ABSTRACT:
A sprinkler includes a sprinkler body having an inlet end and an outlet end, the outlet end having a nozzle with a discharge orifice; the nozzle surrounded by an outer wall forming an annular chamber radially spaced from the discharge orifice. A rotor plate is supported by the sprinkler body for rotation about an axis, the rotor plate having a tubular water distribution passage with an inlet and an outlet, the passage configured to cause the rotor plate to rotate when a stream from the nozzle passes therethrough. The inlet of the passage is axially spaced from the discharge orifice by a distance sufficient to aspirate air into the inlet end of the passage, thereby pulling water leaked into the chamber back into the passage.
