The inlet of the high-pressure tank is a one-way intake piston. When the cylinder is inflated, the piston opens and the gas in the cylinder enters the high-pressure tank. When the cylinder lifts the suction, the piston closes. A high air pressure is formed in the high pressure tank to inflate the tire.
The high pressure gas cylinder is thinner than the ordinary gas cylinder. According to the relationship between pressure, pressure and area, the pressure to be applied is small, but the number of times to inhale is increased. The pressure of the person using the ordinary air pump is greater than the pressure of the tire to get in and out.
Since the diameter of the tire valve core is small, even if a certain pressure difference is generated, according to the fluid mechanics, the pressure balance between the tire and the gas cylinder takes a long time, so that it is not cost-effective to pump, because every time you hit the end, you have to wait for a long time. The compressed air at the bottom of the time can enter the tire.
If the high pressure cylinder is added, the check valve between the pump and the high pressure tank can be made relatively large, so that the air compressed by the pump can quickly enter the high pressure tank, and the air can be quickly and efficiently ventilated while the high pressure tank maintains high pressure and gas. Sources are constantly being imported into the tires.
