Temperature actuated multiple function fluid control valve

DETAILED DESCRIPTION The present temperature responsive fluid flow control valve regulates two fluid flow systems and hence the two functions, in positive sequential fashion, using the same temperature sensor.
The control is particularly suitable for controlling an automatic radiator shutter and an air operated fan drive clutch of an engine in cooperative fashion.
Only one port in the engine block is necessary.
The same valve unit sequentially controls the fluid supply to both the shutter and the fluid supply to the clutch.
The two functions cannot overlap and interfere with each other.
Rather, their cooperative function assures a wide range of regulated air flow conditions to optimize engine operating temperature for better fuel economy and longer engine life.
