Technical Examples

A sprinkler head having a deformable member forming a collar is disclosed. The deformable member allows the sprinkler head to resist entry of foreign grit or matter within the sprinkler head, and allows the sprinkler head to eject or force out foreign matter from within the sprinkler head. The sprinkler head may be a spinning sprinkler head including a vane deflector, and the spinning sprinkler head may include a portion that shifts in response to being struck by water such that a braking mechanism is engaged in response to the force of the water. When water flow ceases, the spinning head may shift towards the deformable member so that a portion of the spinning head is received within the deformable member to restrict foreign matter from entering the sprinkler head.
