Title (EN) ANTI-CLOGGING, VARIABLE THROAT SUCTION NOZZLE AND SUCTIONCLEANING DEVICE EQUIPPED THEREWITH
(FR) BUSE D'ASPIRATION ANTI-OBSTRUCTION A ETRANGLEMENT VARIABLE ET APPAREIL DE NETTOYAGE PAR ASPIRATION EQUIPE DE CETTE BUSE
Abstract:
(EN) A suction nozzle (28) adapted for use in a suction cleaning device (10), such as an automatic swimming pool cleaner, includes a body (30) having a throat (32) extending from an inlet (24) at one end of the body (30) to an outlet (34) at an opposite end of the body (30). The body (30) itself is split longitudinally into a plurality of discrete body portions (36, 38) to form the throat (32) of the nozzle (28). One body portion (38) is movable relative to the other body portion (36), whereby the throat (32) automatically expands in response to the relative movement of the body portions (36, 38). The resulting expansion of the nozzle (28) allows substantially unrestricted passage of large foreign objects (B) through the throat (32) during the operation of the suction cleaning device (10).
(FR) La présente invention concerne une buse d'aspiration (28) conçue pour être utilisée dans un appareil de nettoyage (10) par aspiration tel qu'un nettoyeur automatique de piscine. Cette buse est constituée d'un corps (30) doté d'un étranglement (32) qui s'étend depuis un orifice d'entrée (24) situé sur l'une des extrémités du corps (30) jusqu'à un orifice de sortie (34) situé sur l'extrémité opposée du corps (30). Le corps (30) lui-même se décompose en plusieurs parties constitutives distinctes (36, 38) formant l'étranglement (32) de la buse (28). Une partie du corps (38) est mobile par rapport à l'autre partie du corps (36), de façon que l'étranglement se détende automatiquement en réaction au déplacement relatif des parties du corps (36, 38). L'expansion résultante de la buse (28) autorise un passage sensiblement illimité de gros corps étrangers (B) par l'étranglement (32) pendant le fonctionnement de l'appareil de nettoyage (10) par aspiration.
