ABSTRACT:
In a vehicle for spreading liquid material, disclosed is a spray manifold based on an inventive variable orifice nozzle, spraying beyond the vehicle span while not extending beyond the vehicle span. Because of the inventive nozzle the vehicle is able to spray beyond the span of the vehicle with a uniform application to a swath of land over varying vehicle speeds and flow rates. The disclosed nozzle achieves a constant velocity and exit flow trajectory for a wide variety of flow rates, including low flow rates. The nozzle is particularly beneficial for vertical manifold arms with horizontally mounted nozzles because the trajectory distance is constant for a wide range of flow rates. The nozzle achieves these benefits by providing a fixed flow path and a variable flow path. The nozzle includes a substantially spherical poppet having a fixed hole orifice, variably retained by a spring adjacent to the orifice of the discharge port.
