Abstract

L'invention concerne une pompe rotative. La pompe comporte des moyens pour mesurer ou déceler la pression de fluide en une position de la pompe au niveau de laquelle, en fonctionnement, la pression de fluide varie en fonction du sens de rotation de la pompe. Sur la figure l'orifice 40 communique avec une enceinte formée entre le couvercle et les faces radiales supérieures du segment 14 et des rotors 22 et 24. L'alésage 40 est raccordé à des moyens sensibles à la pression (non représentés) tels qu'une jauge de pression, un commutateur de pression ou un transducteur de pression; grâce auxquels le sens de rotation de la pompe peut être décelé et une action appropriée, telle que l'arrêt de la pompe principale, peut être commandée, soit manuellement, soit automatiquement.
