Abstract
A spray nozzle has a nozzle portion at an outlet or downstream end that includes a nozzle body defining an opening therethrough, and a movable stem or pintle at least partially within the opening of the nozzle body. The stem and nozzle body define a gap therebetween to define a fluid passageway for fluid in the nozzle to flow through the nozzle portion and out of the nozzle throughout a range of relative movement between the stem and the nozzle body. The relative movement and the size of the gap may be controllable independently of fluid pressure of fluid within the nozzle. The nozzle body and the stem may define geometries so that the flow area between the stem and the nozzle body does not increase, and may decrease, in the downstream direction. The axis of the spray may be at an angle to the nozzle.
