THERMOSTAT

A

pellet
type
thermostat
is

used
in
the
wa

ter

passage
to

control
the
flow
of
coolant

providing
fast

regulating
coolant

temperature
A

wax

pellet
in
the

thermostat

expands
when

heated
and

contracts
when

cooled
The

pellet
is
connected

through
a

piston
to
a
valve

and
when
the

peUet
is
heated

pressure
is

exerted

against
a
rubber

diaphragm
and
the
valve

opens

As
the

pellet
is

cooled
the

allows
the
