DESCRIPTION
The
power
steering
unit
is a
torsion-
bar
type
of
hydraulic
assisted
system.
This
system
furnishes
power to
reduce
the
amount
of
turning
effort required
at
the
steering
wheel.
It also
reduces
road
shock
and
vibrations.
The
torsion
bar
power
steering
unit
includes
a
worm
and
one piece
rack
piston,
which
is
meshed to
the
gear
teeth
on
the
steering
sector
shaft. The
unit
also
includes a
hydraulic
valve,
valve
actuator,
and
torsion
bar as
sembly
which
are
mounted
on the
end
of
the
worm
shaft and
operated
by
the
twisting
action
of
the
torsion
bar.
The
torsion-bar
type
of
power
steer
ing
gear
is
designed
with
the
one
piece
rack-piston,
worm
and
sector
shaft
in
one
housing
and
the
valve
spool
in
an
attaching
housing
(Fig.
1).
This
makes
possible
internal
fluid
passages
between
the
valve
and
cylin
der,
thus
eliminating
all
external lines
and
hoses,
except
the
pressure and
return
hoses
between
the
pump
and
gear
assembly.
The
power
cylinder
is
an
integral
part
of
the
gear
housing.
The
piston is
double
acting,
in
that
