A method for dewatering and/or degassing a hydraulic fluid includes separating gases and water in the hydraulic fluid from the hydraulic fluid by pervaporation at a membrane that is permeable to the gas and the water and that is impermeable to hydraulic fluid, while maintaining a partial pressure drop for the gas and the water near the membrane.

Method for dehydrating and/or degassing hydraulic fluids, device for carrying out said method and use of said device

A friction clutch whereby the operating force characteristic is made largely independent of the wear of the clutch disk. The friction clutch is characterized in that in the engaged position of the clutch, the initial position of a clutch plate corresponding to an initial thickness of the clutch disk corresponds to a stop position of a spring in the direction of a displacement of a pressure plate against the clutch disk, from which the spring produces the superimposed elastic force when the pressure plate is displaced in the direction of clutch disk.
