摩擦振动阻尼器，特别是用于洗衣机用振荡支撑清洗部具有大致筒状的壳体（12）和在该可滑动的柱塞（18）。 在壳体（12）和柱塞（18）的外端部是在每种情况下，提供一种枢转元件（15,19）。 此外，用摩擦衬片在壳体（12）的内壁（27）在所述柱塞上，它是通过线性伺服马达作用的手段膨胀摩擦配合柱塞（25）的形成。 为了实现低成本高操作可靠性，在RAM（18）伺服电机（42）被布置。 它是由可电加热的膨胀材料元件形成，包括壳体（43）具有一个活塞（44）被加热时改变相对于所述壳体（43）的位置。 伺服电动机（42）的活塞（44）直接抵靠摩擦活塞（25）的服务扩展构件（36）的传播。

A frictional vibration damper, particularly for washing machines with a oscillatory support of a washer unit comprises approximately tubular housing (12) and a slidable plunger in this (18). At the outer end of the housing (12) and the plunger (18) is a pivoting element (15,19) is provided in each case. Furthermore, a with a friction lining on the inner wall (27) of the housing (12) is formed friction-fitting plunger (25) on the plunger, which is expandable by means of a linearly acting servomotor. To achieve high reliability with little effort, the control motor (42) is arranged in the ram (18). It is formed by an electrically heatable expansion material element, comprising a housing (43) with a piston (44) which changes its position relative to the housing (43) when heated. The piston (44) of the servomotor (42) is directly opposite a for spreading the friction piston (25) serving to spreading member (36).
