Claim 0:
1. A sprinkler comprising:
a sprinkler body with a longitudinal axis;
a nozzle;
a deflector plate assembly secured in the sprinkler body and including a deflector plate facing the nozzle and disposed at a first outermost end of the deflector plate assembly, the deflector plate having a rotational axis, wherein the deflector plate assembly is configured for rotation on the rotational axis of the deflector plate and is configured to wobble by orbital motion about a central point of the deflector plate assembly; and
a pitch member cooperable with the deflector plate assembly, the pitch member being separate from and spaced from the nozzle and separate from and spaced from the deflector plate and positioned adjacent a second outermost end of the deflector plate assembly opposite from the first outermost end, wherein the pitch member is configured to maintain the deflector plate assembly and thereby the deflector plate at an angle relative to the sprinkler body such that without the pitch member, the deflector plate assembly and the deflector plate would be unable to be maintained at the angle relative to the sprinkler body, and wherein the pitch member is a one-piece stationary member that is positioned to prevent the deflector plate assembly from assuming an orientation in alignment with the longitudinal axis of the sprinkler body in use, at rest, and when fully assembled.
