    摘要: A starter air valve assembly includes a valve body, a flow control valve, a rate control servo mechanism, and a valve actuator. The valve body defines a flow passage having at least an inlet port and an outlet port. The valve is disposed at least partially within the flow passage and is moveable between an open position and a closed position. The rate control servo mechanism is adapted to receive pressurized fluid and is configured, upon receipt thereof, to supply a controlled flow of the pressurized fluid. The valve actuator is coupled to the valve and is in fluid communication with the rate control servo to thereby receive the controlled flow of the pressurized fluid. The valve actuator is configured, upon receipt of the controlled flow of the pressurized fluid, to move the valve between the closed position and the open position at a substantially controlled rate.

    摘要: A pressure and flow altitude compensated shut off valve includes a valve body, a valve element, and an altitude compensation pilot valve. The valve body has an inlet port, an outlet port, and a flow passage extending between the inlet port and the outlet port. The valve element is disposed within the flow passage and is responsive to fluid pressure at the inlet port to move between a closed position, in which fluid may not flow through the flow passage, and a plurality of open position between the closed position and a full-open position. The altitude compensation pilot valve is coupled to the valve body and is responsive to pressure variations at the second port to control the fluid pressure at which the valve element moves to the closed and open positions.

    摘要: A diaphragm is provided that includes a plurality of zonal portions that define reinforced and non-reinforced areas of the diaphragm. A first zonal portion extends from a marginal edge portion toward a central portion and is formed of a fabric material. A second zonal portion extends from the first zonal portion toward the central portion and is formed of an elastomer. A third zonal portion defines the central portion and is formed of a fabric material. The combination of reinforced and non-reinforced portions provides for a decrease in the radial tension (spring rate) of the diaphragm and helps prevent undesired changes to the flow control valve flow setpoint.
