  • An important feature of the illustrated embodiment is the manner in which the variously-described structural features combine to accurately align the nozzle insert 14 in the ON position. More specifically, the centerline of the nozzle bore 36 must be positioned within +.005" of the sprinkler body flow passage centerline in the left to right and fore to aft directions, and must be positioned rotationally about axis A within ⁇ .5°. The combination of water pressure and seal compression forces the insert 14 (and hence the insert body 34) against ribs 136 and 138 and thereby accomplishes the left-to- right centering.

  • the user can push and turn (easier option) or just turn (more torque required) the nozzle insert 14 until rotation begins. Then, if the user continues turning without pushing, the nozzle insert body 34 will click into the next set of index notches. This rotation and spring action will accurately locate the nozzle insert so long as the nozzle insert is sufficiently free to move axially and
  • nozzle insert To insure the required freedom of movement of the nozzle insert, generous clearances are maintained between the nozzle insert and the sprinkler body wherever possible (such clearances cause the water spray mentioned above that is shielded by the forward end wall 60) . Further in this regard, the nozzle insert itself is formed to permit water to leak past the seal 154 during position changes to flush out impacted sand, etc.
