DESCRIPTION

Model
CF206
is
a
crank

type

compressor
specially
designed
with

minimum
size
and

light
weight
for

use

on

compact
vehicles

The

compressor
crankshaft
is

driven

by
a
belt
from
the
crankshaft

pulley

through
the

electromagnetic
clutch

Two

pistons
positioned
in

line
are

actuated

by
connecting
rods
coo

nected
to
the
crankshaft

Discharge
and
suction
valves
are

mounted
in
the

valve
liner
between
the

crankcase
and

cylinder
head

As
a
lubricant

SUNlSO
NO
5
is

used

Simplified
positive
pressure

lubrication
utilizes

existing
pressure

differential
between
suction

intake

and
crankcase
to

provide
a
film
of

lubricating
oil
to

bearings
All
internal

components
have
been

designed
to

provide
more
than

adequate
lubrica

tion
to

cylinder
walls

connecting
rod

bearings
and
seal

assembly
The
result

is

improved
lubrication
lower

seal

temperatures
reduced
oil

pumping

and
a

reduction
in
the
number

of

moving
parts
