Abstract
A temperature responsive time delay valve in which free flow of fluid is afforded above a predetermined temperature level and in which a delayed fluid flow is achieved in one direction and free fluid flow in the opposite direction below the predetermined temperature level. The temperature responsive valve portion incorporates a bimetal disc which is supported at its outer periphery by O-rings to provide a resilient mounting and a fluid seal requiring passage of fluid through a central aperture in the disc.
