Patent number: 8870098Abstract: A flat type pressure regulated drip emitter with a non-drain valve capabilities that is installable inside a water supply conduit during the conduit manufacturing process and characterized by that the emitter's non-drain valve function is executed independently and separately from its pressure regulation function, through a portion of the emitter's elastomer component that is strained and biased against the emitter's water inlet opening and is moveable towards and away from an additional opening (additional to the emitter's water outlet opening), exposed to the pressure prevailing in the emitter's water exit pool and therefore, at any given time, this portion of the elastomer component is exposed to the maximum differential pressure that prevails in the system—on its one side to the water pressure prevailing in the water supply conduit and on its other (second) side—to the approximate atmospheric pressure.Type: GrantFiled: December 15, 2011Date of Patent: October 28, 2014Assignee: Plastro Irrigation Systems Ltd.Inventors: Moshe Lutzki, Zvika Einav

Patent number: 8205638Abstract: A fluid pressure regulator with a no-drain valve where the no drain valve also serves as a pressure reactive member to operate the pressure regulator valve. At low pressure settings, the no-drain valve is biased closed, and the regulator is biased open. As pressure progressively rises, the no-drain valve opens, then abuts a piston component of the regulator valve, and as pressure continues to rise, moves together with the regulator piston to move the regulator valve toward a closed position, thus regulating pressure.Type: GrantFiled: July 25, 2006Date of Patent: June 26, 2012Assignee: Plastro Irrigation Systems Ltd.Inventors: Zvika Einav, Moshe Lutzky, Asaf Katzin

Publication number: 20120012682Abstract: A dripper unit adapted to be integrally bonded to an internal surface of a conduit. The unit being of the flat “boat-like” type and is made of solely two parts—an elongated body member formed on its one side that is intended to be affixed unto an inner wall of the conduit with an elongated water exit “pool”; and on its opposite side constructed with a throttle means and with a flow passage formed between them; and the second part is means for defining a flow passage between said means and said body. The dripper unit characterized in that the means for defining a flow passage is formed as an elongated flat thin sheet which is adapted to be bonded to the elongated body member while covering and therefore defining underneath, at least a flow-restricting flow path.Type: ApplicationFiled: February 17, 2010Publication date: January 19, 2012Inventor: Zvika Einav

Patent number: 8096491Abstract: 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 aType: GrantFiled: October 19, 2006Date of Patent: January 17, 2012Assignee: Plastro Irrigation Systems Ltd.Inventors: Moshe Lutzki, Zvika Einav

Patent number: 7913935Abstract: An in-line system of mini sprinklers comprising a tubular conduit having inner and outer surface areas, and fitted for the flow of pressurized liquids. This tubular conduit has one or more openings along its length, and at least one mini sprinkler unit embedded within the tubular conduit at each opening. Each mini sprinkler unit comprises a liquid distributing assembly and biasing means. As pressure within the tubular conduit increases, inward force exerted by the biasing means is overcome, and the liquid distributing assembly moves outward. As the liquid distributing assembly protrudes beyond the outer surface of the tubular conduit, liquid escapes and sprinkles onto the ground. As pressure is decreased within the tubular conduit, the biasing means force the liquid distributing assembly back to its original position.Type: GrantFiled: February 21, 2006Date of Patent: March 29, 2011Assignee: Plastro Irrigation Systems Ltd.Inventors: Zvika Einav, Zvi Golan

Publication number: 20090165863Abstract: 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 regulaType: ApplicationFiled: July 25, 2006Publication date: July 2, 2009Inventors: Zvika Einav, Moshe Lutzky, Asaf Katzin
