DIRECT OPERATING CONTROLLER FOR THERMAL CONTROL SYSTEMS Russian patent published in 2000 - IPC

FIELD: maintenance of constant temperature. SUBSTANCE: invention can be recommended for maintenance of constant temperature in compartments of spacecraft. Direct operating controller for thermal control systems has body with two feeding and one discharging pipe unions, thermal compensator with output shaft, return spring, rod with two face surfaces and guide, bushing with axial hole mounted for movement inside body along axis of thermal compensator. Guide of rod is installed in hole of bushing uniaxially to thermal compensator. Output shaft of thermal compensator contacts rod and opposite end of thermal compensator is coupled to body via set of adjustment washers. One of feeding pipe unions is connected by conduits to face surface of rod facing thermal compensator and the other feeding pipe union is connected by conduits to face surface of bushing facing face surface of rod opposite to thermal compensator. Insertion of adjustment elements into structure of controller provides for adjustment of temperature conditions in discharging line without change of flow rate in feeding lines and decreases range of temperature variation in them. EFFECT: simplified design of controller, provision for adjustment of flow rate of liquid in feeding lines and decreased range of temperature variation in them. 1 dwg
