Abstract: A valve is provided and includes a bypass block defining a bypass flowpath fluidly communicable with main flowpaths, a member disposable within the bypass block to occupy and move between first and second positions, the member being configured to permit fluid flow through the bypass flowpath when occupying the first position and to block a portion of the bypass flowpath to thereby prevent fluid flow through the bypass flowpath when occupying the second position and an elastic element. The elastic element is coupled to the member and configured to bias the member in a biasing direction toward the second position responsive to a temperature of fluid flowing along the main flowpaths.
