ABSTRACT:
A variable area reed flow restrictor is presented in which a flexible reed spring is attached at one end to a plate having a shaped flow orifice and extends over the orifice. A fulcrum bar is connected to the plate to define a fulcrum about which the free end of the reed flexes. The fulcrum can be positioned to achieve a linear relationship between flow and pressure drop across the orifice.
