<p>The sprinkler hose (1) is swivel mounted (19) to a lever (2) fitted with a pin (4) pointing into the jet (5) released from the hose (1). The Z-shaped lever (2) is permanently joined to a bow (3) with a linear extension (6) attached to a sliding element (7). When an operating wheel (16) is turned, a shaft (10) with a threaded central segment (11) is rotated inside a threaded sleeve (8) held at a guiding element (9). The pin (4) is moved within the jet (4) by the motion of the bow (3) and deflects the stream of water (4) as required.</p> |
