Abstract
A spray device for use as an alternate water discharge to a faucet has a body with a handle and a spray head. The spray head has discharge openings therein. There is a trigger movable on the body between an off position and an on position. There is a chamber within the body which is in communication with a source of water under pressure and there is a water passage between the chamber and the discharge openings. A valve is movable within the chamber in response to movement of the trigger to connect the source of water under pressure through the chamber, to the water passage, and then to the discharge openings. The water passage is formed between closely spaced facing walls having a textured surface thereon to create adequate surface tension with water within the water passage, whereby water therein will not move to the discharge openings unless the water passage is connected to the source of water under pressure.
