Abstract

The positive displacement pump has a cylindrical stator, inside which rotates a cylindrical rotor on an axis eccentric to the stator centre. The rotor is supported by a peripheral needle roller bearing, while a flexible tube is wound in a spiral round the rotor. O(e or more elastic annular packings (11a, 11b) are inserted between the outside surface of the rotor (1) and the flexible tube (8). The outside of the rotor can be smaller by a few tenths of a millimeter than the internal diameter of the inner bearing race, one or more compressible packings being inserted between them.
