Abstract:
A fluid bypass valve includes a valve member disposed within a valve chamber of a housing. A temperature based actuating mechanism moves the valve member between a first position and a second position in response to a temperature change. A temporary flow control device undergoes a one-time only shape change between a first shape and a second shape. The temporary flow control device enables fluid communication between a first port and a second port when exhibiting the first shape, and does not enable fluid communication between the first port and the second port when exhibiting the second shape. The temporary flow control device exhibits the first shape when having an initial temperature less than or equal to a second pre-defined temperature, and exhibits the second shape in response to a first heating of the temporary flow control device to a temperature that is greater than the second pre-defined temperature.
