[origin: EP1428926A2] A washing machine is provided with a drain pump comprising a synchronous motor and an impeller (2); the shaft (1) of the motor is provided with an appropriate flywheel (33) and has an eccentric protrusion (4) at the extremity thereof, and said impeller, in its central zone where it is fitted onto said shaft, is provided with a ring-shaped (5) cavity extending circularly only along a definite arc portion (A) and adapted to accommodate said eccentric protrusion. This eccentric protrusion is in turn so sized with respect to said cavity as to be capable of freely rotating for a pre-definable arc (B) within said cavity.
