Patent ID: 8899494

Claim:
A fuel nozzle, comprising: a fuel passage through which a fuel flows; an air passage through which air flows; and a wall separating the fuel passage from the air passage, wherein the wall comprises: at least one fuel injection port extending from a first side of the wall to a second side of the wall for injecting the flow of fuel into the flow of air; and first and second feedback lines extending from a downstream end of the fuel injection port to an upstream end of the fuel injection port, wherein the first and second feedback lines are disposed on opposite sides of the fuel injection port, and wherein the first and second feedback lines are disposed entirely within the wall, wherein the first and second feedback lines are configured to passively induce feedback flows of fuel through the first and second feedback lines in an alternating manner such that the flow of fuel through the fuel injection port oscillates from side to side of the fuel injection port.
