Title (EN) TOOL FOR SUBMERGED CLEANING OF A SURFACE AND NOSEPIECE FOR SAID TOOL
(FR) OUTIL DE NETTOYAGE SOUS-AQUATIQUE DE SURFACES ET BUSE POUR OUTIL DE NETTOYAGE
Abstract: front page image
(EN)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.
(FR)Selon l'invention, un outil de nettoyage sous-aquatique de surfaces comprend un corps (1) muni d'une poignée (2) et relié à une source (4) de liquide de travail ainsi qu'au moins une buse (6), reliée au corps (1) par une conduite d'amenée (6) et destinée à la formation d'un flux de cavitation. Le canal d'écoulement de la buse (6) est formé par un concentrateur d'admission (15), un tronçon cylindrique droit (16), une chambre de dilatation (17) et un diffuseur de sortie (19). Le corps (14) de la buse (6) comprend deux canaux (20), faits sous un angle par rapport à l'axe longitudinal du canal d'écoulement; ces canaux communiquent avec l'enceinte de la chambre de dilatation (17), et leurs orifices de sortie sont orientés du côté de la sortie du diffuseur (19) dont la surface interne est faite parabolique.
