| Air compression is achieved by the interaction
of a fixed and an orbiting scroll. Air at inlet pressure enters the compression
chamber at the exterior side of the scroll element. Once air is drawn in,
the orbiting scroll seals off the inlet port. As the scroll continues to
orbit, the air is progressively compressed into an increasingly smaller
"pocket".
A continuous flow of compressed air leaves the scroll element through
a discharge port in the centre of the fixed scroll. This process is continuously
repeated, resulting in the delivery of pulse-free compressed air. |
