Nozzle for a pressure washer
View Patent ↗A nozzle for use with a sprayer, such as a spray gun for a pressure washer or a garden hose system, includes a body, which has an inlet for receiving a pressurized flow of water. The nozzle further includes first and second outlets, and first and second passages. The first and second outlets are formed in an end of the body. The first passage extends between the inlet and the first outlet, and the second passage extends between the inlet and the second outlet. The first and second passages are substantially straight and parallel to one another. During operation of the nozzle, the pressurized flow of water from the inlet is split, passes through the first and second passages, and exits the body from the first and second outlets.
1. A spray gun, comprising:
a handle having a trigger for selectively allowing a pressurized flow of water to pass through at least a portion of the spray gun;
a port for receiving a reservoir of chemicals to be selectively added to the pressurized flow of water;
a nozzle body coupled to the spray gun, the nozzle body comprising:
a first inlet for receiving the pressurized flow of water;
a first outlet formed in an end of the nozzle body;
a second outlet formed in the end of the nozzle body;
a first passage extending between the first inlet and the first outlet;
a second passage extending between the first inlet and the second outlet;
a second inlet for receiving a flow of chemicals from the reservoir of chemicals;
a third outlet formed in the end of the nozzle body; and
a third passage extending between the second inlet and the third outlet,
wherein the pressurized flow of water from the first inlet is split, passes through the first and second passages, and exits the nozzle body from the first and second outlets during operation of the spray gun; and
wherein the second inlet, the third passage, and the third outlet are configured to allow the flow of chemicals to exit the nozzle body contemporaneously with the flow of water from the first and second outlets during operation of the spray gun.
2. The spray gun of claim 1 , wherein the first and second passages extend longitudinally through the nozzle body a distance greater than about a quarter of the length of the nozzle body.
3. The spray gun of claim 2 , wherein the first and second passages extend longitudinally through the nozzle body a distance about half the length of the nozzle body.
4. The spray gun of claim 1 , wherein the first and second passages extend longitudinally through the nozzle body a distance of at least a quarter inch.
5. The spray gun of claim 4 , wherein the first and second outlets are arranged symmetrically about an axis of the end of the nozzle body.
6. The spray gun of claim 1 , wherein the third outlet is positioned between the first and second outlets.
7. The spray gun of claim 6 , wherein the third outlet is positioned in the center of the end of the nozzle body.
8. The spray gun of claim 7 , wherein the first and second outlets are substantially equidistant from the third outlet.
9. The spray gun of claim 1 , wherein the first and second passages are each substantially straight.
10. The spray gun of claim 9 , wherein the first and second passages are substantially parallel.
11. The spray gun of claim 10 , wherein the third passage is formed from two substantially straight portions that intersect.
12. The spray gun of claim 11 , wherein one of the two portions of the third passage is substantially parallel with the first and second passages.
13. The spray gun of claim 1 , wherein the first inlet and the second inlet are on separate sides of the nozzle body.
14. The spray gun of claim 1 , further comprising:
a pump coupled to the second inlet for pumping the flow of chemicals from the reservoir to the second inlet.
