Abstract
A miniature quantum fluid transfer system configured to regulate the flow rate of a fluid by allowing passage of small, discrete increments of fluid through the valve including a valve body having at least one inlet to receive fluid and at least one outlet to release fluid, and a valve rod movably disposed in a first chamber in the valve body. The valve rod has a plurality of fluid passages spaced longitudinally along the valve rod, and the valve rod is movable to align each fluid passage with an inlet or outlet port in the first chamber to allow fluid to flow through selected inlet or outlet ports corresponding to selected fluid passages. The quantum fluid transfer system has a plug movably disposed in a second chamber to push a corresponding volume of fluid out of the second chamber at the end opposite the end the fluid entered.
