Abstract: Methods and apparatuses for providing an adjustable flow resistor. The adjustable flow resistor can include a chamber into which fluid is introduced, having an input end and an output end. A flow modifier can be situated within the chamber, between the input end and the output end, to modify a flow rate of the fluid. An adjustable resistance member can be positioned to interact with the flow modifier within the chamber to controllably modify the constant flow rate out of the adjustable flow resistor.
