Abstract
A stationary rinse nozzle made of durable, non-corrosive material includes a simple deflector directing a uniform water jet in all directions so the need for a rotating nozzle or a multi-apertured rinse tube is eliminated. A large rinse orifice provides the necessary volume of water for effective low pressure rinsing of residual products from the tank walls. The deflector support is located in the middle of a tube so that blank spots in the spray pattern are avoided.

Rinse structure for the solution tank of an agricultural sprayer having walls with inside surfaces subject to accumulation of residue from chemicals, the rinse structure comprising:
- a source of pressurized rinse;
- a rinse tube connected to the pressurized rinse and having an outlet providing a high capacity flow rate along an egress path;
- a deflection member supported within the tank between the walls and having a concave portion intercepting the egress path to provide a continuous high volume sheet of rinse fluid for rinsing the accumulation of residue from the walls.
Rinse nozzle structure for the solution tank of an agricultural sprayer having walls with inside surfaces subject to accumulation of residue and a source of pressurized rinse connected to a rinse tube, the rinse nozzle structure comprising:
- a tube having a central bore adapted for connection to the pressurized rinse, the bore defining a generally circular outlet having a diameter providing a high capacity flow rate along an egress path;
- a support member supported within and extending from the bore, the support member located centrally with respect to the bore and having a dimension substantially less than the diameter of the outlet so that flow adjacent the bore exits the outlet substantially undeflected;
- a concave deflection member supported from the support member at a location offset from the outlet and having a continuous portion intercepting the egress path to provide a high volume, non-interrupted sheet of rinse fluid for rinsing the accumulation of residue from the walls.
