ABSTRACT:
A flow control device having no moving parts that controls fluid flow along a fluid pathway in such a way that flow rate remains constant irregardless of environmental changes. The device achieves a constant flow rate by taking advantage of the properties of the fluid moving along the fluid pathway and maintains the constant flow rate irregardless of changes in viscosity due to changes in temperature.
