Abstract

Abstract Translated from French L'invention concerne des pompes volumétriques rotatives où des galets répartis à la périphérie d'un rotor écrasent un ou plusieurs tubes flexibles contre la paroi d'un stator cylindrique concentrique, lesdits tubes étant, en fait, tendus entre deux ancrages pratiquement diamétralement opposés sur le stator qui peut s'écarter du rotor pour les besoins de l'entretien courant, notamment des tubes qui sont rapidement interchangeables. Elle est caractérisée par le fait que l'on prévoit un dispositif permettant d'agir sélectivement sur les tubes tout en les maintenant constamment obturés. Application aux analyses automatiques. The invention relates to rotary positive-displacement pumps in which rollers distributed around the periphery of a rotor crush one or more flexible tubes against the wall of a concentric cylindrical stator, said tubes being, in fact, stretched between two anchors which are practically diametrically opposed on the stator which can move away from the rotor for the needs of the routine maintenance, in particular tubes which are quickly interchangeable. It is characterized by the fact that a device is provided which makes it possible to act selectively on the tubes while keeping them constantly closed. Application to automatic analyzes.
