Abstract

The friction damper, esp. for a washing machine or spin drier, has a friction lining (8) fitted between two axialy displaced limit stops (9, 10) to give a free movement (F) between them. The friction coefficient (R1) between the friction lining (8) and the guide housing (2) is greater than the friction coefficient (R2) between the friction lining (8) and the push rod (1). The lower friction coefficient (R2) is effective only at the oscillating amplitudes within the free movement (F). On oscillating amplitudes which exceed the free movement (F), the larger friction coefficient (R1) comes into effect. ADVANTAGE - The mechanism gives a generally true running for the washing machine or spin drier, with the lowest possible damping. This reduces noise levels within a simple structure.
