  • Bleed valve system for a gas turbine engine
    Patent number: 6695578
    Abstract: A bleed valve assembly includes a valve poppet having a bleed portion and a base portion separated by a radially extending flange. The radially extending flange is located about the perimeter of the valve poppet to engage the valve seat on one side and receive a biasing member on the other. The flange engages the valve seat such that initial valve performance is similar to a disk valve, i.e., soft seating and very low leakage when closed. A plurality of openings extend through the bleed portion such that partial open operation of the bleed valve assembly is particularly tailored for a desired flow. As the valve poppet of the present invention moves off the valve seat, the initial gain is very low and then the gain increases steadily as more openings are exposed.
