Flow pulsing valve and fuel supply system for a turbine engine incorporating same

摘要

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.
