ABSTRACT:
A purge control device for an evaporative control system comprises a single housing having two solenoid actuated valves controlling parallel orifices leading from an inlet chamber to an exit flow path. The two solenoid valves have different sized orifices to provide different flow capacities. Purge flow is controlled by an electronic control module which regulates the duty cycle of the solenoids. Each valve receives its own signal so that the flow through the orifices is individually controlled.
