DEVICE TO COMPENSATE FOR LOSSES OF WORKING MEDIUM FROM HYDRAULIC MAIN LINE OF SEALED MANNED COMPARTMENT THERMAL CONTROL SYSTEM AND METHOD OF ITS OPERATION Russian patent published in 2013 - IPC B64G1/50 G01M3/30 

Abstract RU 2497731 C1

FIELD: transport.

SUBSTANCE: invention relates to manned spacecraft thermal control systems. Proposed device is intended for in-flight top-up of hydraulic line of said thermal control system equipped with working medium hydropneumatic compensator. It includes two-chamber tanks for working medium and air valves to control current volume of compensator gas chamber. Control consists in working medium displacement to thermal control system hydraulic line from said tank by pressure difference between said gas chamber and said line. Note here that gas chamber initial volume is measured at air pressure P1 equal to manned compartment pressure. Said pressure difference is created by supercharging of aforesaid gas chamber to maximum operating pressure in hydraulic line. Working medium displacement into said line is controlled by compensator gas chamber pressure. Displacement of working medium is terminated after said pressure reached magnitude dependent on , P1and design volume AV of working medium top-up amount. Compensator gas chamber volume is re-measured and in case relationship is satisfied control operation is considered fulfilled.

EFFECT: expanded operating performances, multiple use, decreased weight and sizes, higher reliability.
