Patent ID: 7712317

Claim:
A flow control system comprising: a fluidic control device having a main fluid path for a main flow of fluid through the device, and a control fluid path for a control flow of fluid through the device, wherein at least part of the control fluid path coincides with at least part of the main fluid path to control a flow of fluid out of the fluidic control device, and the main fluid path of the fluidic control device is arranged in fluid communication with a relatively low pressure compressor stage of a gas turbine engine and the control fluid path is arranged in fluid communication with a relative high pressure stage or a turbine of the gas turbine engine; and a valve associated with the control fluid path, the valve being movable between an open condition to allow fluid to flow along the control fluid path to effect the aforesaid control of the fluid flow out of the fluidic control device, and a closed condition to inhibit or prevent fluid flow along the control fluid path.
