A reciprocating compressor is a positive displacement machine that increases the pressure of a gas by reducing its volume. It operates through the back-and-forth motion of a piston within a cylinder, similar to the way an internal combustion engine functions.

These compressors are widely used in industries such as oil and gas, refrigeration, and manufacturing. They are particularly suited for applications requiring high pressure at relatively low flow rates.

A typical reciprocating compressor consists of a crankshaft, connecting rod, piston, cylinder, and valves. As the piston moves downward, it draws gas into the cylinder through an intake valve. When it moves upward, the gas is compressed and discharged through the outlet valve.

Regular maintenance—such as checking lubrication, valve condition, and pressure balance—is essential for ensuring efficient operation and long equipment life.

How Does a Compressed Air Car Actually Work?

A compressed air vehicle (CAV) is powered by a simple yet clever principle: stored energy in the form of highly pressurized air. The core components are a carbon-fiber tank storing air at around 300 bar (4,350 psi) and a pneumatic engine, which functions similarly to a traditional internal combustion engine but uses expanding air instead of combusting fuel.

To "refuel," the vehicle is connected to a high-pressure air compressor, which refills the tank in a matter of minutes. When driving, the compressed air is released into the engine's cylinders. As the air expands, it pushes the pistons, creating rotational force to turn the wheels. The only exhaust is cold, clean air, which can even be used for air conditioning inside the cabin.
