KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die in Fig. 1 im Schnitt und in Fig. 2 imThe in Fig. 1 in section and in Fig. 2 in

Grundriß gezeigte Erfindung hat den Zweck, bei dem Rückstauverschluß nach Patent 159822 die Höhe des den Schwimmer aufnehmenden Kastens zu vermindernThe invention shown in plan has the purpose of the backflow stop according to patent 159822 to reduce the height of the box holding the float

Dies ist dadurch erreicht, daß der Schwimmer 2 an der unteren Seite flach, im übrigen keilförmig gestaltet und mit seinem spitzen Ende unmittelbar so mit der gemeinschaftliehen Klappen- und Schwimmerachse 7 verbunden ist, daß die Klappen- und Schwimmerachse 7 möglichst unmittelbar auf oder vor dem eine Strecke unter der Kammer 5 vom Zuflußende her fortgeführten Rohrmantel angebracht werden kann.This is achieved in that the float 2 is flat on the lower side, otherwise wedge-shaped and with its pointed end directly shared with the one Flap and float axis 7 is connected that the flap and float axis 7 as immediately as possible on or in front of a stretch under the chamber 5 from Inflow end her continued pipe jacket can be attached.

Die Vorrichtung wird dadurch bedeutend niedriger und kann bei geringeren Überdeckungen verwendet werden. An dem rückwärtigen Ende des Schwimmers 2 kann . ein Beschwerungsstück 13 angebracht werden. As a result, the device becomes significantly lower and can be used with smaller overlaps be used. At the rear end of the float 2 can. a weighting piece 13 can be attached.

Die Klappe 1 trägt eine Umfangsdichtung 11 und wirkt auf die Stange 12 des der Luft-Öffnung 9 vorgelagerten Luftventils 10.
j . The flap 1 carries a circumferential seal 11 and acts on the rod 12 of the air valve 10 upstream of the air opening 9.
