If only one side of the piston is used for compression, it is described as single-acting. [2] Creux invented the compressor as a rotary steam engine concept, but the metal casting technology of the period was not sufficiently advanced to construct a working prototype, since a scroll compressor demands very tight tolerances to function effectively. Model XASS from Atlas Copco circa 1985. Even though they are for intermittent air operation, their working principle differs. The back and forth moving membrane is driven by a rod and a crankshaft mechanism. A reciprocating compressor works in the following way: When the switch is on, the electric motor begins to turn, and the shaft connected to the piston rotates. 19 hours ago · Piston Type: This is a common compressor type that compresses gas through the reciprocating motion of a piston inside the cylinder. This also means that the compressed air that comes from the compressor contains oil residue, typically 10 to 15 mg/m³.
