Abstract
A washing machine having an improved pulsator which includes a skirt, vanes projecting from the skirt, and a shaped projection having a planar surface located eccentrically from the center of rotation of the skirt and extended to a position higher than the vanes. The pulsator rotates in the forward and reverse directions to responsively effect eccentric motion of the projection about the central axis of rotation so that highly turbulent localized water flow is established in conjunction with a vortex flow arrangement to enhance the washing capabilities of the machine.
