Abstract
There is provided an online drip emitter that includes a check valve. The emitter uses a first diaphragm in the check valve and a second diaphragm spaced from the first diaphragm to provide pressure compensation. The second diaphragm communicates with a tortuous path and an outlet to regulate water emitting from the emitter depending on the supply pressure.
