Oil filter, relief valve
Engine oil being fed from the
oil
pump
is
filtered
through the filter element and then supplied to the
related parts.
A
relief valve
is
provided just before
the
oil
filter
in
order to maintain the oil at a constant
pressure and to let excessive oil flow into
the
oil pan.
The
oil
comes into the filter element through
its
outer surface and out
of
its
inner surface.
A bypass valve
is
provided inside the filter. When
the element gets dirty and the
oil
starts flowing
against a resistance of
1
kgf
/
cm2 or higher, the oil
does not flow thorugh the element, but through
this
bypass valve.

The oil pressure
switch
is
mounted on the cylinder-
block, to warn the operator that
the
lubricating oil
pressure
is
poor.
If
the
oil
pressure falls below
49
kPa
(0.5
kgflcmz,
7
psi), the oil warning lamp
will
light up, warning
the
operator.
In
this
case, stop the engine immediately
and check the cause of pressure drop.
