Piston Air Compressor

A reciprocating air flow compressor is a positive displacement compressor that runs on the crankshaft-driven piston and cylinder to compress the air. … A two-stage compressor includes an additional step where in fact the air flow is compressed by a second, smaller sized piston to a pressure as high as 175 PSI.

Like a Piston Air Compressor little internal combustion engine, a typical piston compressor includes a crankshaft, a connecting rod and piston, a cylinder and a valve head. … As the piston movements down, a vacuum is established above it. This allows outside atmosphere at atmospheric pressure to push open the inlet valve and fill the region above the piston.
