returns to the oil circuit via a separate line. The minimum pressure valve (Vp - see section Air flow)
ensures a minimal pressure in the tank, required for oil circulation under all circumstances.
The oil system is fitted with a by-pass valve (BV). When the oil temperature is below the set-point of the
valve, the by-pass valve shuts off the oil supply from oil cooler. The by-pass valve starts opening the
supply from cooler (Co) when the oil temperature exceeds the setting of the valve. The setting of the by-
pass valve depends on the model. See the section Compressor data.
