INTAKE
ACTUATOR

The

is

actuated

by

the

intake
vacuum
or
the

atmospheric

air
introduced

by
turning
on
or
off
the

vacuum
switch

thereby
opening

closing
the

door
The
intake

port
for

atmospheric
air
is

located
on

the
vacuum

switch

The

check
valve

is

a
one

way
valve

and
it

prevents

negative
pressure
from

passing
through
it

except
when
the

pressure
at
the
actuator
side
is

higher

than
at
the

intake
manifold
side

thus

eliminating
the

in
