Micro stream emitter for use in irrigation systems
View Patent ↗The micro stream emitter include a body having two different geometries water outlet ports providing downward stream into the soil wetting the root zone and with the second geometries water outlet wetting the surrounding plants area. The internal passage of the emitter shown a the lower passage supplying water to the lower ports that actually uses top wall with a annular depression, forming a diaphragm enabling the water to reflex into the lower port outlets. Similar to the internal lower passage the upper passage with includes a smaller diameter passage uses top wall with an annular depression, forming a diaphragm enabling the water to reflex into the upper port outlets.
1. A micro stream emitter for use in irrigation systems comprising:
a unitary body defined by an upper portion and a lower portion;
a water inlet port disposed at an end of the lower portion configured for connection to a water supply;
a water channel extending longitudinally through the body from the inlet port along a central axis of the body;
a plurality of first water outlet ports being disposed within the upper portion and in communication with the water channel, each first outlet port extending approximately ninety degrees from the water channel;
wherein each of the plurality of first outlet ports are radially spaced from each other to define a three hundred and sixty degree spray pattern;
a plurality of second water outlet ports being disposed longitudinally between the plurality of first outlet ports and the inlet port and in communication with the water channel, each second outlet port extending approximately thirty to sixty five degrees from the water channel;
wherein each of the plurality of second outlet ports are radially spaced from each other to define a three hundred and sixty degree spray pattern; and
wherein an upper portion of the water inlet channel has a concave surface just above the plurality of first water outlet ports.
