The oil system is provided with a thermostatic bypass valve (BV). When the oil temperature is
below 40 ˚C (104 ˚F), the bypass valve shuts off the oil supply from oil cooler (Co). Air pressure
forces the oil from air receiver (AR) through oil filter (OF) and oil stop valve (Vs) to compressor
element (E). Oil cooler (Co) is bypassed. When the oil temperature has increased to 40 ˚C (104
˚F), bypass valve (BV) starts opening the supply from oil cooler (Co). At approx. 55 ˚C (131 ˚F),
all the oil flows through the oil cooler.
