  • Rotation damper with constant friction coefficient
    Patent number: 10378608
    Abstract: A temperature-independent rotation damper 100 is presented. A housing 108 and a piston 102, between which a viscous liquid is located in annular gaps 118, 120, rotate one around the other. When the temperature falls, the damping by the viscous liquid increases. This effect is countered by reducing the effective area which constitutes the braking action, or by enlarging the volume in the annular gaps 118, 120. As the drive, a material having a positive expansion coefficient is used, which material drives a piston 132. In this way, the damping of the rotation damper 100 is broadly practically independent of the temperature.
