Nozzle body apparatus
Embodiments of the invention provide a nozzle body including a main body, a turret, a valve assembly, and a feed spigot. The feed spigot can be in fluid communication with a valve chamber via a first feed point and a second feed point. The use of multiple feed points between the feed spigot and the valve chamber can result in increased flow capacity.
1. A nozzle body comprising:
a main body;
a turret;
a valve assembly including a valve chamber; and
a feed spigot in fluid communication with the valve chamber, the feed spigot including a first feed point and a second feed point separated from the first feed point, the first feed point in direct fluid communication with the valve chamber, the second feed point in direct fluid communication with the valve chamber in order to increase flow capacity.
2. The nozzle body of claim 1 wherein the first feed point is an upper feed point and the second feed point is a lower feed point.
3. The nozzle body of claim 1 wherein the first feed point communicates with a top side of the valve chamber and the second feed point communicates with a bottom side of the valve chamber.
4. The nozzle body of claim 1 wherein the main body and the feed spigot are a single molded piece.
5. The nozzle body of claim 1 wherein the main body includes a counterbore.
6. The nozzle body of claim 5 wherein the counterbore is capped by a plug.
7. The nozzle body of claim 6 wherein the plug is sealed by an o-ring and retained with a dowel pin.
8. The nozzle body of claim 1 wherein the turret is a multi-indexable turret.
9. The nozzle body of claim 1 wherein the valve assembly is a diaphragm check valve assembly.
10. The nozzle body of claim 1 wherein the turret includes at least three ports to receive at least three nozzles.
11. The nozzle body of claim 1 wherein at least one of the first feed point and the second feed point is substantially horizontally aligned with the feed chamber.
12. The nozzle body of claim 1 wherein the nozzle body is adapted to attach to a boom of an agricultural crop spraying machine in order to distribute agro-chemical spray.
