The first patent for the pneumatic cylinder was issued in 1940 in the US to Samuel Clegg and Jacob Selvan. Alfred Beach was given a patent in 1865 for a pneumatic subway train using a giant pneumatic tube.
Hydraulic cylinder use a liquid medium, often some type of viscous oil, in the cylinders and can be subject to higher pressures then pneumatic cylinders which use air or some other gas and work under a lower pressure.
A pneumatic pipe is a type of tubing or conduit used to transport compressed air or gases in pneumatic systems. These pipes are designed to withstand high pressure and are typically made from materials such as plastic, rubber, or metal. Pneumatic pipes are commonly used in various applications, including industrial automation, machinery, and tools, where they facilitate the movement of air to power actuators, cylinders, and other components. Proper selection and maintenance of pneumatic pipes are essential for system efficiency and safety.
Simple electro-pneumatic devices include pneumatic cylinders that are controlled by solenoid valves, allowing for linear motion in automated systems. Another example is pneumatic grippers, which use compressed air to grasp and manipulate objects. Additionally, pressure regulators that adjust air pressure in a system based on electrical signals demonstrate electro-pneumatic functionality. These devices are commonly used in manufacturing and assembly processes for efficient automation.
Hydraulic cylinders will be linked to the bath at both ends, as the oil needs to remain pressurised to work effectively.Pneumatic cylinders have springs if they're single way cylinders, as generally they can't rely on gravity to revert back to the first stage - dual cylinders on the other hand have 2 springs so they can switch sides.That aside, the hissing from Pneumatics should just about give it away.
Pneumatics are widely used in various applications, such as in industrial automation where pneumatic cylinders power machinery for tasks like assembly and packaging. In the automotive industry, pneumatic systems are employed in air brakes for trucks and buses, providing reliable stopping power. Additionally, tools like pneumatic drills and wrenches use compressed air for efficient operation in construction and maintenance tasks. Lastly, pneumatic tubes are utilized in banks and hospitals for transporting documents and small items swiftly.
Hydraulic cylinder use a liquid medium, often some type of viscous oil, in the cylinders and can be subject to higher pressures then pneumatic cylinders which use air or some other gas and work under a lower pressure.
To create a Lego pneumatic suspension, you'll need pneumatic components such as pumps, cylinders, and tubing. Begin by connecting the pneumatic cylinders to a base and attaching them to the Lego chassis to serve as the suspension. Use a pump to control air pressure, allowing the cylinders to expand and contract, simulating a suspension system. Finally, fine-tune the setup by adjusting the air pressure for optimal performance.

Companies in the fluid power cylinders and actuators industry manufacture hydraulic and pneumatic cylinders used in various devices, such as jacks, lifters, and machine tools.
John Dunlop invented the pneumatic tubes.
Working fluid. In one it's gas (air) and in the other it's liquid. This is a much bigger difference than it might seem at first, because gases are compressible and liquids, to a very good approximation, are not.

In 1650, Guericke invented the first air pump. It could produce a partial vacuum and Guericke used it to study the phenomenon of vacuum and the role of air in combustion and respiration. The best known pneumatic device is of course the pneumatic tube. A pneumatic tube is a method of transporting objects using compressed air. In the past, pneumatic tube was often used in large office buildings to transport messages and objects from office to office. In 1829, the first stage or compound air compressor was patented. A compound air compresor comprases air in successive cylinders. The hand bellows used by early smelters and blacksmiths for working iron and metals was a simple type of air compressor and the first pneumatic tool.
In 1895, André Michelin was the first person to use pneumatic tires. those make the ride smoother.
Pneumatic systems use compressed air to perform work, often in industrial applications such as powering tools, actuating cylinders, and controlling valves. To use a pneumatic system, you first compress air using a compressor, then store it in a reservoir. The stored air can be directed through pipes to various devices, like pneumatic cylinders or motors, which convert the air pressure into mechanical motion. Proper maintenance and safety measures are crucial to ensure efficient operation and prevent accidents.
A pneumatic drill, powered by compressed air, is mainly used to drill rock and break up pavement. However, it is not clear exactly who invented it. Some sources point to Samuel Ingersoll in 1871; others state that he invented the pneumatic hammer instead, an achievement more commonly associated with the aforementioned King.
