PASSIVE STABILITY BLEED VALVE WITH ADJUSTABLE REFERENCE PRESSURE REGULATOR AND REMOTE OVERRIDE CAPABILITY

A bleed air valve (100) comprises a housing (102) that includes an inlet (104), an outlet (106), and a center portion (107) to selectively provide a pneumatic flow path between the inlet (104) and the outlet (106). A piston (118) moves along a center guide (112) in response to forces applied to the...

description A bleed air valve (100) comprises a housing (102) that includes an inlet (104), an outlet (106), and a center portion (107) to selectively provide a pneumatic flow path between the inlet (104) and the outlet (106). A piston (118) moves along a center guide (112) in response to forces applied to the piston, where the piston (118) is spring biased to an open position. The valve also comprises a pressure regulator valve (119) that comprises a spring loaded poppet valve that includes a pressure regulator inlet (120) that receives an inlet pressure which is regulated based upon force applied to a pressure regulator piston (122). A valve spring (130) applies a force to the piston first surface to spring bias the bleed air valve (100) to the open position. A solenoid valve (130) receives a command signal and in response provides compressed air to a solenoid valve outlet (136) that is in fluid communication with the pressure regulator inlet.
