Abstract

An improved constant flow rate dripper for drip irrigation systems comprises a case 2 having at one of its ends a seal for connection to a conduit and at the other end a water outlet port, a body 3 slidingly fitted in the case and a narrow annular space acting as a water passage between the head 16 of the body 3 and the case 2. An elastically deformable washer 5 rigid with the body 3 throttles a radial groove in a ring 4 fixed to the case 2, and a second elastically deformable washer 6 is press-fitted between the case 2 and the sleeve 7 which carries the conduit connecting spigot 8b. <IMAGE>
