Abstract
A drum type clothes washing machine includes a housing, an outer tub mounted by springs in the housing, and a washing tub mounted in the outer tub for rotation relative thereto about a horizontal axis. A vibration attenuation apparatus includes a pair of chambers fixed to an underside of the outer tub. The chambers contain a liquid and communicate with one another. A motor drives the washing tub. A pump is also driven by the motor for transferring liquid from one chamber to the other for compensating for a shifting of the axis during rotation of the washing tub.
