Abstract

  • 2.1 Der Erfindung liegt die Aufgabe zugrunde, eine ölfreie Pumpe der eingangs genannten Art anzugeben, die eine lange Laufzeit ermöglicht, kostengünstig herstellbar ist, und für die Miniaturisierung geeignet ist.
  • 2.2 Erfindungsgemäß gelingt die Lösung der Aufgabe dadurch, dass der Pumpenkörper eine zylindrische Innenwand mit mindestens einer seitlicher Einlassöffnung und mindestens einer seitlicher Ausstoßöffnung aufweist, in dem eine aus einem zylinderförmigen flexiblen Membrankörper bestehende Membran angeordnet ist, wobei sich im mittleren Bereich des Membrankörpers eine bewegliches nichtdehnbares Band befindet, die Enden des Membrankörpers dicht mit dem Pumpenkörper verbunden sind und im Inneren des Membrankörpers ein Walzenkörper, in dem Drehschieber angeordnet sind, drehbar angebracht ist.
  • 2.3 Die Erfindung betrifft eine ventillose Pumpe mit einer an einem Pumpenkörper angeordneten Membran.
