Abstract
A phase variator including a piston actuator slidable between two travel limit positions as a result of the supply of a flow of pressurized fluid to at least one chamber of the variator. Valves are provided in the variator for choking the flow associated with the at least one chamber so as to avoid axial end contact of the piston and casing and axial end contact of the piston and hub.
