Abstract

Die Erfindung bezieht sich auf eine Anordnung des Stators (1) von exzentischen Spiralpumpen, dessen Material elastomer ist und dessen Innenfläche (B) über Gewindeprofil mit zwei oder mehreren Anschnitten verfügt. Die äußere Mantelfläche des Stators ist eine Polygonfläche, und der Stator ist durch eine Metallhülse (2) umnommen, deren innere Mantelfläche sich an der äußeren Mantelfläche des Stators anpaßt, und die mit mindestens einer Aufschlitzung aufgeschnitten ist. The invention relates to an arrangement of the stator (1) of eccentric spiral pumps, the material of which is elastomeric and the Inner surface (B) via thread profile with two or more gates disposes. The outer lateral surface of the stator is a polygon surface, and the stator is encased in a metal sleeve (2), the inner one The outer surface conforms to the outer outer surface of the stator, and which is cut open with at least one slit.
