase its life has a plurality of regions of which the first from the non-lift point N has an equation corresponding to a straight line, a sine curve, or a parabolic curve while the second region lift curve equation has a second differential which is curved and a third differential which is zero at the transition point between the first and second regions. Preferably the second differential of the equation of the second region also has zero value at the transition point between the first and second regions.
