A drip emitter comprising:
- an emitter body comprising:
- an inner side having a recess formed therein;
- and
- an outer side opposite the inner side;
- and
- an emitter cover comprising:
- a frame having a periphery and an opening within the periphery;
- and
- a membrane located in the opening and bounded by the periphery, the membrane having a membrane surface area A2, a first portion of the membrane constituting a regulating part having a regulating part surface area A1 smaller than the membrane surface area A2, with 0.7≤A1/A2≤0.9;
- wherein:
- the emitter cover is configured to cover a portion of the inner side of the emitter body, with the membrane's regulating part overlaying the recess to form a pressure regulating chamber between the membrane's regulating part and the recess, in an assembled operative state of the drip emitter.
