Description
When the temperature of the medium surrounding bellows 1 drops, the volume of the liquid with which the bellows is filled changes, deforming the bellows and moving piston 2. Valve spool 3, rigidly linked to piston 2, shifts downward. The fluid delivered by the pump to the valve is directed to the power cylinder controlling the radiator flaps. This raises the temperature of the medium. When the temperature increases, the elements of the thermostat operate in the reverse direction. The body of the valve can be adjusted along the axis of the thermostat housing by changing the length of regulating tie-rod 4. This controls the motion of the flaps and the temperature of the coolant.
