摘要

A swivelling fan-jet sprinkler which is convertible from a coarse sprinkling mode in which it covers a relatively large irrigation area to a gentler spraying mode in which it covers a smaller area, the conversion being achieved by means of a removable spinner cage which surrounds the nozzle cylinder of the sprinkler. The spinner cage has a captive snap ring cooperating with a groove in the nozzle cylinder to produce a detent action for attachment and removal of the spinner cage. The latter is driven by the water jets which are disturbed in the process.
