Abstract
In this variator pulley, the movable flange plate (15A) is subjected to a diaphragm (26A) which is at least partially sealed and of which the supports on the movable flange plate (15A) and the corresponding support piece (30A) are themselves at least partially sealed. According to the invention, the chamber (38A) jointly formed by the movable flange plate (15A), its hub (12A), the diaphragm (26A) and the support piece (30A) of the latter is at least partially sealed and thus itself constitutes a regulating chamber designed to be connected to any pressure source for regulating the assembly of the whole. The invention is used, in particular, for speed variators intended for equipping motor vehicles.
