摘要: An emitter formed by a pair of coterminous sheets adjacent one another and forming a discharge passageway extending from a source of pressurized water to a discharge outlet. A pressure sensitive chamber in communication with the pressurized water source is formed adjacent the exterior surface of each sheet by a half round section to bias the coterminous sheets toward one another and regulate the rate of water flow through the discharge passageway and discharge outlet.
