VERFAHREN ZU HERSTELLUNG EINES STATORS FÜR EINE EXZENTERSCHNECKENPUMPE UND SICH DARAUS ERGEBENDER STATOR

摘要

The invention concerns a Moineau type gear pump stator (1), comprising a stator cavity with global axial extension inside an elongated body, characterised in that the stator cavity is defined by a rigid-walled metal tubular element (3) having internall the shape and dimensions of the stator cavity such that, when it is assembled with a rotor, a positive clearance with the rotor is obtained.
