Pneumatic is what is related to air or to machines operated by compressed air. It also concerns the functioning of the lung.
THE pneumatics is the science that studies the mechanical systems of air compression.
Comes from the Latin term pneuma, which means breath of air. It originated several Portuguese words related to respiratory function, such as pneumonia and pneumatology.
O pneumatic bone it is so called because it has cavities that allow air to pass through, such as the frontal bones and temporal bones in humans. In birds, pneumatic bones are related to flight activity.
In the book Admirable new world, by Aldous Huxley, the author uses the word "pneumatic" as an adjective for curvaceous women.
Pneumatic System
The pneumatic system works by compressing gases, which they convert into mechanical energy, moving pistons and shafts.
Pneumatic machines are part of industrial production and even transport systems such as a pneumatic truck brake.
They are also medical tools, as in the case of the pneumatic tourniquet, surgical equipment to block blood circulation.
Pneumatic tools, such as the pneumatic nailer or pneumatic screwdriver, are fundamental for industrial automation, performing repetitive motion work on the assembly line.
O pneumatic muscle it is also an industrial device, and its functioning is based on human anatomy. It expands or contracts, depending on pressurization, and is used to compose complex mechanical systems.
Hydraulics and Pneumatics
Hydraulic and pneumatic systems work in a similar way. While pneumatics creates mechanical systems based on compressed air, hydraulics generate energy through the passage of fluids, the most common being water.
The difference in the operation of hydraulics and pneumatics is also due to the reuse of materials. The air used by pneumatic machines is expelled after fulfilling its function, without being used again. On the other hand, in hydraulic machines, the discarded liquids can return to the mechanical system.
Tire and Tire
The words tire and pneumatic are synonymous. The term tire is a reduction of tyre, and both can be used in the same sense.
At the end of the 19th century, the French company Michelin registered the word pneumatic to designate the rim that surrounds the vehicle wheel, as we know the tire today, creating then the term that was incorporated in other languages, with small changes.
