ABSTRACT:
Several embodiments of drip emitters are disclosed. These embodiments comprise (1) a molded plastic, body with an upwardly opening housing, and (2) a molded plastic plug including an enlarged head, a depending shank, and a helical thread defined about the perimeter of the shank. The body is executed in a relatively soft plastic, while the plug is executed in a harder plastic. The shank of the plug is press-fitted into the housing, and the threads on the shank of the plug cut into the softer plastic of the housing. By advancing or retracting the plug, the length of the helical flow path is altered and the rate of discharge of droplets from the emitter is changed to account for changes in line pressure, accumulation of debris in the emitter, and other operational parameters.
