The invention relates to a stator for an eccentric spiral pump or an eccentric worm motor with a stator, comprising an outer tube with a rubber covering or covering made of a rubber-type material and a cavity formed in the manner of a twofold or multiple steep thread for receiving a rigid rotor also formed in the manner of a steep thread. The steep thread of the stator respectively comprises one thread more than the steep thread of the rotor. According to the invention, an inner tube provided with openings is arranged inside the covering and distance strips are arranged between the outer and inner tube in order to provide a stator which remains operational during certain conditions when the adhesive bond between the fitting and outer tube is destroyed, e.g. as a result of chemical influences or high temperatures. |
