Abstract
L'invention concerne les installations de pompage à débit variable. Elle se rapporte à une installation de pompage dans laquelle des distributeurs 131 à 135 assurent le fonctionnement avec un couple constant, et réduisent automatiquement le volume déplacé par la pompe lorsque la viscosité du fluide dépasse une valeur prédéterminée et lorsque la pression dans l'installation dépasse une valeur prédéterminée. Application aux installations de pompage protégées contre les surcharges.
