WASHING MACHINE ACTUATOR Russian patent published in 2015 - IPC D06F37/00 

FIELD: machine building.

SUBSTANCE: claimed mechanism is a mechanical gearing. Working surface of its case 1 is composed by epitrochoidal outline 2. The latter is delineated by vertices 5 of three-angle rotor 4 with crank 6 offset relative to common cup 7. Axis of the latter is aligned with the centre of epitrochoidal outline 2. Radii of cup 7 and cranks relate as 2:3 while eccentricity makes half the radius of cup 7. Note here that axial evolution of case 1 represents an epitrochoidal in-chamber surface 3. Bottom half of the latter is a mesh in horizontal level of outline 2. Cup 7 makes the driving link of said mechanism while side working surfaces of rotor 4 vertices 5 and crank 6 boundary circumference are provided with plastic ribs 8.

EFFECT: higher operating performances.
