2.4.2 Air flow
Air drawn through the airfilter (AFce) into the compressor element (CEhp CElp) is compressed. At
the element outlet, compressed air and oil pass into the air receiver/oil separator (AR/OS).
The check valve (CV) prevents blow-back of compressed air when the compressor is stopped. In
the air receiver/oil separator (AR/OS), most of the oil is removed from the air/oil mixture.
The oil collects in the receiver and on the bottom of the separator element.
The air leaves the receiver via a minimum pressure valve (MPV) which prevents the receiver
pressure from dropping below the minimum working pressure, even when the air outlet valves are
open (specified in section 8.2.2 Limitations). This ensures adequate oil injection and prevents oil
consumption. The minimum pressure valve (MPV) also functions as a check valve.
The system comprises temperature sensors (TS), pressure sensors (PS) and a working pressure
sensor (WPS).
