Abstract

A trigger sprayer is described which utilizes a ball valve to control the flow of a carrier fluid such as water. The ball valve is actuated by a trigger which is biases to the open position by a torsion spring. Provision is made for the trigger sprayer to draw a chemical solution from a supply container and meter it through one or more outlet devices for providing streams in the form of fan or mist sprays, or other shaped sprays.

Claims

1. A hose-end sprayer, comprising:

a carrier fluid inlet connection;

a carrier fluid flow control valve downstream of the carrier fluid inlet connection;

a lever that rotates the carrier fluid flow control valve, the lever and carrier fluid flow control valve being biased into a closed position by a spring; and

an outlet turret downstream of the carrier fluid flow control valve.

2. The hose-end sprayer of claim 1, wherein the carrier fluid flow control valve comprises a spherical shape over at least a portion of its surface.

3. The hose-end sprayer of claim 1, wherein the lever and the spring are molded as a single piece.

4. The hose-end sprayer of claim 1, wherein the carrier fluid follows a flow path that is generally linear along a first axis.

5. The hose-end sprayer of claim 4, wherein the carrier fluid flow control valve rotates about a second axis that is generally perpendicular to the first axis.

6. The hose-end sprayer of claim 4, wherein the outlet turret rotates about the first axis.

7. The hose-end sprayer of claim 4, wherein the outlet turret rotates about a third axis that is parallel to the first axis.

8. The hose-end sprayer of claim 4, wherein the outlet turret comprises a first flow passage that is parallel to the first axis.

9. The hose-end sprayer of claim 8, wherein the outlet turret comprises a second flow passage that is parallel to the first axis.

10. The hose-end sprayer of claim 9, wherein the first flow passage and the second flow passage provide different outlet spray patterns.

11. The hose-end sprayer of claim 8, wherein the turret further comprises a chemical connection perpendicular to the first axis and connected between the first passage and a chemical source.

12. The hose-end sprayer of claim 8, wherein the outlet turret has a position in which the first flow passage is connected to the carrier fluid flow control valve.

13. The hose-end sprayer of claim 9, wherein the outlet turret has a position in which the second flow passage is connected to the carrier fluid flow control valve.

14. The hose-end sprayer of claim 8, wherein the outlet turret has a position in which the first flow passage is not connected to the carrier fluid flow control valve.

15. The hose-end sprayer of claim 11, further comprising a metering orifice between the first passage and the chemical source.

16. The hose-end sprayer of claim 1, further comprising a closure for attaching to a chemical supply container.

17. The hose-end sprayer of claim 1, wherein the lever pivots upon at least one axle, and the axle is attached to the carrier fluid flow control valve.
