Abstract
The invention is a substantially cylindrical nozzle for a spray apparatus designed to emit accurate fluid spray of uniform sized droplets. The fluid to be sprayed is urged under pressure into an inner-bore cylindrical reservoir channel, in communication with a fluid pressure responsive, positive action valve plunger. Positive displacement of the valve plunger enables the fluid to pass under the influence of fluid pressure through openings in a detachably secured connector and to exit the nozzle through substantially axially disposed, flared outlet tubes. Uniform droplet size and spray coverage is promoted by the streamlined shape of the nozzle body, flare of the outlet tubes, and dimensions (length and small internal diameter) of the outlet tubes.
