Abstract:
An elastomer membrane based regulated drip emitter, wherein the elastomer membrane has a regulating membrane portion that separates between the inlet and outlet side, so that upon installing the elastomer component and locating it at the internal space of the drip emitter's housing assembly, the said first embedded space is connected to a water flow passage from the water inlet opening of the drip emitter and the outlet side is located facing the drip emitter's flow control and water outlet opening. The drip emitter is characterized by that the elastomer component is anchored around its circumference to the drip emitter's housing assembly and to the cover component of the drip emitter upon installing of the elastomer component and locating it at the internal space of the emitter's housing assembly opposite the cover component, in order to prevent the elastomer component from moving away from the walls of the internal space during the regulating membrane movements.

Abstract:
The present invention relates to an irrigation system, comprising at least one tubular conduit means, that has a thin wall, such that it is capable of being essentially flattened, connectable to a water passage into it from a water source such that water entrance into it results in its widening into a configuration that is not essentially flat. The system further comprises: a plurality of connector components located along the length of said tubular conduit means and protruding from its external surface area that are adapted to selectively enable anchoring of irrigation extensions into them, in a manner that enables connecting said irrigation extensions for allowing water entrance into them from said tubular conduit means; a connector assembly, that enables connecting said tubular conduit means in series with an at least one additional such tubular conduit means; and wherein said irrigation system is characterized by that said connector assembly enables a face to face connection of a portion of said tubular conduit means wall with another portion of said additional tubular conduit means wall in order to seal said connection against leakage of water.

Abstract:
An elastomer membrane based, regulated drip emitter unit, equipped with a non-drip valve, wherein the drip emitter is characterized by that it includes an opening that is exposable to an approximate atmospheric pressure that prevails on the water outlet from the drip emitter; and an additional elastomer membrane portion that is strained and biased against the water inlet opening of the drip emitter for creating a seal with its one side for a non-drain valve and on its other (second) side it is connected to that atmospheric pressure prevailing opening, and wherein the elastomer membrane portion is movable towards that opening in order to open the water inlet opening for enabling a water flow passage from a water supply conduit to the drip emitter, and this from the specific instant that the force exerted by the water pressure prevailing in the water supply conduit on one side of that elastomer portion, overcomes the strain at which that portion was strained and biased against the water inlet opening, as well as the approximate atmospheric pressure that prevails on the other side of that elastomer portion.
Abstract:
A fluid pressure regulator with a no-drain valve, characterized in that - when the fluid pressure decreases at the regulator's flow inlet to pre-set level, a no-drain spring means of the regulator, overcomes the force exerted by the fluid pressure upon the regulator's no-drain valve component and a protruding shoulder formed around its circumference, pushing a no-drain piston assembly of the regulator and stresses its no-drain valve component towards an exit flow control opening formed in the regulator, to the fully closed state of the regulator's no-drain valve component; and upon an ongoing increase of the fluid pressure at the flow inlet to a pre-set level that is still lower than the designed regulated pressure of the regulator or at most equal to the designed regulated pressure of the regulator, the force that the fluid pressure exerts on the protruding shoulder surface area formed around the circumference of the regulator's no-drain valve component, overcomes a no-drain spring means and propels the regulator's no-drain piston assembly and with it, the no-drain valve component, upon a bushing component within a cylinder assembly and through its second, open opposite end of that cylinder assembly, while opening an exit flow control opening to fluid passage from the flow inlet of the regulator to its flow outlet; and with a further increase of the fluid pressure at the flow inlet to a level higher than the designed regulated pressure of the regulator, and in order to control the flow through the regulator towards the flow outlet from its housing assembly, the regulator's no-drain piston assembly drives a bushing component carried upon a rod component to move together - the regulator's no-drain piston assembly and its piston assembly, towards a flow control opening formed in the regulator's housing assembly.
