ABSTRACT:
A fluid flow control device for maintaining a substantially constant predetermined rate of flow through a control valve including a fluid flow passage for directing fluid flow through the valve, a resilient fluid flow rate control washer positioned in the fluid flow passage for maintaining a substantially constant predetermined rate of flow through an outlet of the fluid flow passage irrespective of a pressure of the fluid in the passage and fluid flow conditioning washers for conditioning the flow of fluid through the flow rate control washer with the fluid flow conditioning washers being movable with respect to the flow rate control washer for aiding in the conformability of the flow rate control washer. Preferably, at least two fluid flow conditioning washers are positioned upstream of the flow rate control washer and at least one fluid flow conditioning washer is positioned downstream of the flow rate control washer.
