FIELD: machine building; measuring equipment.
SUBSTANCE: invention is a technical solution of physical quantity sensors failure-free operation under conditions of high pressure and gas-dynamic impact. Working system of spacecraft correction with fully generated from high-pressure tank remains of working gas includes high-pressure tank with working gas, main lines, instrumentation and control, actuating working element, pneumo-cylinder made of material with elastic properties, located in tank cavity, temperature sensors protection device, high and low pressure working gas sensors from high-pressure waves in main lines. Initially, in the pre-operation state, inside the unregulated working gas tank there is a pneumatic cylinder shaped as a tank with supercharging gas, the initial pressure of which is not less than working pressure in the actuator of the working system.
EFFECT: technical result is exclusion of unusable working medium residue in tank.
