<p>An oscillating lawn sprinkler (4) comprises a pipe (7) provided with spray nozzles and pivotally mounted on a bearing block (5). The spray pipe (7) is driven by the water pressure through a turbine-type motor enclosed in a driving mechanism box (6). The driving box (6) is connected with the water supply hose on one side and with one end of the spray pipe (7) on the other side. Means (21) for adjusting the flow rate of the water delivered by the spray pipe and means for adjusting the oscillating range of the spray pipe are arranged, together with their control means (26, 9), on the side of the driving box (6) which is opposite to the one to which the spray pipe is linked. Filtering means (33) for the supply water are removably housed at the inlet side of the water connection fitting (8) of the driving box.</p> |
