Abstract
A variable lift cylinder valve system for an internal combustion engine includes a poppet valve operated by a rocker arm which is articulated about a translational pivot having its placement determined by a control shaft which operates a control arm in contact with the translational pivot such that rotation of the control shaft produces translational motion of the pivot so as to control the lift ratio of the rocker arm.
