FIELD: control over valve in heat supply systems. SUBSTANCE: gear for control over actuating mechanisms comprise body housing heating element which is thermocompressor, thermocylinder with working medium which is either completely installed in body of gear or is partially brought outside of its limits. Technical result of invention lies in simplified design and small dimensions of gear in combination with potential for creation of alternating (reciprocating) motions of actuating mechanisms, with potential for controlled heating or cooling to working temperature in temperature interval from -60 to +60 C. EFFECT: simplified design and small dimensions of gear. 1 dwg |
