Abstract
Drip irrigation devices (10, 40, 90) to facilitate the flushing of the irrigation system are provided. The devices (10, 40, 90) include an upper body portion (12, 42, 96) having an intake passageway (24, 55, 106) and opening (56, 104), and a lower body portion (16, 46, 98) having a discharge passageway (29, 66, 106') and opening (76, 104). A floating or stationary disk (14, 44, 114) is positioned between the upper and lower body portions. During the flush cycle, the disk (14, 44, 114) oscillates with great energy to loosen debris and flushes particles and debris out of the irrigation lines. During the irrigation cycle, the disk provides pressure-compensated regulation of water flow to permit drops of water or solution to form.
