Air drawn through the airfilter (AF
CE
) into the compressor element
(CE) 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 remaining oil is
removed by the separator element.
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 (specified in section
1.3
), even when the air outlet
valves are open. This ensures adequate oil injection and prevents oil
consumption.
A temperature switch (TS) and a working pressure gauge (PG) are
comprised in the system.
A blow-down valve (BDV) is fitted in the unloader assembly to
automatically depressurise the air receiver (AR) when the compressor
is stopped.
