Abstract
An axial setting device for loading the friction plates of a coupling or for fixing the viscous plates of a coupling having two parts which are co-axially supported on a fixed housing and which are rotatable relative to one another. A pump assembly has housing parts that are connected to the one of the coupling parts and whose conveying elements are connected to the other one of the coupling parts in such a way that, when the parts rotate relative to one another, fluid is conveyed in the pump assembly. A reservoir is provided for fluid with a variable volume and a pressure chamber is delimited by an axial piston. A fluid connection is made from the reservoir to the chamber via the pump assembly and a fluid connection is made from the chamber to the reservoir via a bypass line with a solenoid valve.
