Abstract
An irrigation spray device has a substantially cylindrical peg for insertion into a water supply tube. A longitudinal water supply groove extends along the peg, with a water deflecting plate at one end of the groove for deflecting water traveling downwardly along the groove into an outwardly directed spray. The water deflecting plate has a smooth, convex curved or part-conical shape for forming a smooth, continuous, cone-shaped spray. The supply groove may be U-shaped for improved uniformity.
