<p>In a fluid flow restrictor (400), the amount of fluid flow restriction increases in ersponse to higher dispensing system pressures and decreases in response to lower dispensing system pressures. In this manner, a relatively consistent flow rate of fluid (16) being dispensed can be maintained regardless of fluctuations in system pressure. Variable resistance is provided by changing the length of the fluid flow path or by changing the cross-sectional area, and, thus, the volume of the fluid flow path, or by changing both the length and the cross-sectional area of the fluid flow path.</p> |
