Patent ID: 8434695

Claim:
A rotary sprinkler, comprising: a body member including a water inlet nozzle having a top end and a bottom end, a pressurized water connector communicating with the bottom end of said water inlet nozzle, and a ring attached to the body member in spaced-apart relationship from the top end of the nozzle, the body member further comprising a cup having a bottom end fluidly coupled to the water inlet nozzle, and being open at its top end but otherwise being substantially closed and housing said rotor member in non-operative states of the sprinkler, a rotor member having at a first end an opening configured for receiving water from said inlet nozzle and for directing it to a water distributing groove, and said rotor member having an axle at a second end opposite the first end and protruding through an annular cover that is integral with the rotor member and is supported at the second end thereof so as to cover the top end of the cup in non-operative states of the sprinkler with the rotor member housed inside the cup and thereby prevent entry of insects or other matter that might otherwise tend to clog the nozzle, and a rotor axle seat member engageable and disengageable with the axle of said rotor member and with said ring, said ring being of larger diameter than the rotor member so as to allow axial removal of the rotor member through the ring upon disengagement of said rotor axle seat member from the ring.
