Abstract

A fluid flow control device autonomously chokes the fluid flow from a first volume to a second volume to achieve a predetermined fluid flow rate for a range of expected differential pressures across the device, for example a device where the valve chokes the fluid flow to the same flow rate for any differential pressure (within a range of expected differential pressures) across the device. The device has a piston arranged in a housing. At an end of the piston is a constriction body that creates an annular opening in a flow passageway of the device. A pressure dependent upon the first volume is established in a pressure chamber and biases the constriction member from a relatively open position to relatively closed position against the force of a spring and the pressure of the second volume. The shape of the constriction body is configured to create annular openings of predetermined sizes at specific differential pressures in order to create a predetermined flow rate profile.
