摘要:
A drip irrigation emitter comprising an emitter inlet, an emitter outlet, an irrigation fluid path extending therebetween including a pressure-reducing mechanism configured to convert fluid flow entering the emitter inlet under pressure, into a drip flow from the outlet; a space via which the pressure reduced fluid has to pass in order to reach the emitter outlet; and a mechanism based on a fluid-accumulation chamber which is configured for being brought into fluid communication with an exterior of the emitter for receiving therefrom at least indirectly an accumulatable fluid and further configured to allow introduction of the accumulatable fluid into a chamber to cause the chamber to change over time its state between a first state, in which the amount of said accumulatable fluid in the chamber is minimal and a second state, in which the amount of the accumulatable fluid in the chamber is maximal and in which fluid communication between the pressure-reducing mechanism and the emitter outlet is prevented, wherein the emitter is characterized by a further one-way valve having a valve inlet downstream from the pressure-reducing mechanism and a valve outlet upstream to said space and configured to allow the drip flow from the valve outlet into said space as long as fluid pressure differential between the valve inlet and the valve outlet is not less than an operational pressure differential, and wherein the a fluid-accumulation chamber mechanism is configured to change a state of the fluid irrigation path between a first, operational state allowing said drip flow via said valve and said space towards the emitter outlet, and a second state in which fluid communication is prevented between said space and the emitter outlet, causing the pressure differential at said valve to drop below the operational pressure differential.
