Patent ID: 8333330

Claim:
A dual-path fluid routing system, comprising: a first path in fluid communication with a fluid source and an output node, said first path comprising: a first regulator connected to said fluid source and having a first regulator output; and a heat exchanger connected to said first regulator and said output node, said heat exchanger operative to change the temperature of fluid flowing through said first path; a second path in fluid communication with said fluid source and said output node, said second path comprising: a second regulator connected to said fluid source and having a second regulator output; and a flow restriction device connected to said second regulator output and said output node and operative to restrict mass flow through said second path, said flow restriction device restricting flow to a degree sufficient to decouple said first regulator output and said second regulator output, thereby enabling said second path to inject a desired quantity of said fluid into said first path; and control circuitry operative to control said first and second regulators to provide a fluid of a predetermined pressure and temperature to said output node, said predetermined pressure variable between 0 and 1,000 PSI.
