Abstract
A pulsing valve assembly pulses metered fuel flow to a turbine engine. The pulsing valve assembly comprises a valve housing having an inlet and an outlet. A divider valve divides metered fuel flow into a first flow portion and a second flow portion. A first actuator sets a magnitude of a flow divide between the first and second flow portions. The valve assembly also includes a pulsing valve for pulsing the first flow portion and a second actuator for setting a frequency of pulsing valve. The pulsed and unpulsed flow portions are then joined and delivered to the turbine engine combustion chamber.
Claims26
A valve assembly for pulsing fluid flow, comprising:
- a valve housing having an inlet, an outlet, a first flow path, and a second flow path, the first and second flow paths fluidically between the inlet and the outlet;
- a divider valve arranged to divide fluid flow from the inlet port among the first and second flow paths;
- and
- a pulsing valve along the first flow path downstream of the divider valve, the pulsing valve being movable to successively interrupt flow through the first flow path and thereby pulse fluid flow along the first flow path.
A valve assembly for pulsing a metered fuel flow for a turbine engine, comprising:
- a valve housing having an inlet adapted to receive the metered flow;
- means for dividing the metered flow into a first flow portion and a second flow portion;
- a first actuator setting a magnitude of a divide between the first and second flow portions;
- means for pulsing the first flow portion;
- a second actuator setting a frequency of the pulsing means;
- passageway means for combining the first and second flow portions for communication to the turbine engine, wherein at least one of the first actuator and the second actuator is electrically controllable.
