ABSTRACT:
A sprinkler that restricts foreign particulate matter from interfering with and/or damaging the operating components of a sprinkler is disclosed. The sprinkler may be a pop-up sprinkler such that the outlet or nozzle is not in a fixed position and is moved from a position above the ground to a position generally below or flush with the ground. To prevent particulate matter from entering, such as through the nozzle or outlet, when the flow of water is shut off, the sprinkler may include a protective member located within the sprinkler head to prevent the particulate matter from have an undesirable effect. The protective member forms a one-way obstruction that permits flow to the nozzle and obstructs flow back into the sprinkler such that particulate matter in the water beyond the protective member is restricted from coming in contact with the internal operating components of the sprinkler. The protective member may be a resiliently deformable flap or a hinged flap.
