Abstract
Abstract A family of aerating liquid discharge nozzles, each of which has the feature that it contains no moving parts and includes a hollow body defining a liquid inlet at one end and an outlet opening at the other end at opposite ends of an internal duct through the body. A plug, having substantial length between opposite end surfaces relative to the diameter of the duct, is disposed across the duct and is secured from movement along the length of the body. Liquid flow passage means are defined through the plug by a plurality of grooves formed in the side walls of the plug communicating between opposite ends of the plug. A discharge modulating member has opposing closed end end surfaces, one of which is coupled to the plug coaxially thereof and has a maximum transverse extent no greater than the minimum transverse extent of the adjacent end of the plug between opposed grooves in the plug side walls. By varying the configuration and/or position of the modulating member, a wide variety of discharge patterns may be produced.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
149 words
An aerating liquid discharge nozzle comprising: a. an elongate body having opposite open ends defining a duct therethrough between a liquid inlet opening defined at one open end of the body and a liquid outlet opening defined at the other open end of the body; b. a plug disposed across the duct adjacent the outlet opening and secured from movement along the length of the body; c. a plurality of liquid flow passages defined through the plug proximate the periphery of the plug and communicating between the opposite ends of the plug; and d. a discharge modulating member disposed coaxially of the plug and coupled to the end of the plug adjacent the liquid outlet opening, the modulating member having a smooth circumferential surface extending between opposite ends thereof and having a maximum transverse extent at the end thereof adjacent the plug insufficient to close any of the passages.
Claim 2
Dependent Claim
149 words
An aerating liquid discharge nozzle comprising: a. an elongate body having opposite open ends defining a duct therethrough between a liquid inlet opening defined at one open end of the body and a liquid outlet opening defined at the other open end of the body; b. a plug disposed across the duct adjacent the outlet opening and secured from movement along the length of the body; c. a plurality of liquid flow passages defined through the plug proximate the periphery of the plug and communicating between the opposite ends of the plug; and d. a discharge modulating member disposed coaxially of the plug and coupled to the end of the plug adjacent the liquid outlet opening, the modulating member having a smooth circumferential surface extending between opposite ends thereof and having a maximum transverse extent at the end thereof adjacent the plug insufficient to close any of the passages.
Claim 3
Dependent Claim
16 words
The nozzle of claim 1, wherein the modulating member abuts the one end of the plug.
Claim 4
Dependent Claim
21 words
The nozzle of claim 1, wherein the modulating member has an end surface opposite from the plug situated within the duct.
Claim 5
Dependent Claim
21 words
The nozzle of claim 1, wherein the modulating member has an end surface opposite from the plug situated without the duct.
Claim 6
Dependent Claim
13 words
The nozzle of claim 1, wherein the modulating member is of cylindrical configuration.
Claim 7
Dependent Claim
14 words
The nozzle of claim 1, wherein the modulating member is of right-circularly cylindrical configuration.
Claim 8
Dependent Claim
14 words
The nozzle of claim 1, wherein the modulating member is of truncated conical configuration.
Claim 9
Dependent Claim
19 words
The nozzle of claim 1, further comprising a liquid outlet channel defined through both the plug and modulating member.
Claim 10
Dependent Claim
28 words
The nozzle of claim 3, wherein the opposite end surface of the modulating member is disposed substantially in the plane of the liquid outlet opening from the body.
Claim 11
Dependent Claim
20 words
The nozzle of claim 7, wherein the smaller diameter end surface of the modulating member is coupled to the plug.
Claim 12
Dependent Claim
20 words
The nozzle of claim 7, wherein the larger diameter end surface of the modulating member is coupled to the plug.
Claim 13
Dependent Claim
26 words
The nozzle of claim 8, further comprising means coupling the modulating member to the plug, the liquid Outlet channel being defined through said means coaxially thereof.
Claim 14
Dependent Claim
153 words
An aerating liquid discharge nozzle comprising: a. an elongate body having opposite open ends defining a duct therethrough between a liquid inlet opening defined at one open end of the body and a liquid outlet opening defined at the other open end of the body; b. a plug disposed across the duct adjacent the outlet opening and secured from movement along the length of the body; c. a plurality of liquid flow passages defined through the plug proximate the periphery of the plug and communicating between the opposite ends of the plug; and d. a discharge modulating member disposed coaxially of the plug and coupled to the end of the plug adjacent the liquid outlet opening, the modulating member having a maximum transverse extent at the end thereof adjacent the plug insufficient to close any of the passages and having a circular transverse cross-sectional configuration at any location therealong coaxially of the plug.
