The invention relates to a stator for an eccentric screw pump or an eccentric worm motor having a stator, including an outer tube that is provided with a lining of rubber or a rubber-like material and has a hollow space, in the shape of a double or multiple spiral, for accommodating a rigid rotor that is also in the form of a spiral, whereby the spiral of the stator has one spiral more than does the motor. To provide a stator that also remains functional under conditions where the fixed connection between the lining and the outer tube would be destroyed, e.g. due to chemical influences or high temperatures, the invention proposes that an inner tube provided with apertures is disposed in the lining, and that spacing strips are disposed between outer tube and inner tube.
Stator pour pompe à vis excentrée ou pour moteur à vis sans fin excentrée doté d'un stator, comprenant un tube extérieur doté d'un revêtement en caoutchouc ou fait d'un matériau caoutchouteux et qui comporte un espace creux, en forme de spirale double ou multiple, dans lequel se loge un rotor rigide qui est aussi en forme de spirale. La spirale du stator comporte une spire de plus que le moteur. Pour que le stator demeure fonctionnel même si la connexion fixe entre le revêtement et le tube extérieur est brisée, par exemple sous l'influence de produits chimiques ou de températures élevées, un tube intérieur doté d'ouvertures est placé dans le revêtement et des bandes d'espacement sont placées entre le tube extérieur et le tube intérieur.
