Patent ID: 6871674

Claim:
An apparatus for creating a use solution of a first product diluted, with a dilution rate of not more than 1:130, and a second product diluted, with a dilution rate of more than 1:130, into a diluent flowing under pressure in a line, comprising: a normally-closed, user activatable valve operatively coupled in said line allowing said second product to flow in said line upon user activation; a flow regulator, operatively coupled in said line downstream of said valve, configured to maintain a constant flow rate for said diluent in said line; an aspirator adapted to be fluidly coupled to said second product and operatively coupled in said line downstream of said flow regulator; and a constant flow rate pump having an inlet and an outlet and being operatively coupled to said valve, said inlet adapted to be operatively fluidly coupled to said first product and said outlet fluidly coupled to said line downstream of said flow regulator.
