Abstract: A valve system includes a spin chamber having an outlet drain configured to allow flow out of the spin chamber. A main spin surface of the spin chamber is defined around the outlet drain. A directional jet system is in fluid communication with the spin chamber. The directional jet system includes a member that is configured to move between a first position for directing a tangential flow around the drain, and a second position for directing a radial flow toward the drain.

Abstract: A fuel injector assembly can include a manifold defining a manifold channel and a nozzle extending from the manifold. The nozzle can be configured to direct flow from the manifold channel into a combustor. The nozzle can define a fuel inlet open to the manifold channel, a fuel outlet configured to be open to a combustor, and a throat fluidly connecting the fuel inlet to the fuel outlet. The assembly can include a trim device inserted into the manifold. The trim device can be configured to adjust flow between the manifold channel and the fuel inlet to adjust flow through the throat and out of the fuel outlet.
