Abstract
An improved regulator valve for controlling the purging of fuel vapors collected in a canister and an evaporative emission control system into an intake system of an internal combustion engine employs a solenoid valve assembly with an armature disposed outside of the coil to operate with low friction. A spring separating the armature from the valve member allows the spring to absorb most of the magnetic and gravitational side loading.
