<p>The inventive tool for submerged cleaning of a surface comprises a body (1) which is provided with a handle (2) and connected to a working fluid supply unit (3), and at least one nosepiece (6) for producing a cavitating fluid flow connected to the body by means of a feeding pipeline (5). A running channel of the nosepieces (6) is formed with the aid of an inlet contractor (15), an expansion chamber (17) and an outlet diffuser (19). At least two channels (20) are embodied in a body (14) of the nosepiece (6) at an angle to a longitudinal axis of the running channel. Said channels (20) are linked to a cavity of the expansion chamber (17) and the outlets thereof are directed towards the outlet of the diffuser (19) whose inner surface is embodied in the form of a parabola.</p> |
