METHOD FOR PROVIDING PREDETERMINED TEMPERATURE CHARACTERISTICS OF CONTROLLING MEMBERS WORKING IN DEPENDANCE UPON TEMPERATURE AND CONTROLLING MEMBER WORKING IN DEPENDANCE UPON TEMPERATURE Russian patent published in 1999 - IPC

FIELD: provision of predetermined temperature characteristics of controlling members of valves and thermostats working in dependance upon temperature. SUBSTANCE: controlling members may operate according to pressure value in pressure chamber filled with gas-liquid mixture. In order to provide desirable temperature characteristics, mixture of toxic and ecologically hazard matters is sometimes used. Method comprises use of non-azeotropic mixture including at least two nontoxic and ecologically safe components for filling pressure chamber with relation of components selected according to desired characteristics. EFFECT: enhanced safety of method due to use of nontoxic and ecologically safe components of mixture in pressure chamber. 17 cl, 5 dwg
