FIELD: pneumohydraulic devices.
SUBSTANCE: hydraulic accumulator comprises housing 1 with a medium separator, made in the form of a piston or elastic membrane 4 and forming a pneumatic and hydraulic cavity, the first of which is equipped with a compressed gas supply valve 2, and the second is equipped with nozzle 3 for connection to a hydraulic line. Along the perimeter of the pneumatic cavity there installed are replaceable pyrocartridges-gas generators 7 and pressure sensor 5 connected to electronic system 6 for controlling ignition of pyrocartridges-gas generators 7.
EFFECT: technical result consists in stabilization of working fluid pressure.
