Abstract (en)
[origin: EP0409251A2] A rotary sprinkler includes a rotor (210) rotatably mounted with respect to its nozzle and a retarding device having a first surface rotatable with the rotor, a second surface non-rotatable with respect to the nozzle (202), and a viscous liquid between the two surfaces. The first surface of the retarding device is a cavity (220) formed in the rotor, and the second surface of the retarding device is on a pin (222) non-rotatably mounted with respect to the nozzle and disposed within the cavity (220). The rotor further includes a cover (226) closing the cavity (220) and formed with an opening for receiving the pin (222), and a seal (228) carried by the cover (226) and including an annular sealing surface in contact with the pin (222) to seal the cavity, the annular surface of the seal being located so as to be continuously immersed in the viscous liquid in the cavity.
