The trunks-jets are placed on the front surface of the cover at an angle of 25°-30°, relative to each other along a circular arc. The conical nozzles are mounted in threaded holes having hydraulic connection to the inner cavity of the cover through the water-discharge holes. The diameter of the water-discharge holes is smaller than the inner diameter of the conical sprayers to enable fixing of spiral guides. In the inner cavity of the cover in front of each water-discharge hole there are hemispherical recesses arranged on a circular arc and forming conjugated inlet edges.
