Technical description
Lubricating unit
Cooling pipes (Fig. 14)
The cooling pipes between the 1
st
and 2
nd
stage,
between the 2
nd
and 3
rd
stage and after the 3
rd
stage
are made of stainless steel, like those for the
passage of air between the separator and the filter.
This valve is fitted after the final filter. Just a few seconds after the compressor has been started up, it
keeps the pressure of the entire system at 100 ± 20 bar (see exploded view Chapter 14), for the purpose
of eliminating as much water as possible from the air. It also acts as a non-return valve.
Pressure maintenance valve
Lubrication is carried out by means of a tang
screwed into the end part of the connecting rods
of the 2
nd
and 3
rd
stages (Fig. 13).
The 3
rd
high pressure stage is lubricated by oil
vapours.
