ABSTRACT:
A hydraulic apparatus for a continuously variable transmission by which the rate of changing speed ratios between a driving pulley and a driven pulley is consecutively varied. The apparatus includes a ratio selecting apparatus for changing the speed ratios and a change speed control apparatus for controlling the rate of change of the CVT transmission. The rate of changing the speed ratios is varied by controlling the amount of hydraulic fluid drained through the change speed control apparatus from a hydraulic cylinder, whose pressure is applied to the driving pulley.
