Valves present inside the Pneumatic fittings and hydraulic cylinder help regulate the flow of compressed air or fluids and maintain the pressure inside the pressure inside the Pneumatic fittings or hydraulic cylinder. Some Pneumatic fittings cylinders reach 1000 mm in diameter, and are used in place of hydraulic cylinders for special circumstances where leaking hydraulic oil could impose an extreme hazard. Pneumatic fittings and hydraulic cylinders also find application in automated shutters in train and tram doors, and automated exits that are monitored and activated by sensors. The low friction nature of arrangement in Quick couplings and hydraulic cylinders enable a smooth, slow-speed operation and at a low pressure which is a safety consideration in human traffic areas. Run flat tires are the pneumatic vehicle tires. This tire is specifically crafted to resist the consequences of deflation when it gets punctured. This tire enables the vehicle to keep on moving at the reduced speed of 55 miles per hour and only for a limited distance up to maximum 200 miles. Such performance depends on the type of the run flat tire. The basic principle in the design of the pneumatic elevator is that a long transparent tube contains the cylindrical elevator car with a diameter that is slightly smaller than that of the bigger tube. The floor and ceiling of the elevator car are airtight and a vacuum pump is allowed to suck the air out of the top of the long tube. This will cause a vacuum to form at the top of the tube. The air pressure underneath the floor of the car will then slowly push it up as the difference in air pressure between the top and bottom increases. To lower the car, the vacuum pump is turned off. As air returns to the vacuum space, the difference in the air pressure decreases and the elevator gradually goes down. With this system, it can be seen that there is no chance for the car to drop abruptly. The pneumatic elevator lets your home sport that futuristic look of transparent tubes transporting people in science fiction films. With this kind of equipment, you and your family can now enjoy the reality of being transported to the different floors of your residential buildings in these high-tech tubes that do not need cables, pulleys or pistons. There would be no visible material supporting the cab of this vacuum elevator because it is actually air that is performing this function. Plastic and aluminum are used because minimizing the weight is vital in the pneumatic elevator where the difference in air pressure between the top and bottom of the cab is responsible for lifting it or bringing it down.
