Abstract
A valve having a continuously adjustable flow rate which can be used in an insufflator. The valve includes an inlet fluidly coupled with a fluid supply, a chamber fluidly coupled with the inlet, a perforated disk, an outlet, and a two-sided dynamic seal arranged about the perforated disk and having a first side fluidly coupled with the chamber and a second side fluidly coupled with the outlet. By varying a rotational velocity (or frequency) of the perforated disk, the flow rate of the valve can be continuously adjusted.
