Claim:
An oscillating water sprinkler, comprising: a spray structure having a plurality of outlets; a support structure which supports said spray structure, said spray structure being movable in relation to said support structure in an oscillating pattern of movement; an inlet supported by said support structure and configured to be coupled to a hose; and a valve mechanism interposed between said inlet and said plurality of outlets, said valve mechanism defining a water flow aperture providing fluid communication between said inlet and said plurality of outlets, wherein, during said oscillating pattern of movement, said spray structure oscillates in relation to said support structure between a first position and a second position, wherein, as said spray structure moves between said first position and said second position during said oscillating pattern of movement, said support structure passes through a central position, and wherein, as said spray structure moves from said central position to one of said first position and said second position during said oscillating pattern of movement, (i) said water flow aperture increases in size, and (ii) said water flow aperture never decreases in size.
