ABSTRACT:
A flow controllable spray nozzle comprising a barrel with a pair of symmetrical, helically-inclined slots on the outside surface and a partition plate with a hole formed therethrough disposed inside the barrel, an internally-threaded control ring with an inside diameter greater than the inside diameter of a housing integrated thereunder, depending therefrom, and a plunger secured inside the housing with a threaded nozzle cup screwed on the control ring to define a space therebetween complemental in size and shape to the upper portion of the barrel so as to receive the barrel therein. Each of a pair of symmetrical, threaded holes formed through the housing receives, in order, a cup, a coil spring and a screw with a post projecting therefrom. The cup, being pushed by the reaction force of the spring, is received by and firmly contacts with one of the slots to guide the plunger moving along the slot. A cone is disposed under the plunger. When the plunger is in the lowest position, the cone is in close contact with a gasket disposed around the hole in the partition plate closing the hole. When the plunger is moved upward, the cone loses contact with the gasket and opens the hole, discharging fluid.
