Method and devices for keeping the gas contained in a submerged enclosure in balance with the outside pressure

摘要

the invention is directed to a process and devices for maintaining the gas in a chamber disposed in pressure equilibrium with the outside.a device according to the invention includes a water chamber 1, for example, a transducer housing which is connected to the piu00e9zou00adu00e9lectrique pipes 2, 4 to several cylinders 5, 6, 7), each containing a deformable bag, which pockets are pru00e9gonflu00e9es to pressure difference various.the cylinders 6 and 7 contain pockets pru00e9gonflu00e9es at a pressure higher than the atmospheric pressure, and is equipped with a three way valve 12 which isolates the corresponding pocket as the hydrostatic pressure is less than the pressure in the bag.;one application is the maintenance of the electroacoustic transducer equipressure immersed at great depth.
