PULSATOR Russian patent published in 2014 - IPC F15B21/12 

FIELD: machine building.

SUBSTANCE: pulsator comprises a casing with sealed pulsation chambers 1, where motor-driven shafts 2 with discs rigidly fixed on them are mounted coaxially to the chambers. The casing consists of 4 vertically set cylindrical pulsation chambers 1 that are communicating and are symmetrically set on mutually perpendicular axes in plan view. The chambers 1 are connected pairwise by two parallel upper branch pipes and perpendicular to them - by two parallel lower branch pipes. The discs are installed at an angle to the shafts 2 in their central part so that their upper edge is below the upper branch pipe and the lower edge is above the lower branch pipe. External branch pipes 8 are mounted at the casing diagonals on the outer side of every chamber at half of their height.

EFFECT: increased efficiency of item washing.
