Operator’s <strong>Manual</strong><br />
When the piston moves into the cylinder, the pressure rises in the cylinder. At the same time however, the temperature of the enclosed<br />
gas also rises. This is a basic physical law (Gay--Lussac).<br />
Since with increasing pressure, the occuring temperatures would soon reach inadmissibly high values, the compression has to be<br />
divided into various stages. After every stage the gas is cooled back to approx. 10 -- 15 °C above ambient temperature. This is the<br />
main reason for designing compressors with 3 or 4 stages.
