ABSTRACT:
A variable area valve and pressure regulator for providing fuel vapor purge control in an evaporative emission control system of an automotive vehicle. A solenoid valve assembly selectively controls fluid communication between a fuel vapor source and an intake manifold by varying the area of an orifice associated with the solenoid valve assembly. A pressure regulator assembly is responsive to pressure differentials between an inlet cavity and an outlet cavity to further control the flow through the purge regulator. In operation, the purge regulator assembly is operable to generate nonlinear output flow characteristics which are independent of changes in the intake manifold vacuum, as well as the inlet pressure, and which further provides the desired nonlinear response.
