Abstract
A temperature control valve 10 for regulating the flow of coolant 15 in an automotive cooling system 11 that includes an engine 12 and a radiator 14. The temperature control valve 10 includes a valve body 40 having an inlet 42 and an outlet 46, a first valve assembly 100 that is movable between a closed position and an open position, and a chamber 74 that is adjacent to the first valve assembly 100. In the closed position of the first valve assembly 100, the inlet 42 of the valve body 100 is not in fluid communication with the outlet 46 of the valve body 100. In the open position of the first valve assembly 100, the inlet 42 of the first valve assembly 100 is in fluid communication with the outlet 46 of the first valve assembly 100. Fluid pressure within the chamber 74 is operable to move the first valve assembly 100 between the open position and the closed position. The temperature control valve 10 may include a second valve assembly 130 that is configured to regulate fluid pressure within the chamber 74 to thereby move the first valve assembly 100 between the open position and the closed position.
