Abstract: A sprinkler or lawn spray of the reaction type has a flexible shield cooperating with a guide channel to direct the water emerging from the jet of the spray body in the desired direction and dispersal pattern. The shield may be of a flexible material or may be flexibly mounted to either the reaction arm or the spray body to preclude droplet distribution in a direction normal to the emerging stream from the spray jet. The shield is mounted either to the reaction arm or to the oscillating body of the spray. The stream guide channel may be open or closed and has an emerging reaction surface against which the jet stream impinges.
