Abstract
An irrigation sprinkler is provided having a turret for the distribution of irrigation water that includes a self-flushing mechanism to prevent accumulation of debris in a sprinkler control member and/or the interior of the turret. The sprinkler includes a main flow path that delivers water to a nozzle for irrigation and a secondary flow path that delivers water to flush part of the member and/or interior of the turret. The secondary flow path delivers water when the sprinkler cycles on and when the sprinkler cycles off. For example, with a pop-up sprinkler, the secondary flow path would deliver fluid sometime during its movement to the elevated position and movement to the retracted position.
