description	A fuel nozzle for a combustor may include a primary fuel passage having a primary fuel outlet. The secondary fuel passage has a secondary fuel outlet. A valve is located within the secondary fuel passage. The valve may include a fixed hub having a plurality of first sloped surfaces. The valve may include a movable sleeve having a plurality of second inclined surfaces. Each of the plurality of first sloped surfaces is axially aligned with a respective one of the plurality of second sloped surfaces to define a slot therebetween. The valve is movable between a plurality of positions to open, close, or partially open the slot. 一种用于燃烧器的燃料喷嘴可包括具有初级燃料出口的初级燃料通道。次级燃料通道具有次级燃料出口。阀位于次级燃料通道内。该阀可以包括具有多个第一倾斜表面的固定毂。该阀可以包括具有多个第二倾斜表面的可移动的套筒。多个第一倾斜表面中的每一个与多个第二倾斜表面中相应的一个轴向对齐，以在其间限定槽。阀能够在多个位置之间移动，以打开、关闭或部分打开槽。
