Abstract
A nozzle assembly for use with an agricultural crop sprayer includes a nozzle body and a turbine element journaled to the body. The turbine element has a fluid-conveying internal passage having a rifled profile. Other nozzle assemblies have a nozzle tip journaled to a nozzle body, and the nozzle tip has a fluid-carrying passage with a surface profile configured to interact with fluid passing therethrough to apply a torque on the nozzle tip.
Claims14
A nozzle assembly for use with an agricultural crop sprayer, the nozzle assembly comprising:
- a nozzle body;
- a bearing secured inside the nozzle body, wherein the nozzle body and bearing together define a circular aperture;
- and
- a turbine element journaled inside the bearing, the turbine element defining a shoulder having a diameter greater than a diameter of the aperture, the turbine element defining an internal passage configured to convey a fluid, the internal passage having a rifled profile, wherein the turbine element comprises a nozzle tip having a nozzle opening formed in an end face of the nozzle tip, the nozzle opening being in fluid communication with the internal passage;
- wherein the turbine element defines at least one radially offset channel extending through the shoulder outward from the internal passage.
A nozzle assembly for use with an agricultural crop sprayer, the nozzle assembly comprising:
- a nozzle body;
- a bearing secured inside the nozzle body and defining a circular aperture;
- a turbine element journaled inside the bearing, the turbine element defining an internal passage configured to convey a fluid, the internal passage having a rifled profile, the turbine element comprising lugs on a circumferential face;
- and
- a nozzle tip coupled to the turbine element, wherein the nozzle tip is in fluid communication with the internal passage;
- wherein the lugs are configured for keying with the nozzle tip.
A nozzle assembly for use with an agricultural crop sprayer, the nozzle assembly comprising:
- a nozzle body;
- a bearing secured inside the nozzle body and defining a circular aperture;
- and
- a nozzle tip journaled inside the bearing, the nozzle tip having a nozzle opening formed in an end face of the nozzle tip, the nozzle tip defining a fluid-conveying passage having a surface profile configured to interact with a fluid passing through the passage to apply a torque upon the nozzle tip, wherein the surface profile defines a plurality of radially offset vanes extending outward from the nozzle opening.
