This internal flow-diverting means (19) is capable of taking, through angular displacements of the control means (15), corresponding positions for diverting the flow of water coming from a water inlet opening (13) in such a way as to deliver it to all of the spray nozzles (11) provided on the watering pipe (9) or to a part of them as provided on that portion of watering pipe (9) which is located either on the right-hand side or the left-hand side with respect to said flow-diverting means (19).</p> |
