FLOW CONTROL BY SUPERPOSITION OF INTEGRATED NON-LINEAR VALVES

FLOW CONTROL BY SUPERPOSITION OF INTEGRATED NON-LINEAR VALVES

A valve assembly using at least two pressure-sensitive leaky check valves has a non-linear flow-rate versus pressure-drop relation. A method for optimizing such a valve assembly is capable of determining a minimum required number of such valves and outputting the material parameters of each valve. T...

Zusammenfassung:A valve assembly using at least two pressure-sensitive leaky check valves has a non-linear flow-rate versus pressure-drop relation. A method for optimizing such a valve assembly is capable of determining a minimum required number of such valves and outputting the material parameters of each valve. The valve assembly and method allows for arbitrary flow control, which has numerous applications such as within drug delivery, food processing, and industrial flow control. The valve assembly is completely passive, i.e. there is no need for a feedback network. The flow control is achieved using only fluid-structure interactions.
