FIELD: engines and pumps.
SUBSTANCE: suggested device consists of reservoir for working medium with fluid and gas cavities, hermetically separated one from another with movable medium separator. The fluid cavity is filled with working medium of a hydraulic pipeline. The gas cavity is filled with a displacing gas and via a shutoff valve and pneumatic socket of the pipeline is connected to the gas cavity of the hydro pneumatic compensator. A standard capacity, a vacuum pump and a pressure blower are connected to the pneumatic pipeline. According to a suggested method volume of the gas cavity of the working medium reservoir is preliminary measured and then the air pressure is achieved somewhat less than the pressure in a crew compartment. Then the gas cavity of the hydro pneumatic compensator is vacuumized to the value of pressure exceeding the pressure of saturated steams of working medium at a value of absolute error in a pressure sensing port of the hydraulic pipeline. Then working medium of the said reservoir fluid cavity is being displaced into the hydraulic pipeline, at that the constant control of the current pressure in the gas cavity of this reservoir is being carried out. Displacing is terminated when this pressure falls down to a specified value depending on the volume of a refilling dose of working medium, on the volume of the gas cavity of the said reservoir before displacing of the given dose, and on air pressure values in the gas cavity prior to displacing and after it.
EFFECT: prolongation of a life time of thermo regulating systems and of duration of a flight.
