Abstract

A discrete flat dripper of the non-pressure regulated type of drippers or of the pressure compensated—flow rate regulated type of drippers, suited for being integrally installed within a hose, that comprises a body component whose configuration is essentially rectangular, wherein on its one side that is suited to being affixed to an internal wall of the hose, formed with an exit pool that it is elongated in its dimensions and substantially extends along the entire length of the body component, and with a flow passage circumferentially surrounding a substantial part of the elongated exit pool, and an integral dripper line wherein there are integrated at least one of such discrete flat dripper, and optionally and as enabled by the elongated exit pool, the water outlet opening that is formed at the hose wall opposite the elongated exit pool and within its boundaries, is in a configuration of a thin and long slit.

First claim

The invention claimed is:

1. A discrete flat dripper that is suited for being integrally installed within a hose, comprising:
a substantially rectangular body component configured to affix to an internal wall of said hose;
an elongated exit pool formed on said body component and substantially extending along a length of said body component; and
a circumferential flow passage circumferentially surrounding a substantial part of said elongated exit pool for routing the water that entered into the dripper towards said exit pool, wherein said circumferential flow passage comprises
a filter,
a water pressure reducer,
a transverse flow passage that connects a first end of said filter to a first end of said water pressure reducer; and
a water exit opening that connects, for flow passage of filtered and pressure reduced water, from a second end of said water pressure reducer to said elongated exit pool;

wherein the dripper is of a non-pressure regulated type dripper, and wherein said filter extends along and parallel to a first side of said elongated exit pool, and said water pressure reducer extends along and parallel to a second side of said elongated exit pool, the second side and the first side of said elongated exit pool being opposite each other; and wherein said transverse flow passage transverses across the width of said body component proximate a first end of said body component, and said water exit opening is formed at a second end of said body component, the second end and the first end of said body component being opposite each other and orthogonal to the first and second sides of said elongated exit pool.

2. The discrete flat dripper in accordance with claim 1 , wherein said elongated exit pool has elongated dimensions and substantially extends along an entire length of said body component, defining a lengthwise axis so that said circumferential flow passage is formed in a substantially symmetrical manner relative to the lengthwise axis.

3. The discrete flat dripper in accordance with claim 1 , wherein said filter comprises:
an array of slots that are connected for flow of water through the array of slots from the first side of said body component that, from the instant of affixing said body component to said inner wall of said hose, are directed towards the inside of the hose, and
a routing channel that extends along an entire length and parallel to said exit pool, coupled for passage of filtered water flow into the routing channel from said array of slots, and routes filtered water on towards said transverse flow passage.

4. The discrete flat dripper in accordance with claim 1 , wherein said water pressure reducer comprises a baffles array resembling a labyrinth that is formed with a water pressure reducer passage through the baffles array, and wherein a first end of said water pressure reducer passage is coupled to said transverse flow passage and a second end of said water pressure reducer passage is coupled to said water exit opening.

5. The discrete flat dripper in accordance with claim 1 , wherein said exit pool comprises a circumferential walls array that separates said filter, said water pressure reducer and said transverse flow passage.

6. The discrete flat dripper in accordance with claim 1 , wherein said elongated exit pool has elongated dimensions and substantially extends along an entire length of said body component, defining a lengthwise axis so that said filter and said water pressure reducer are formed in a substantially symmetrical manner relative to the lengthwise axis.

7. A discrete flat dripper that is suited for being integrally installed within a hose, comprising:
a substantially rectangular body component configured to affix to an internal wall of said hose;
an elongated exit pool formed on said body component and substantially extending along a length of said body component, wherein said elongated exit pool has elongated dimensions and substantially extends along an entire length of said body component, defining a lengthwise axis so that said circumferential flow passage is formed in a substantially symmetrical manner relative to the lengthwise axis; and
a circumferential flow passage circumferentially surrounding a substantial part of said elongated exit pool for routing water that entered into the dripper towards said exit pool, wherein said circumferential flow passage comprises
a filter,
a water pressure reducer,
a transverse flow passage that connects a first end of said filter to a first end of said water pressure reducer; and
a water exit opening that connects, for flow passage of filtered and pressure reduced water, from a second end of said water pressure reducer to said elongated exit pool;

wherein the dripper is of a non-pressure regulated type dripper, and wherein said filter extends along and parallel to a first side of said elongated exit pool, and said water pressure reducer extends along and parallel to a second side of said elongated exit pool, the second side and the first side of said elongated exit pool being opposite each other; and wherein said transverse flow passage transverses across the width of said body component proximate a first end of said body component, and said water exit opening is formed at a second end of said body component, the second end and the first end of said body component being opposite each other and orthogonal to the first and second sides of said elongated exit pool.

8. The discrete flat dripper in accordance with claim 7 , wherein said filter comprises:
an array of slots that are connected for flow of water through the array of slots from the first side of said body component that, from the instant of affixing said body component to said inner wall of said hose, are directed towards the inside of the hose, and
a routing channel that extends along an entire length and parallel to said exit pool, coupled for passage of filtered water flow into the routing channel from said array of slots, and routes filtered water on towards said transverse flow passage.

9. The discrete flat dripper in accordance with claim 7 , wherein said water pressure reducer comprises a baffles array resembling a labyrinth that is formed with a water pressure reducer passage through the baffles array, and wherein a first end of said water pressure reducer passage is coupled to said transverse flow passage and a second end of said water pressure reducer passage is coupled to said water exit opening.

10. The discrete flat dripper in accordance with claim 7 , wherein said exit pool comprises a circumferential walls array that separates said filter, said water pressure reducer and said transverse flow passage.

11. The discrete flat dripper in accordance with claim 7 , wherein said elongated exit pool has elongated dimensions and substantially extends along an entire length of said body component, defining a lengthwise axis so that said filter and said water pressure reducer are formed in a substantially symmetrical manner relative to the lengthwise axis.

12. A discrete flat dripper that is suited for being integrally installed within a hose, comprising:
a substantially rectangular body component configured to affix to an internal wall of said hose;
an exit pool formed on said body component and substantially extending along a length of said body component; and
a circumferential flow passage circumferentially surrounding a substantial part of said exit pool for routing water that entered into the dripper towards said exit pool, wherein said circumferential flow passage comprises
a filter extending along a first side of said exit pool,
a water pressure reducer extending along a second side of said exit pool, the se
