Abstract
A sprinkler nozzle for use in irrigation having an inlet, an outlet and a flow passage extending between the inlet and the outlet. The outlet and the flow passage each have near stream and far stream portions and the nozzle is unpartitioned between the near stream and far stream portions so that a single stream can be emitted from the outlet. The far stream and near stream portions of the flow passage are configured to provide higher velocity less turbulent flow through the far stream portion of the outlet than through the near stream portion of the outlet. The nozzle includes a peripheral wall which has a main body and a hood with the hood being radially offset from the main body to form an opening. The nozzle is received in a bore and nozzle mounting structure of a spray head for a sprinkler. The hood has an abutment partly defining the opening which is engageable by a tool for withdrawing the nozzle from the bore.
