Abstract
A frictional damper, includes a circular-cylindrical casing and a ram which is coaxially displaceable in the casing and the inner end of which is provided with a cylindrical friction piston. On its external face, the friction piston is provided with one or more friction elements which are elastically pressed against the inner wall of the casing. To obtain a uniform surface pressure over the entire friction surface of the friction element or elements during the entire life of the frictional damper, the friction piston is provided with a bushing having a circular-cylindrical external shape and of counter-holder flanges or disks which project radially from the bushing and delimit the latter at a fixed axial extent. Moreover, at least one annular-cylindrical friction sleeve which has a closed circumference, is made of an elastically yielding material and is under tension in its inner circumferential zone, is provided on the bushing. The damper is particularly useful for damping washing machines which have a spinning mode.
