ABSTRACT:
A rotary, pop-up sprinkler is provided which includes an in-ground container. A motor is reciprocably mounted in the container and includes a stator, a plate assembly mounted on the stator and a rotor rotatably received in the stator. The rotor includes a turret with a nozzle orifice. Hydraulic pressures on the rotor are balanced whereby anti-rotational drag is substantially reduced. A speed regulator is provided for maintaining a relatively constant rotational speed when the sprinkler is subjected to variances in hydraulic pressure.
