1. A fluid routing device for directing the transportation of a fluid, said fluid routing device comprising:

  • a housing defining an interior and further defining a first corridor and a second corridor selectively fluidly coupled to one another;

    a valve assembly disposed in said interior and capable of alternating between an open configuration and a closed configuration with said valve assembly fluidly coupling said first and second corridors to one another when in said open configuration and said valve assembly fluidly separating said first and second corridors from one another when in said closed configuration;

    a shape memory alloy member mounted to said housing within said interior and extending toward said valve assembly, said shape memory alloy member alternating between a first length in a de-energized state and a second length in an energized state; and

    a link disposed within said interior and pivotably mounted to said housing with said link coupled between said valve assembly and said shape memory alloy member, said link pivoting relative to said housing between a first position when said shape memory alloy member is in said de-energized state and said first length and a second position when said shape memory alloy member is in said energized state and said second length, said link configured to alternate said valve assembly between said closed configuration when said link is in said first position and said open configuration when said link is in said second position for selectively fluidly coupling said first and second corridors to one another;

    wherein said valve assembly includes a diaphragm to fluidly separate said interior of said housing and said first and second corridors;

    wherein said valve assembly includes an actuator movable between an open position when said valve assembly is in said open configuration and a closed position when said valve assembly is in said closed configuration; and

    wherein said valve assembly includes a bias member abutting each of said housing and said actuator with said bias member biasing said actuator into said closed position.
