Reducing valve – located just before the filter. The valve will
open if the lubricating oil pressure is too high and will return
excess oil back to the sump.
Oil filter – of full-flow type, with a filter element of pleated filter
paper. To protect the engine against insufficient lubricating oil, a
by-pass valve is fitted in the oil filter bracket. The valve will open
if the lubricating oil pressure should rise above a certain pressure
due to clogging of the filter. When the valve is open, unfiltered oil
will flow to the engine. The filter is of disposable type and should
be scrapped after use.
By-pass filter – approx. 5% of the oil passes through the by-pass
filter with very low speed. The low speed allows very small parti-
cles to be separated. The filter insert is of the disposable type.
Crankcase ventilation - prevents over-pressure in the crank-
case and separates fuel mist, water mist and other gaseous com-
bustion products. The crankcase ventilation is controlled by a
pressure regulator which discharges excessive pressure from the
crankcase through a pipe connceted to the turbo-compressor
suction line. .
