US 2026/0231879 A1 · IRRIGATION EMITTER

Abstract

An emitter includes a base having a top, a bottom, a first end, a second end, a first side, and a second side. The base includes a pressure reducing portion. The top includes an inlet receiver in communication with a first portion of the pressure reducing portion. The bottom includes an outlet bore in communication with a last portion of the pressure reducing portion. At least one intermediate portion interconnects the first and last portions, and portions of the pressure reducing portion are in communication in series between the inlet receiver and the outlet bore to form a portion of an irrigation flow path. Each portion of the pressure reducing portion includes a first path portion with a first diameter and a second path portion with a second diameter, which is different than the first diameter to create a pressure loss when flowing through the pressure reducing portion.

An emitter for use with a lateral to form an irrigation lateral, the lateral including a lateral wall having an inner surface and an outlet aperture, comprising:

a base having a top, a bottom, a first end, a second end, a first side, and a second side, the base including a pressure reducing portion, the top including an inlet receiver in fluid communication with a first portion of the pressure reducing portion, the bottom including an outlet bore in fluid communication with a last portion of the pressure reducing portion and the outlet aperture, at least one intermediate portion interconnecting the first portion and the last portion, the portions of the pressure reducing portion being in fluid communication in series between the inlet receiver and the outlet bore to form a portion of an irrigation flow path, each portion of the pressure reducing portion including a first path portion and a second path portion, the first path portion having a first diameter and the second path portion having a second diameter, the second diameter being different than the first diameter to create a pressure loss when flowing through the pressure reducing portion, the bottom configured and arranged to operatively connect to the inner surface of the lateral wall.

An emitter for use with a lateral to form an irrigation lateral, the lateral including a lateral wall having an inner surface and an outlet aperture, comprising:

a base having a top, a bottom, a first end, a second end, a first side, and a second side, the base including a pressure reducing portion, the top including an inlet receiver in fluid communication with a first portion of the pressure reducing portion, the bottom including an outlet bore in fluid communication with a last portion of the pressure reducing portion and the outlet aperture, at least a first intermediate portion interconnecting the first portion and the last portion, the portions of the pressure reducing portion being in fluid communication in series between the inlet receiver and the outlet bore to form a portion of an irrigation flow path, the first intermediate portion including a first vertical path portion interconnecting a first top path portion and a first bottom path portion, the first vertical path portion having a first vertical diameter, the first top path portion having a first top diameter, the first bottom path portion having a first bottom diameter, the first vertical diameter being smaller than the first top diameter and smaller than the first bottom diameter to create a first pressure loss when flowing through the pressure reducing portion, the bottom configured and arranged to operatively connect to the inner surface of the lateral wall.

A combination emitter and lateral forming an irrigation lateral, comprising:

a lateral including a lateral wall having an inner surface and an outlet aperture;
an emitter having a base, the base having a top, a bottom, a first end, a second end, a first side, and a second side, the base including a pressure reducing portion, the top including an inlet receiver in fluid communication with a first portion of the pressure reducing portion, the bottom including an outlet bore in fluid communication with a last portion of the pressure reducing portion and the outlet aperture, at least one intermediate portion interconnecting the first portion and the last portion, the portions of the pressure reducing portion being in fluid communication in series between the inlet receiver and the outlet bore to form a portion of an irrigation flow path, each portion of the pressure reducing portion including a first path portion and a second path portion, the first path portion having a first diameter and the second path portion having a second diameter, the second diameter being different than the first diameter to create a pressure loss when flowing through the pressure reducing portion, the bottom configured and arranged to operatively connect to the inner surface of the lateral wall.
