Abstract
The application is generally directed towards an airfoil for a fluid delivery tube. The airfoil includes a securing member operably connecting the airfoil to the tube, a fin extending downward and outward from the securing member and terminating in a tip, a shield extending inward and downward from the tip of the fin, and an air guide extending from a first end of the shield.
Claims13
An airfoil for use with a drop nozzle, comprising:
- a bracket configured to be connected to the drop nozzle;
- a fin extending outward and angled downward from the bracket;
- and
- a shield connected to the fin and arranged substantially perpendicularly to the fin to define a surface intersecting with a bottom edge of the fin,
- wherein airflow is directed along the fin to the surface of the shield and toward the drop nozzle.
2 more elements
A method of using an airfoil with a fluid delivery tube, comprising:
- coupling the airfoil to the fluid delivery tube using a bracket of the airfoil, the airfoil further comprising a fin extending from the bracket, and a shield connected to the fin and arranged substantially perpendicularly to the fin to define a surface intersecting with a bottom edge of the fin, wherein the fluid delivery tube is coupled to a nozzle and the bracket is positioned above the nozzle;
- and
- causing the fluid delivery tube to move, wherein during movement, the fin directs airflow to the surface of the shield and toward the nozzle.
