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 forming an annular space having inlet and outlet apertures appropriately positioned with respect to the weights, such that the latter act as vanes in the annular space to produce ventilation outwardly through the outlet apertures.
