ABSTRACT:
An air distribution valve for use in a passageway of an environmental control system. The air distribution valve comprises a valve body including an input and multiple outputs defining a volume. The valve body is adapted for placement in the passageway for receiving the air in the input. A valve member is used for selectively distributing the air between the multiple outputs. Damping devices for damping the unstabilizing effect of the air flow on the valve member as the air flows to the multiple outlets allow, allowing for the lowest pressure drop configuration. An environmental control system designed for use with a vehicle includes an air cycle machine for conditioning air, ducting for distributing the air within the vehicle for a plurality of uses, and an air distribution valve for use in the ducting. The air distribution valve comprises a valve body including an input and multiple outputs defining a volume. The valve body is adapted for placement in the passageway for receiving the air in the input. A valve member is used for selectively distributing the air between the multiple outputs. Damping devices for damping the unstabilizing effect of the air on the valve member as the air flows to the multiple outlets is also provided.
