Un tube coulissant est pourvu d'un corps flottant, moyennant quoi un orifice d'aspiration de gaz-liquide dans lequel des lames sont torsadées à la pointe dans une direction est constamment maintenu à la surface de l'eau, ledit tube coulissant étant ajusté de manière lâche à la périphérie externe à l'extrémité d'un tube de mélange gaz-liquide, une protubérance et une partie découpée permettant d'empêcher la rotation étant adaptées l'une à l'autre. L'orifice de décharge d'un tube d'introduction est inséré au niveau d'une position appropriée dans le tube de mélange gaz-liquide, qui possède un tube courbé de diamètre supérieur. Plusieurs plaques de guidage de tourbillons présentant une surface incurvée modérée sont réunies dans l'espace et sont inclinées par rapport à la direction axiale dans le même sens que la torsion dans les pales. L'orifice de décharge du tube de mélange gaz-liquide est inséré dans une section d'extrémité d'un tube de décharge de gaz-liquide, qui possède un tube incurvé présentant un diamètre supérieur, dans une position appropriée dans un orifice d'aspiration inférieur disposé de façon à être de forme semblable à l'orifice d'aspiration de gaz-liquide. Plusieurs plaques de guidage de tourbillons présentant une surface courbe modérée sont reliées dans l'espace d'introduction résultant et sont inclinées par rapport à la direction de l'axe du tube dans la même direction que la torsion dans les pales à l'orifice d'aspiration inférieur. Un trou de purge d'air 19 est prévu au niveau de la partie la plus haute du tube de décharge de gaz-liquide.
