Abstract

D ispositif de générat ion de courant pour une piscine Le dispositif (10) de génération de courant pour une piscine comprend un corps (12) cylindrique et un guide flux (14) creux, le guide flux (14) étant pourvu d’au moins une ouverture (18) d'entrée de liquide et d’au moins une ouverture (20) de sortie de liquide, dans lequel l’ouverture (20) de sortie est pourvue d’une grille (26) munie d’une pluralité d’ailettes (28) pour orienter l’écoulement de liquide, les ailettes (28) ayant une section en forme de goutte avec un bord d’attaque (30) orienté vers l’amont et un bord de fuite (32) orienté vers l’aval du dispositif (10, 10’), dans lequel chaque ailette (28) présente un rapport Cx d’une épaisseur maximale (e) sur une longueur ou corde (l) compris entre 0,24 et 0,30, plus particulièrement sensiblement égal à 0,27. Figure pour l'abrégé : Figure 1Current generation device for a swimming pool The current generation device (10) for a swimming pool comprises a cylindrical body (12) and a hollow flow guide (14), the flow guide (14) being provided with at least a liquid inlet opening (18) and at least one liquid outlet opening (20), in which the outlet opening (20) is provided with a grid (26) provided with a plurality of fins (28) for directing the flow of liquid, the fins (28) having a drop-shaped section with a leading edge (30) oriented upstream and a trailing edge (32) oriented downward downstream of the device (10, 10'), in which each fin (28) has a ratio Cx of a maximum thickness (e) over a length or chord (l) of between 0.24 and 0.30, more particularly substantially equal to 0.27.
