Abstract
Drip irrigation emitters having low activation pressures, desirable flow rates, and are configured to clog less than existing emitters are provided. The disclosed emitters include membrane cavities that are devoid of a channel and a land to help advance fluid through the cavity, to an outlet, and to an outside environment. Instead, the membrane cavities have various shapes and configurations that, in conjunction with a depressed membrane, help to drive fluid out of the membrane cavity and to an outside environment. The shapes of the membrane cavities include a sinusoidal configuration, a cylindrical shape configuration, and a flat bottom configuration. Various features of such emitters, and methods of using the same, are also provided.
