ABSTRACT:
A bleed valve for a compressor wherein compressor discharge pressure is proportional to compressor rotor speed, the bleed valve including a bleed control poppet valve, a pair of differential pressure diaphragms, a pressure regulator valve, and an accumulator. The bleed valve automatically effects bleed air flow in proportion to the rate of acceleration of the compressor rotor when the rate of compressor rotor acceleration exceeds a scheduled maximum rate and for a predetermined duration after the onset of compressor rotor deceleration at a rate above a minimum scheduled rate.
