Abstract
A wave sprinkler assembly in which the tubular spray assembly comprises a tubular member and one or more elongated strips of flexible material having a series of longitudinally spaced water stream outlets extending therethrough, the strips are assembled with the tubular member by inserting them therein through an end and moving them radially outwardly into an operative position wherein the water under pressure within the interior of the tubular spray assembly acts on the strips to enhance their engagement with the tubular member. The strip provides an annular seal of flexible sealing material extending around the exterior of each of the controllable water stream outlets, and a control member is mounted on the elongated tubular assembly for movement between a full width operating position and a width limiting position. The control member includes a control section associated with each annular seal and the controllable water stream outlet around which it extends. Each control section has a surface area movable into engagement with the associated annular seal to prevent a water stream from issuing from the controllable water stream outlet around which it extends and an open area movable over the controllable water stream outlet around which the associated annular seal extends to allow a water stream to issue therefrom.
