When in operation, the oil pump draws the oil from the oil tank through the thermostat to
the oil radiator and forces it through the oil filter to the lubrication points. From here the
engine oil is distributed to all lubrication points and flows from there back into the oil tank,
driven by piston blow-by gases.
When installed, the thermostat bypasses the radiator when the oil temperature are below
the normal operating temperature range.
In case of the oil filter mat clogging, an emergency pressure valve will open and unfiltered
lube oil will flow to lubrication points.
