ABSTRACT:
The present invention is directed to bleed air systems which derive air from a compressor. In one embodiment of the present invention, a compressor including three bleed ports is connected in a predetermined manner to a bleed air output connector through three controllable shutoff valves and two check valves. More particularly, the bleed air port connected to the highest pressure compressor stage is connected to the output connector through all three of the shutoff valves. The bleed air port connected to the second highest pressure compressor stage is connected to the output connector through one of the check valves and the second and third shutoff valves. Finally, the bleed air port connected to the lowest pressure compressor stage is connected to the output connector through the second check valve and the third shutoff valve.
