Piston (Reciprocating) Air Compressors

Piston compressors are constructed similar to a combustion engine. The piston is a connecting rod and crankshaft, while it goes up and down in a cylinder. Valves control the air entering and discharging from the cylinder. As the piston moves downward, the intake valve opens and air to move into the cylinder. At the lower end of the piston travel, the inlet valve closes trapping the air in the cylinder. As the piston, it changes direction and returns to the top of the cylinder begins to compress the air. At the top of it stroke, exhaust valve opens and allows the compressed air leaving the cylinder.
