A drip emitter has a flexible membrane for regulating a flow of liquid exiting the emitter. The membrane, in a non-stressed or non-flexed state into a regulating chamber of the emitter, includes a non-planar portion.

A drip emitter includes a frame, that can be made of plastic, and a membrane, that can be elastomeric; and both the frame and the membrane are formed by injection molding and are attached to each other.

An irrigation system is provided for irrigating a field divided into irrigation zones. The irrigation zones are arranged in columns extending alongside each other. The system has irrigation strips and a control head at an upstream end of each irrigation strip. Each irrigation strip provides irrigation substances to a column of zones. All control heads are located alongside a boundary of the field outside of the irrigation zones.

A membrane for a drip emitter includes at least two first and second regions. The regions are of different thickness.

A drip irrigation system includes a distribution pipe and drip irrigation pipes that branch off in communication with the distribution pipe. Each drip pipe has a flushing valve coupled to a downstream end and at least some of the drip pipes each have an inlet valve coupled to an upstream end for communication with the distribution pipe. The system further has at least one command valve in communication with the distributing pipe and also with at least some of the inlet vales, wherein opening of the command valve is configured to close the at least some inlet valves.

A valve assembly includes an inlet and an outlet, and has a first state where liquid is stopped from flowing from the inlet towards the outlet, a second state where liquid is released to flow from the inlet towards and out of the outlet, and a terminal state where after flowing out of the outlet, the liquid is stopped form flowing out of the outlet. An incoming command triggers the valve assembly from the first state towards the second state and, at or after reaching the terminal state, the valve assembly transmits an outgoing command.

Valve apparatus

A labyrinth channel for reducing pressure and/or flow rate in a liquid flowing in the channel, the labyrinth channel having a bottom surface and first and second opposing walls and comprising: a first array of spaced apart first baffle teeth that have non-parallel upstream and downstream faces and extend from the first wall towards the second wall to terminate in an end; and a second array of spaced apart second baffle teeth that have non-parallel upstream and downstream faces and extend from the second wall towards the first wall to terminate in an end; wherein baffle teeth in different arrays have a substantially same shape and upstream faces of closest baffle teeth in different arrays are different and/or downstream faces of closest baffle teeth in different arrays are different.
