Rotary sprinklers are described comprising a nozzle having an axial bore for forming an axial jet, and a rotor floatingly mounted for axial and rotary movement, the underface of the rotor being formed with a pair of grooves from its center to its outer edge for deflecting the axial jets laterally of the sprinkler and for imparting a rotary motion to the rotor. The rotor further includes a stem depending from its underface and received within the nozzle bore, which stem is formed with a pair of grooves extending axially thereof and merging with the radially-extending grooves in the underface of the rotor. Also described are various arrangements for floatingly mounting the rotor by means of a spindle, a cap, or a bridge. |
