Abstract: A damper for damping movements of a wind turbine, in particular for damping oscillatory movements of a tower of the wind turbine is provided. The damping of the movements is achieved by an aqueous liquid contained in a container of the damper. The aqueous liquid includes water and the components included in the aqueous liquid are completely dissolved. The composition includes a citrate, e. g. potassium citrate and/or sodium citrate. A wind turbine including the damper is also provided. Finally, a specific composition is provided. The composition is destined to be dissolved, e. g. in water, to result in the aqueous liquid.

Abstract: A brake device for a hydraulic motor vehicle brake system without a vacuum booster, with a housing with at least one pressure chamber arranged therein, with a cylinder piston which can be axially moved in an actuation direction by an actuating rod unit coupled to the cylinder piston in order to generate brake pressure, wherein a rigid stop is provided for the cylinder piston which defines the non-actuated starting position of the cylinder piston. In order to provide an improved brake device of the above-mentioned type, which permits simple and reliable detection of the zero point and simultaneously has reduced noise emission on the return, a damping element is provided which permits a mechanical decoupling of the actuating rod unit from the cylinder piston in a release direction opposite the actuation direction by reversible deformation.
