We usually encounter piston compressors in small workshops as a producer of compressed air to clean dirt and fill motorcycle or car tires. The working principle is the same as the tire pump, which compresses the air in the cylinder with a piston. The difference lies in the valve, the two valves are mounted on the cylinder head, and the driving force is an electric motor. The air tank functions the same as tires, just like storage for compressed air energy. Apart from that, if you require a high-quality compressor for your garage, you can check them out on Garage Master Blog.

A piston compressor or reciprocating compressor is changing the reciprocating motion of the piston. This movement is obtained by using a crankshaft and a drive rod which produces an alternating motion on the piston. Its piston sucks air into the cylinder, then it compresses the air. The working steps of a piston compressor are almost the same as the working concept of a piston motor.

This compressor’s working principle consists of 3 steps, they are:

1. Suction Step

The crankshaft rotates, the piston moves from the top dead center to the bottom dead center. Vacuum occurs in the space in the cylinder so that the suction valve opens by the pressure difference and the air is sucked into the cylinder.

2. The Compression Step

The compression stroke occurs when the piston moves the lower dead center to the upper dead center, the inlet valve and the exit valve are closed so that the air is compressed in the cylinder.

3. Step Out

When the piston continues its movement to the top dead center, the pressure in the cylinder will increase so that the valve exits by the air pressure so that air exits into the air storage tank.

Double Acting Torque Compressor

The double-acting piston compressor works no differently from a single-acting. In double work, each movement occurs at the same time as a step of suction and compression. With double working, the compressor works more efficiently and more air is saved.
