<p>The static irrigation sprinkler has a passage delivering water through the body to a calibrated outlet. The latter discharges a jet against a cap (6), which distributes it radially, and is joined by columns (11) to the body. The cap can have a central flat portion onto which a conical or parabolic surface joins. The columns can be triangular sections with straight or rounded bases and sharp or slightly radiused apexes. The windows formed between two adjacent columns can have parallel faces, and the columns can be welded or glued to the body or snap into engagement with it.</p> |
