Abstract
A constant drive nozzle for use in combination with an impulse or impact drive sprinkler includes a tubular nozzle body with a drive orifice and a range orifice formed in its outlet end. The stream issuing from the nozzle is formed into a drive stream portion and a range stream portion by the drive and range orifices. Since only the drive stream portion intercepts the drive spoon of the arm which impacts and rotates the sprinkler body, various diameter range orifices can be used in conjunction with a single diameter drive orifice without affecting the rotational speed of the sprinkler body.
