ABSTRACT:
A variable flow control valve for multiport injection of pressurized liquid through an array of injection nozzles for a gas turbine engine is connected by nozzle ports to the engine. The valve includes a slidable valve element which progressively opens and closes a plurality of first ports by sliding triangular apertures thereover. A plurality of second ports communicate with a chamber containing the slidable valve element, the second ports also communicating with individual compensators that are in communication with the first ports and nozzle ports. The compensators connect the first ports to the nozzle ports through variable flow valves which are biased to the fully open opposition against the pressure of liquid in the second ports. By so configuring the flow control valves, pressure in the chamber compensates for pressure surges in the pressurized liquid by reducing flow through the variable flow valves in response to pressure increases in the pressurized fluid.
