Evaporative solenoid control valve with enhanced durability features |
摘要 |
An evaporative solenoid valve assembly for use in a vehicle fuel system between a filtration canister and an intake manifold includes a plunger having a plunger body with central-bore and an elastomeric insert molded therein to define a stop cushion at the end of the insert proximal the valve stop and a valve tip at the end of the insert proximal the valve seat. The valve assembly may include a valve stop having a non-conducting insert received in an end proximal the plunger to reduce noise and wear as well as to improve magnetic flux path. Yet another improvement includes an enlarged pre-load spring disposed within the plunger to provide better spring force distribution and plunger to valve seat alignment.
