Publication number: 20210037728Abstract: A drip emitter is provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. Water enters the emitter through a first inlet and proceeds into a first chamber. When the water pressure is above a predetermined level, a one-directional valve opens to allow fluid flow past the first chamber, through a tortuous path flow channel, and through an emitter outlet. A second inlet is used to compensate for water pressure fluctuations in the supply tube to maintain output flow at a relatively constant rate. Water enters the second inlet and presses a flexible diaphragm toward a water metering surface to provide pressure-dependent control of the output flow. A copper member is mounted to the emitter over the emitter outlet to prevent plant root intrusion into the emitter outlet.Type: ApplicationFiled: October 22, 2020Publication date: February 11, 2021Inventors: Rick Mavrakis, Brian Pope, Samir Shah, Christopher Leland O'Neal, David R.

Publication number: 20140001287Abstract: Drip tubing is provided that has a first flow path and a second, independent flow path. A plurality of first drip irrigation devices are associated with the first flow path for dispensing fluid from the first flow path at a first precipitation rate. A plurality of second drip irrigation devices are associated with the second flow path for dispensing fluid from the second flow path at a second precipitation rate. The first and second drip irrigation devices are preferably different, and the first and second precipitation rates are also preferably different. One of the drip irrigation devices may be a drip emitter discharging drips of fluid and the other may be discharge fluid in a spray pattern.Type: ApplicationFiled: July 21, 2011Publication date: January 2, 2014Inventor: Rick Mavrakis
