Working fluid tubes are mounted into bottom of outer sleeve. Jet spray forming member is defined by cavity of inner sleeve made in the form of truncated cone serving as diffuser. Air nozzle is defined by radial gap between plug and upper part of inner sleeve cavity. Sleeves are rigidly connected with one another. Shaft is positioned for rotation from electric engine mounted on frame and for reciprocation by means of hydraulic cylinder.
