TEMPERATURE CONTROLLER Russian patent published in 1999 - IPC

FIELD: measurement technology. SUBSTANCE: invention refers to direct action temperature controllers. Given temperature controller has case with supply and discharge conduits, thermal cylinder with piston and shut-off element. Novelty of temperature controller lies in mounting of power cylinder with piston outside case of controller which pressure space communicates with pressure space of thermal cylinder coupled to shut-off element. Rod of power cylinder has mechanism for its extension, for instance, of screw type. Absorbing member, for example, bellows can be placed between shut-off element and rod of thermal cylinder. Such design of temperature controller increases convenience of its adjustment and its operational reliability. EFFECT: increased convenience of adjustment and operational reliability of temperature controller. 2 cl, 2 dwg
