  • a first port, a second port, and a third port;

    a valve;

    a clutch that is provided with an engaged position and a disengaged position, wherein at least a portion of the clutch may move relative to the valve when the clutch is in the disengaged position and wherein the clutch moves the valve when the clutch is in the engaged position;

    the valve being movable between a first position, a second position, and a third position, whereby;

    when the valve is in the first position, the valve blocks a first pathway, which extends from the first port, from connecting with a second pathway, which extends from the second port;

    when the valve is in the second position, the valve allows the first pathway to connect with the second pathway; and
