  • Control system for providing dual vacuum levels
    Patent number: 5810329
    Abstract: A solenoid-type control system is disclosed, particularly for operating the locking hubs of a four-wheel drive vehicle. A solenoid valve assembly or mechanism has a coil member, a tubular member for directing air flow, and a valve mechanism at one end of the tubular member. A control circuit determines the level of energizing signal to the coil member which in turn controls the valve mechanism and the air flow passing through the tubular member. A switch mechanism has a moveable terminal which is operated by the level of energizing electrical signal.
