Flow reducing devices particularly useful as drip emitters for drip irrigation

摘要

Flow-reducing devices particularly useful as drip emitters comprise a housing having a closure cap snap-fitted thereto and enclosing a flow- retarding member formed with a plurality of recesses on opposite faces each recess bridged by a pair of holes to provide a serial path for the flow of the water through the holes from one face to the opposite face. Also described is the use of a regulator including a valve member sensing the fluid pressure at the inlet of the device to produce a substantially uniform output of water despite variations in the line pressure at the inlet.
