LIQUID SYSTEM SERVICEABILITY PRESERVATION METHOD Russian patent published in 2003 - IPC

FIELD: preservation of serviceability at long storage. SUBSTANCE: according to proposed method, system is filled with working liquid and is connected with compensating chamber with working liquid and with gas space separated from liquid by deformable tight surface. In case of operation of system without its switching on, gas space is placed in communication with atmosphere, and before switching on the system or in period of reduction of barometric pressure by preset value, shutoff-bypass device is used to interrupt communication of gas space with atmosphere or communication of compensating chamber with system. EFFECT: improved reliability. 2 cl
