Abstract
Die Erfindung bezieht sich auf eine Vorrichtung zum Belüften von Wasser mit einem biegsamen Schlauch aus Gummi oder einem gummiähnlichen Werkstoff, der im Wasser angeordnet werden kann und dessen Wandung eine Perforation, feine Schlitze, Durchbrechungen oder dgl. aufweist, über die die Luft in das Wasser austreten kann, wobei in ein Ende des Schlauches ein Rohrstutzen eingeführt ist, über den dem Schlauch Luft zugeführt werden kann. Um den Anschluss für die Luftversorgung in einer für solche Vorrichtungen geeigneten Form auszubilden, die kein Stützrohr aufweisen, wird aufgrund der Erfindung vorgeschlagen, dass das dem Inneren des Schlauches (2) zugewandte Ende (9) des Rohrstutzens (6) flächenhaft ausgebildet ist und in Richtung der Längsachse des Schlauches (2) verläuft, und dass die Wandungen des Rohrstutzens (6) Durchbrechungen (13) zum Durchtritt der Luft aufweisen. The invention relates to a device for aerating water with a flexible hose made of rubber or a rubber-like material, which can be arranged in the water and the wall of which has a perforation, fine slots, openings or the like. Via which the air into the water can emerge, a pipe socket being inserted into one end of the hose, via which air can be supplied to the hose. In order to design the connection for the air supply in a form suitable for devices which do not have a support tube, it is proposed on the basis of the invention that the end (9) of the pipe socket (6) facing the interior of the hose (2) is flat and in Direction of the longitudinal axis of the hose (2), and that the walls of the pipe socket (6) have openings (13) for the passage of air.
