The piston rod is hollow.
When the piston goes
up
and down,
the coolant (oil)
enters through the piston rod bore and leaves through the
inside return line.

The piston is cooled by oil.
The advantages of oil as
a
coolant are:
. it reduces noise;
. it purifies;
. it forms a seal;
. it lubricates;
. it is anti-corrosive;
. it has a higher resistance
to heat.
