Abstract:

A rotatable impact sprinkler is disclosed herein and includes a nozzle through which a jet of water issues and an oscillating arm having an end movable in front of and to one side of the nozzle. The sprinkler also includes a water deflector which is connected with this end of the oscillating arm and which is movable into and out of the water jet. The deflector includes three water deflecting surfaces which receive and redirect water from the jet in a smooth, substantially turbulent free manner. This water is first redirected along a first straight path at least approximately 90. degree. from the axis of the jet. It is then redirected along a second path at an acute angle with and in front of the first path and thereafter it is redirected along a third path which is approximately parallel with the axis of the issuing jet.
