Abstract

Die Erfindung bezieht sich auf einen Stator für einen Exzenterschneckenpumpe oder einen Exzenterschneckenmotor mit einem Stator, der ein Aussenrohr (1) mit einer Auskleidung (2) aus Gummi oder einem gummiähnlichen Werkstoff und einen nach Art eines zwei- oder mehrgängigen Steilgewindes geformten Hohlraum (3) zur Aufnahme eines starren, ebenfalls nach Art eines Steilgewindes geformten Rotors aufweist, wobei das Steilgewinde des Stators jeweils einen Gang mehr aufweist als das Steilgewinde des Rotors. Um einen Stator zur Verfügung zu stellen, der auch unter Bedingungen funktionsfähig bleibt, unter denen die festhaftende Bindung zwischen der Auskleidung (2) und dem Aussenrohr (1) zerstört würde, wird vorgeschlagen, dass in der Auskleidung (2) ein mit Durchbrechungen (5) versehenes Innenrohr (4) angeordnet ist, und dass zwischen Aussenrohr und Innenrohr Abstandsleisten (6) angeordnet sind.
