Air Compressor
The air compressor is a positive displacement air pump, powered by a
12-volt DC permanent-magnet motor. The air compressor head contains intake
and exhaust ports plus a solenoid-operated exhaust valve that releases air
from the ALC system when energized. Air compressor intake air is drawn through
an intake air hose and filter, mounted in the right side body rail. The air
compressor is a serviceable part and is mounted on a bracket. The bracket
is mounted to the underbody, right side, in front of the rear suspension.
Air Dryer
The air dryer is attached to the air compressor head assembly at the
pressure outlet and provides a dual function:
• | It contains a moisture-absorbing chemical (desiccant) that absorbs
moisture from the compressed air before it is delivered to the rear shocks.
Moisture is removed from the air dryer and returned to the atmosphere when
air is exhausted out of the shocks during lowering. |
• | It contains valving that maintains a system pressure (residual
pressure) of 48-97 kPa (7-14 psi). This system pressure
is maintained for improved ride characteristics and improved air sleeve reliability. |
Exhaust Solenoid
The exhaust solenoid is a non-serviceable part of the air compressor
head and provides a dual function:
• | When energized, it exhausts air from the rear shocks. |
• | It acts as a relief valve to limit the maximum air pressure output
of the compressor. |
