System and method for providing an adjustable flow rate

An adjustable flow system comprising:

• a first pathway for directing fluid from a fluid reservoir;
• an adjustable flow resistor having its input end in communication with the first pathway for receiving a flow of fluid from the fluid reservoir, the adjustable flow resistor including:
• a flow chamber;
• a flow modifier disposed within the flow chamber, the flow modifier configured to define a flow channel between the flow modifier and an inner surface of the flow chamber, the flow channel having one or more flow channel property, the flow modifier configured to move within the flow chamber and modify a flow channel property in response to a pressure of the flow of fluid acting on the flow modifier;
• a resistance member disposed within the adjustable flow resistor and configured to apply a force on the flow modifier, the resistance member having one or more resistance member property configured to affect movement of the flow modifier;
• and
• an adjustment mechanism configured to adjust a resistance member property and controllably modify a constant flow rate of the fluid flow exiting the adjustable flow resister;
• and
• a second pathway in communication with an output end of the adjustable flow resistor to direct fluid exiting the adjustable flow resistor.
