The principle behind working of hydraulic and pneumatic devices

Pneumatic devices

Pneumatic machines are machines that apply heavy-duty force towards designated objects. Compressed air powers this force, by increasing or decreasing pressure within a closed area. They’re usually used in the manufacturing industry to make the items that we need in our daily lives.

Pneumatics is the use of compressed air to generate work in a device or process. They are often implemented when mechanical energy is not sufficient. By “mechanical” we refer to human labor. It can be as simple as pulling a.... View More
