Abstract (en)
[origin: WO2021078394A1] The present disclosure relates to a laundry washing machine (1) comprising a rotatable drum (11), and a suspension arrangement (17,19) devised to carry the drum (11) in relation to a base structure (5), located under the washing machine and on which the washing machine rests, wherein the suspension arrangement comprises at least one piston damper (33). A speed sensing arrangement is provided, determining the rotating speed of the drum, and the piston damper 33 comprises a clamp arrangement (35,37), devised to decrease its friction, based on a determined rotating speed and by means of the clamp arrangement, when the rotating speed increases, reaching a threshold value. Thereby suitable damping can be provided both at high and low speed.
