ABSTRACT:
A variable diameter pulley including a pair of pulley flanges axially displaceable one relative to the other, centrifugally responsive weights acting on one flange to cause axial displacement thereof, a pusher ring interposed between the actuating weights and the axially displaceable flange, a drive device transmitting the rotation to the weights and the axially displaceable pulley flange. This variable diameter pulley is characterized by providing the pusher ring with opposite faces of dissimilar radial contours to selectively set the ring for engagement of the weights with a selected one of the contours and thus obtain a corresponding rate of axial action in the displaceable pulley flange.
