Abstract
Abstract A mixing apparatus and system therefor is disclosed in which two fluid materials are mixed or blended in which the components may vary in viscosity from 1 to 100,000 centipoise. Basically a material which is desired to be emulsified or blended is fed from a source under pressure to a mixing chamber where it is forced through an orifice between the face of an elastomeric plug and its seat and delivered into a turbulent area where the other material is being passed effectively around the periphery of the plug in a turbulent pathway. There is violent agitation caused by the contact between the two materials, one coming at a high velocity from an orifice action coupled to the breaking up of the materials through the turbulent action that produces excellent emulsification for mixing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
142 words
In combination a pump, said pump having an inlet connected to a supply of a first liquid material, a mixing chamber, a supply of a second liquid vehicle material connected to said chamber, the output of said pump connected to said mixing chamber, an elastomeric plug retained in said chamber, said plug having a solid wall, means including an inlet leading into said chamber, a seat about said inlet, said plug wall being urged against said seat, the pressure developed by said pump forcing the plug away from the seat to create an orifice whereby the first material is passed through said orifice into said chamber, said second material being passed into said chamber, discontinuities in the wall of said chamber substantially at right angles to the second material flow which creates turbulence, and a receiver for the output of said mixer.
Claim 2
Dependent Claim
142 words
In combination a pump, said pump having an inlet connected to a supply of a first liquid material, a mixing chamber, a supply of a second liquid vehicle material connected to said chamber, the output of said pump connected to said mixing chamber, an elastomeric plug retained in said chamber, said plug having a solid wall, means including an inlet leading into said chamber, a seat about said inlet, said plug wall being urged against said seat, the pressure developed by said pump forcing the plug away from the seat to create an orifice whereby the first material is passed through said orifice into said chamber, said second material being passed into said chamber, discontinuities in the wall of said chamber substantially at right angles to the second material flow which creates turbulence, and a receiver for the output of said mixer.
Claim 3
Dependent Claim
78 words
A mixing chamber defined by a substantially cylindrical body wall, upper and lower end walls, two inlets and an outlet leading into said chamber, one inlet extending through an end wall and another inlet extending through the cylindrical wall, an elastomeric element urged against said end wall to normally close said one inlet, said cylindrical wall having turbulence producing flutes therein, said element being adapted to be displaced from said one inlet by pressure to create an orifice.
Claim 4
Dependent Claim
78 words
A mixing chamber defined by a substantially cylindrical body wall, upper and lower end walls, two inlets and an outlet leading into said chamber, one inlet extending through an end wall and another inlet extending through the cylindrical wall, an elastomeric element urged against said end wall to normally close said one inlet, said cylindrical wall having turbulence producing flutes therein, said element being adapted to be displaced from said one inlet by pressure to create an orifice.
Claim 5
Dependent Claim
15 words
A mixing chamber as in claim 2 wherein the elastomeric element is a solid plug.
Claim 6
Dependent Claim
17 words
A mixing chamber as in claim 2 wherein the elastomeric element is a mechanically spring loaded member.
