Patent number: 8511585Abstract: A drip irrigation emitter has first and second inlets through which liquid enters the emitter from an irrigation pipe, an outlet through which liquid exits the emitter, and a first flexible diaphragm portion seated on the second inlet and serving as a valve. Liquid at a pressure in the pipe that is below a predetermined level enters the emitter via the first inlet and travels along a first flow restricting path before exiting via the outlet and liquid at a pressure in the pipe that is above the predetermined level biases the first flexible diaphragm portion so that liquid can enter the emitter via the second inlet and travels along a second flow restricting path before exiting via the outlet.Type: GrantFiled: December 21, 2009Date of Patent: August 20, 2013Assignee: Netafim, Ltd.Inventor: Ron Keren
