 Operation 

  

The oil is separated from the discharge gas in the oil separator. The oil then passes into the separator oil reservoir 

section. The oil reservoir section retains enough oil to supply the compressor oil/level regulators under all 

conditions. From the oil reservoir section the oil is supplied to the compressor where it is fed to the compresso 

through the capillary line.
