Claim 6:
7. A sprinkler comprising:
a sprinkler body with a longitudinal axis;
a nozzle;
a central support secured to or integral with the sprinkler body;
a deflector plate assembly secured by the central support and including a deflector plate facing the nozzle 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 relative to the central support and is configured to wobble by orbital motion about a central point of the deflector plate assembly; and
a pitch member configured to maintain the deflector plate assembly and thereby the deflector plate at an angle relative to the sprinkler body longitudinal axis, the pitch member being separate from and spaced from the deflector plate and positioned adjacent a second outermost end of the deflector plate assembly opposite from the first end, wherein 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.
