For damping force changeover, the
damping
force
chongeover actuator
is
operated by
a
signal
from
the
control
unit which causes the rotary valve bu
ill
into the pis
ton
rod to rotate and changes
the

The
rotary valve has large and
small
orifices
(1
each
for
a tota

cross sectionS A·A, B-B, C-C, and D-D

There is
also one passage {for

The
damping force is charJged
in
3 steps by combin

the rotary

and piston rod passages.
When
the ECS control unit confirms the change in
the damping

from
the
position detection switch,
it
