Abstract
An improved sprinkler (2) includes a body (4) which includes a pop-up nozzle (10). Nozzle (10) is sufficiently smaller than body (4) to create a gap therebetween as nozzle (10) rises out of body (4). An annular guard (30) separate from nozzle (10) is located in the upper end of body (4) and is normally urged out of body (4) by a spring (34). Guard (30) is normally engaged by a cover (18) on nozzle (10) so that nozzle (10) normally keeps guard (30) retracted within body (4). However, as nozzle (10) rises from body (4), guard (30) will be projected upwardly substantially as soon as nozzle (10) rises to immediately seal the gap. Stops (40) and (42) are provided on guard (30) and body (4) for limiting the upward movement of guard (30) to an amount less than the upward movement of nozzle ( 10).
