Description

Das Patent 831 797 betrifft eine Pumpeinrichtung zum Konservieren von Einmachgut, die aus einer mit einem automatischen Auslaßventil versehenen Kammer besteht, die mit einer veränderlichen Wand, Membran oder einem Kolben ausgestattet ist.Patent 831,797 relates to a pumping device for preservation of preserves coming out of a chamber equipped with an automatic exhaust valve composed of a changeable wall, membrane or piston is.

Eine dehnbare oder balgenartig gefaltete Membran nutzt den höchsten Wirkungsgrad der Pumpe nicht aus. Der Sog einerseits und der Druck andererseits bewirken ein Nachgeben der Membran im Sinne einer Verkleinerung des Wirkungsgrades im Verhältnis der Dehnbarkeit der Membran. Durch die Erfindung ist die Dehnbarkeit, bei idealer Lösung, gänzlich ausschaltbar, bei Verwendung von dehnbarem Material mindestens in hohem Maße zu verringern.A stretchable or bellows-like folded membrane uses the highest Pump efficiency not sufficient. The pull on the one hand and the pressure on the other cause the membrane to yield in the sense of a reduction in efficiency in relation to the elasticity of the membrane. With the invention, the extensibility, with the ideal solution, can be completely switched off, when using stretchable material at least to a large extent.

Hierdurch wird ein wesentlich höherer Nutzeffekt erzielt. Das Vakuum- wird größer. Diese Verbesserung hat außerdem den Vorteil, daß die Bechermembran im Gegensatz zu der dehnbaren flachen Membran der das Gerät benutzenden Person keinen Widerstand mehr entgegensetzt, so daß das Spannen der Pumpe wesentlich erleichtert wird.This results in a significantly higher efficiency. The vacuum becomes larger. This improvement also has the advantage that the cup membrane in contrast to the stretchable flat membrane of the person using the device, none Resistance more opposed, so that the tensioning of the pump much easier will.

Eine weitere Verbesserung der Membran ist darin zu sehen, daß dieselben einen zylindrischen oder auch winklig abgebogenen Rand aufweist und daß die Randl@ante mit einer Wulst versehen ist.A further improvement of the membrane can be seen in the fact that the same has a cylindrical or angled edge and that the Randl @ ante is provided with a bead.

Hierdurch ist es möglich, die Membran zwischen entsprechenden Flächen der Pumpe einzuspannen, ohne daß die Membran durch Anbringung von Löchern-geschwächt wird. Die Wulst verhindert ein Herausgleiten der gespannten Membran aus den dieselbe haltenden Bauelementen.This makes it possible to place the membrane between corresponding surfaces to clamp the pump without the membrane weakened by making holes will. The bead prevents the tensioned membrane from sliding out of the same holding components.

Abb. r zeigt die Membran f in der Stellung des größten Kammervolumens, d. h. bei hochstehendem Bolzen und entspannter Feder nach Patent 831797. Fig. R shows the diaphragm f in the position of the largest chamber volume, ie with the bolt upright and the spring relaxed according to patent 831797.

Abb. 2 zeigt die Membran f in etwa falb heruntergedrückter Stellung des Bolzens, während Abb. 3 die Membran bei völlig heruntergedrücktem Bolzen zeigt.Fig. 2 shows the membrane f in an approximately fallow depressed position of the bolt, while Fig. 3 shows the membrane with the bolt fully depressed.

Als Material, welches eine gute Beweglichkeit der Membran bei geringstem Dehnungsfaktor desselben besitzt, kommen sowohl Polyvinylverbindungen, Folien aus regenerierter Cellulose u. dgl. als auch gummiertes Gewebe in Betracht. _As a material, which a good mobility of the membrane with the lowest Has the same expansion factor, both polyvinyl compounds and foils can do regenerated cellulose and the like as well as rubberized fabric. _
