  • Pulse width modulated solenoid purge valve
    Patent number: 5649687
    Abstract: A pulse width modulated solenoid purge valve for an on board fuel vapor recovery system of an automotive vehicle is operated by a solenoid that has a pole piece and armature that are shaped to operate at high frequencies. More specifically, the pole piece and the armature have an air gap interface that is defined by a protrusion of one that always intrudes into a recess of the other by a substantial amount to reduce response time of the armature and permit operation of the solenoid at the high frequencies.
