1. A diverter valve for use in a system comprising a ram air system including a ram inlet and a ram outlet and a ram fan that draws air from the ram inlet to the ram outlet, a cabin air compressor motor including a motor cooling inlet passage and a motor cooling outlet passage, said motor inlet cooling passage being coupled to said ram inlet and a dedicated exhaust separate from the ram outlet, the valve comprising:
a valve body including a first diverter inlet, a first diverter outlet and a second diverter outlet;
wherein the first diverter inlet is configured for connection to the motor cooling outlet passage, the first diverter outlet is along a first axis configured for connection to the dedicated exhaust and the second diverter outlet aligned along a second axis that is orthogonal to said first axis and is configured for connection to the ram outlet;
a rotary actuator mechanically connected to said valve body; and
a flapper pivotally mounted within said valve body such that said flapper is movable by said rotary actuator in response to a flight mode of operation or a ground mode of operation;
wherein in the flight mode of operation the rotary actuator causes the flapper to cause air entering the first diverter inlet to exit the diverter valve through the first diverter outlet into the dedicated exhaust separate from the ram outlet; and wherein in the ground mode of operation the rotary actuator causes the flapper to cause air entering the first diverter inlet to exit the diverter valve through the second diverter outlet into the ram outlet.
