Abstract (en)

A water passage for embedded rotary sprinkler includes upper (10) and lower (20) tubes and upper (30) and lower (40) covers so as to form first (100) and second (200) independent chambers, integral water path (300), and upper (400) and lower (500) independent chambers. The first (100) and lower (500) independent chambers have clockwise (26) and counter-clockwise (27) water paths. An outer ring water path (25) connecting the first independent chamber (100) is formed to the lower tube (20). A transmission gear (600) is arranged inside the second independent chamber (200). A driving shaft (80) having an upward open is arranged between the second (200) and the lower (500) independent chambers. An upper end of the driving shaft (80) is connected with a nozzle, and a plurality of lateral holes (84) are formed in the middle of the driving shaft (80) in the upper dependent chamber (400). A lower end of the driving shaft (80) having a gear (83) engaging the transmission gear (600) is inside the second independent chamber (200).
