Abstract
Description
Die vorliegende Erfindung betrifft eine Membran mit den Merkmalen des Oberbegriffs von Anspruch 1.The The present invention relates to a membrane with the features of The preamble of claim 1.
Es
ist bekannt, daß Flachmembranen
zum Beispiel mit Wellenprofil
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Kompensation zu vergrößern und das Arbeitsverhalten der Membran zu verbessern.The The present invention is based on the object of compensation to enlarge and to improve the working behavior of the membrane.
Diese Aufgabe wird von einer Membran nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This The object is achieved by a membrane according to claim 1. advantageous Refinements are the subject of the dependent claims.
Erfindungsgemäß ist vorgesehen, daß die Vielzahl der Scheitellinien oder der Rillen mindestens in einem bestimmt langen Bereich jeweils so ausgerichtet ist, daß dabei dort in dem Verlauf der Scheitellinie der Winkel ein spitzer Winkel konstanter Größe ist, wobei die Scheitellinie oder die Rille in diesem bestimmt langen Bereich sich in einem die Scheitellinie oder die Rille umspannenden Halbkreis erstreckt, dessen Kreismittelpunkt mit dem Zentrum der Membran übereinstimmt und wobei der bestimmt lange Bereich mindestens ein Viertel von der im Halbkreis sich erstreckenden Länge der Scheitellinie oder der Rille im kompensierenden Strukturbereich umfaßt.According to the invention, that the multitude the apex lines or the grooves are determined in at least one long area is aligned so that there in the course the vertex line the angle is an acute angle of constant size, the vertex line or the groove in this determined long area in a semicircle spanning the apex line or the groove extends, the center of the circle coincides with the center of the membrane and wherein the determined long range is at least a quarter of the length of the apex line extending in a semicircle or the groove in the compensating structure area includes.
Der Strukturverlauf hat in dem bestimmt langen Bereich zu der Radialrichtung, dem Scheitelpunkt vom Winkel β, gradmäßig eine gleiche und bestimmte Ausrichtung.The Structure course has in the determined long area to the radial direction, the apex of the angle β, Gradually one same and certain orientation.
Gegenüber den
bisher bekannten Strukturverläufen
von Membranen ändert
sich die bestimmte Gradzahl über
den bestimmt langen Bereich im wesentlichen nicht, während sie
beispielweise nach der
Ein Ausführungsbeispiel der vorliegenden Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.On embodiment the present invention is shown in the drawing and will be closer in the following described.
Es zeigen:It demonstrate:
In
der
Die erfindungsgemäße Membran ist dort geeignet, wo eine große Flexibilität und Kompensation, wie bei gewölbten Membranen zum Beispiel von Speichern und Pumpen gefordert wird.The membrane according to the invention is suitable where a large flexibility and compensation, as with domed ones Membranes, for example, from storage and pumps.
Die mit der Erfindung erzielte vorteilhafte Wirkung kommt dadurch zustande, daß die Kompensation je nach Konstruktion gleichzeitig in einem bestimmt langen Bereich mit dem Winkel gleicher Gradzahl β von 34° oder bis zu 60° arbeiten kann. Ferner, daß die Ausrichtung der Kompensationskräfte auf den Strukturverlauf vorzugsweise gleich bleiben.The advantageous effect achieved with the invention results from that the Depending on the design, compensation is determined simultaneously in one long range with the angle of the same degree β of 34 ° or up to 60 ° can. Furthermore, that Alignment of the compensation forces on the structure course preferably remain the same.
