PULSATOR Russian patent published in 2019 - IPC F15B21/12 

FIELD: machine building.

SUBSTANCE: invention relates to power engineering, in particular to methods of flushing out circuit systems of nuclear steam generating units. Pulsator comprises tight housing and shaft rotating from motor-reducer 10. Housing is installed vertically and comprises cylindrical shell, bottom and cover, between which coaxially to axis of shell is mounted in bearing supports shaft, rotating in one direction from motor-reducer 10, arranged on outer side of cover. Two symmetrical blades are secured on the shaft. At the bottom there is a drain hole, to which drain pipeline 14 is connected. Between the inner walls of the shell and the outer edges of the blades there is a gap for sealing and adjustment of which along the perimeter of each blade detachable seals are fixed at an angle from the front plane of each blade to the rear one in the direction opposite to their rotation. On the outer side of the housing at equal distance along the perimeter and height there installed are four mutually perpendicular pipes 5 with flanges 6, which provide 4-fold change of direction of liquid movement in the flushed product per one revolution of the shaft.
