Abstract:
A temperature activated diversion valve for supplying a first inflow fluid as an outflow fluid and for switching to supply a second inflow fluid as such outflow fluid if such first inflow fluid attains a specified temperature, said temperature activated diversion valve comprising:a first inflow conduit for carrying such first inflow fluid;a second inflow conduit for carrying such second inflow fluid;an outflow conduit;a valve member;said valve member being moveable between a first position and a second position;said valve member establishing fluid communication between said first inflow conduit and said outflow conduit in said first position;said valve member substantially blocking fluid communication between said second inflow conduit and said outflow conduit in said first position;said valve member establishing fluid communication between said second inflow conduit and said outflow conduit in said second position; andsaid valve member substantially blocking fluid communication between said first inflow conduit and said outflow conduit in said second position;a biasing element exerting a biasing force urging said valve member toward said second position; anda bonding element restraining said valve member in said first position against said biasing force exerted by said biasing element;said bonding element being thermosensitive to substantially release said restraining of said valve member in said first position upon said bonding element substantially attaining said specified temperature.
