Abstract
A vapor impermeable solenoid includes an outer housing fabricated from a vapor impermeable material configured to prevent fuel vapor molecules from passing therethrough; windings configured to generate a magnetic flux when energized, a flux collector configured to direct the magnetic flux, a pole piece, and a magnetic armature disposed within the housing and coupled to a seal configured to selectively seal a passage that allows fuel vapor to pass to a purge canister. The magnetic armature is configured to move from a first position to a second position when an electric current is applied to the windings.
