GENERAL DESCRIPTION
A pneumatic level control system that automatically
maintains correct rear trim height of a car under varying
load conditions, the optional automatic level control is
used only in conjunction with the Superlift Shock Absorber
option.
The Superlift Shock Absorber option alone, consists of
the two shock absorbers with pressure lines to a "Tee"
where a ill valve is located, the shocks are inflated
with (or deflated of) compressed air (at any gas station)
to obtain the vehicle level desired with any given load
change.
The automatic leveling system is added to the Superlift
Shock Absorbers and supplies its own compressed air.
The system (fig. 13) consists of a vacuum operated air
compressor with pressure regulator,
and
integral storage
tank, vacuum line to engine, air intake filter, air lines,
and a height control valve.
The COMPRESSOR is a two-stage, vacuum actuated
type, requiring no lubrication. Vacuum supply is taken
from engine carburetor base. High pressure air is
supplied to the reservoir tank by the second stage of
the two-stage compressor. The first stage intake stroke
draws air at atmospheric pressure through a oneway
check valve located in the end of the first stage housing
under the first ^tagei housing cover. On the first stage
compression stroke, the intake valve is closed and the
oneway check valve in the second stage end of the piston
is opened. This allows the air from the first stage
cylinder to flow through the hollow piston into the second
stage cylinder for jhigh pressure compression. The
second stage compression stroke closes the check valve
in the piston and opeijis the check valve in the end of the
second stage housing.
The intake and compression strokes are controlled by a
sliding distributor valive that is actuated through an arm
that is tripped by the piston as it nears the end of each
stroke. Each time the arm actuates the distributor
valve, a different set of holes are covered in the first
stage housing. The distributor valve controls the flow of
intake manifold vacuum and air under atmospheric pres-
