FIELD: physics; acoustics.
SUBSTANCE: closed-loop gas compensator with automatic back-pressure retention in deep-sea acoustic devices, e.g. in transducers, comprises a compensated cavity, gas-filled vessels under different pressure with hydrostatic pressure sensors. Compensated cavity by means of pressure-tight baffles is divided into separate chambers piped to different vessels. The chamber connected to the higher-pressure vessel is located inside the chamber connected to the lower-pressure vessel.
EFFECT: simplified design of enhanced robustness, with basic acoustic parameters not affected.
