Abstract
Abstract The invention disclosed herein describes a mixing apparatus for mixing a second liquid with a first liquid. The mixing apparatus includes a housing having a bushing located therein, the bushing functioning as an eductor means for entraining the second liquid into the first liquid. A pair of axial grooves are defined on the outer surface of the bushing to permit a portion of the first liquid to be bypassed past the eductor means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
175 words
A mixing apparatus for mixing a second liquid with a first liquid comprising: a sprayer having an inlet and an outlet with a cylindrical chamber being located therebetween, the inlet of the sprayer being connected to a source of the first liquid; an eductor having a housing disposed within the sprayer chamber and including an inlet passage being connected to the sprayer inlet, an aspiration chamber, and a diffusion passage connected in series; first conduit means for connecting the aspiration chamber to the second liquid; at lease one axial groove formed on the outer surface of said eductor housing and being connected to said sprayer inlet for bypassing a portion of the first liquid past the aspiraTion chamber; and mixing chamber means located between the eductor and the sprayer outlet for connecting the bypass conduit means and the diffusion passage with the sprayer outlet, each of said axial grooves being of a constant cross section over its entire length to create a laminar flow therethrough and to prevent creating any additional suction on the eductor.
Claim 2
Dependent Claim
175 words
A mixing apparatus for mixing a second liquid with a first liquid comprising: a sprayer having an inlet and an outlet with a cylindrical chamber being located therebetween, the inlet of the sprayer being connected to a source of the first liquid; an eductor having a housing disposed within the sprayer chamber and including an inlet passage being connected to the sprayer inlet, an aspiration chamber, and a diffusion passage connected in series; first conduit means for connecting the aspiration chamber to the second liquid; at lease one axial groove formed on the outer surface of said eductor housing and being connected to said sprayer inlet for bypassing a portion of the first liquid past the aspiraTion chamber; and mixing chamber means located between the eductor and the sprayer outlet for connecting the bypass conduit means and the diffusion passage with the sprayer outlet, each of said axial grooves being of a constant cross section over its entire length to create a laminar flow therethrough and to prevent creating any additional suction on the eductor.
Claim 3
Dependent Claim
33 words
The combination as defined in claim 1 wherein the eductor is formed by a bushing disposed within the cylindrical sprayer chamber with the inlet passage, aspiration chamber, and diffusion passage being formed therein.
Claim 4
Dependent Claim
28 words
The combination as defined in claim 2 wherein the axial grooves are defined by a pair of axial grooves formed diametrically on the outer surface of the eductor.
Claim 5
Dependent Claim
59 words
The combination as defined in claim 2 wherein the eductor is formed by an outer bushing, having the inlet passage and an enlarged cylindrical passage adjacently formed therein, and an inner bushing having the diffusion passage formed therein being located within the cylindrical passage, with the space between the inlet passage and the inner bushing defining the aspiration chamber.
Claim 6
Dependent Claim
44 words
The combination as defined in claim 2 wherein a choke cartridge having a discharge passage formed therein defining the sprayer outlet, the choke cartridge being disposed within the sprayer chamber with the space between the eductor and the choke cartridge defining the mixing chamber.
