Abstract
Pressure-compensating emitter. The emitter includes an inlet connected to a source of pressurized water and an orifice in fluid communication with the inlet and extending into a channel including a raised land surrounding an outlet. A compliant membrane is positioned above the land in the chamber wherein pressurized water will cause the membrane to deform into contact with the land to alter flow through the outlet so as to provide a constant flow rate. Parameters of the emitter are selected so that the emitter has a large operating range and an activation pressure of 0.15 bar or below.
