Abstract:
1. A revolving sprinkler that comprises: a rotatable turret assembly rotatable around a rotation axis, wherein said assembly is adapted to receive a flow of a liquid under pressure, a first mouthpiece for mounting in said assembly to sprinkle said liquid at a first predetermined throughput at a given liquid pressure; said mouthpiece including a nozzle having a flow outlet located at a first moment arm linear distance from said rotation axis, and wherein liquid exiting the nozzle imparts to said assembly a driving moment that causes rotation of the turret assembly around said rotation axis; and a base assembly that serves as a bearing for rotation of said rotatable turret assembly around said axis and routes said flow of liquid under pressure to said turret assembly; and a second mouthpiece, for replacing said first mouthpiece, the second mouthpiece sprinkles said liquid at a second predetermined throughput at the given pressure, the second mouthpiece including a nozzle having a flow outlet located at a second moment arm linear distance from said rotation axis when the second mouthpiece is mounted in said turret assembly in place of said first mouthpiece, said second throughput being different from the first throughput and said second distance being different than said first distance; and wherein, said second distance is such that after replacing said first mouthpiece by said second mouthpiece, the driving moment that causes the rotation of said turret assembly remains essentially equal to the driving moment generated when said first mouthpiece was mounted in the assembly.
