Abstract
A pulsating sprinkler utilizes an improved method of anchoring the helical torsion spring at one end to the sprinkler body and at the other end to the impact arm to facilitate the assembly process and provide a more reliable and uniform spring action. A radially ridged member adapted for connection to a fluid source carries a pair of sector stops, each extending totally about a circumference thereof and having a single tab enabling rotation of the sector stop in both directions. When employed as a full circle sprinkler, the sprinkler automatically corrects the direction of rotation of the sprinkler body in the event that it initially rotates in the wrong direction.
