The removable purge valve assembly incorporates the
purge valve mechanism and a turbocharger cut-off feature
that is designed to prevent loss of engine "turbo" boost
pressure during the purge cycle of the Bendix
dryer and reservoir system. For ease of maintenance, all
replaceable assemblies can be serviced without removal
of the air dryer and reservoir system from its mounting on
the vehicle. Refer to Preventive Maintenance section.
