Patent ID: 8474419

Claim:
A temperature control valve 10 for regulating a flow of coolant 15 in an automotive cooling system 11 that includes an engine 12 and a radiator 14 , the temperature control valve 10 comprising: a valve body 40 having an inlet 42 and an outlet 46 ; a first valve assembly 100 that is moveable between a closed position, wherein the inlet 42 is not in fluid communication with the outlet 46 , and an open position, wherein the inlet 42 is in fluid communication with the outlet 46 ; a chamber 74 adjacent to the first valve assembly 100 , wherein a fluid pressure within the chamber 74 moves the first valve assembly 100 between the open position and the closed position; a second valve assembly 130 configured to regulate the fluid pressure within the chamber 74 to thereby move the first valve assembly 100 between the open position and the closed position; and a fuel type sensor 26 to detect the type of fuel used by the engine 12 and provide a fuel type signal, wherein the second valve assembly 130 regulates the fluid pressure within the chamber 74 based at least in part on the fuel type signal.
