From section BB it can be seen that a mechanism comprising an eccentric
in a scotch yoke slides vertically in the two-piece casting that forms not only
the housing but also the driveshaft bearings and caps.Rotation of the control
shaft moves the whole assembly laterally,and therefore the driveshaft into
and out of concentricity with the camshaft sections.The control shaft can be
rotated through only 90° which is why,when it has been actuated to bring the
driveshaft into its eccentric position,as in section BB,there is no clearance
above the scotch yoke.
By arranging the belt or chain drive as in Fig.3.26,lateral movement of
the driveshaft can be made to cause also a phase change.The resultant
changes of the valve timing are illustrated in Fig.3.34,which shows what
the lift characteristics are with the standard timing,what they would be if
only event timing were changed and what it is when both event timing and
phase shift are
