Stator for an eccentric gear pump or a motor worm eccentric operating on the principle Moineau and method to produce it.

摘要

"The stator for an eccentric gear pump or a motor worm eccentric operating on the principle Moineau".The present invention relates to a stator for an eccentric gear pump or a motor worm eccentric, including an outer tube which is provided with a lining of rubber or a similar material to rubber and has a hollow space or cavity, in the shape of a spiral dual or multiple, P. To accommodate a rigid rotor which is also in the form of a spiral.By means of the stator has a spiral of the engine. So that the stator also remain functional under conditions where the fixed connection between the lining and the outer tube can be destroyed, for example, due to the influences of chemical or high temperatures, the invention proposes to have two inner pipes which have openings in the lining.
