Abstract

Un bâti (1) comportant au moins une entrée raccordée à une conduite d'amenée de liquide (CA) créant une chute motrice, une sortie de refoulement munie d'une soupape de refoulement (15) et une sortie d'échappement munie d'une soupape d'arrêt (14), et une chambre à air (2) communiquant avec une conduite de refoulement (CR) raccordée dans la partie inférieure de la chambre à air, celle-ci comprenant une paroi étanche souple (20) formant une enceinte intérieure hermétique pour un gaz sous pression. A frame (1) comprising at least one inlet connected to a liquid supply line (CA) creating a fall drive, a discharge outlet fitted with a valve discharge (15) and an exhaust outlet provided a shut-off valve (14), and an air chamber (2) communicating with a discharge line (CR) connected in the lower part of the chamber air, the latter comprising a flexible waterproof wall (20) forming an airtight interior enclosure for a gas under pressure.
