Patent ID: 7093617

Claim:
A flow control device for use with a hot gas generator having a pressure vessel and providing a combustion gas output, the flow control device comprising: a fluidic amplifier having a fluid inlet port and at least two fluid outlet ports, the fluid inlet adapted to receive hot pressurized fluid from the gas generator pressure vessel; and a fluidic diverter valve including: a housing having a first fluid inlet port, a second fluid inlet port, a first fluid outlet port, a second fluid outlet port, and a shuttle element cavity formed therein, the first fluid inlet port coupling a first one of the fluidic amplifier fluid outlets in fluid communication with the shuttle element cavity, the second fluid inlet port coupling a second one of the fluidic amplifier fluid outlets in fluid communication with the shuttle element cavity, the first and second fluid outlet ports each in fluid communication with the shuttle element cavity, and a non-spherical shuttle element freely disposed within the shuttle element cavity, the shuttle element including a main body having substantially flat first and second sides disposed substantially parallel to one another, and a substantially symmetrically shaped peripheral section located between the first and second sides, the shuttle element translationally moveable in response to hot pressurized fluid flow through the inlet ports to move between at least a first position and a second position, wherein at least a portion of the shuttle element first side substantially seals the first fluid outlet port in the first position, and at least a portion of the shuttle element second side substantially seals the second fluid outlet port in the second position.
