Abstract

Improvements in irrigation apparatus, for drip or light blast irrigation systems, characterized by the fact of having an outer cover or casing provided with an internal thread and provided with an externally threaded plug, inserted in said casing, both threads having such dimensions that between them a spiral unwinding duct is formed that leads, directly or through a labyrinth groove, to an outlet of the apparatus, a flow regulating device being placed at the inlet of said spiral duct, a flow regulator consisting of a disc perforated of elastic material, widening or narrowing the passage existing in said regulator in inverse relation to the pressure at which the flow reaches said disk.
