Abstract:
A friction damper for washing machines, comprising a hollow shell and a rod, coaxially arranged with respect to one another and forming a telescopic motion construction, said rod having an outer diameter less than an inner diameter of said shell, rod guiding means arranged between said hollow shell and rod, a friction damper element, arranged between said rod and hollow shell in a space delimited by a pair of top and bottom resilient means, said damper element comprising a substantially cylindric holding bushing having a throughgoing axial hole and fitted about said rod, said bushing having an inner surface and an outer surface in which seats are formed for housing a first friction clamp and a second friction clamp, said first and second friction clamp being arranged concentrically, said first friction clamp having a first working surface frictionally engaging an outer surface of said rod and said second friction clamp having a second working surface frictionally engaging an inner surface of said hollow shell, wherein said first working surface is larger that said second working surface thereby said first working surface provides against said rod a friction reaction greater than a friction reaction provided by said second working surface against said hollow shell.
