Pneumatic Tyre Pump - Principle of Pneumatic Tyre Pump
When using a bicycle pump, you need to connect its outlet tube to the tire's air valve. The air valve's role is to allow air to enter the tire from the pump but prevent air from flowing back into the pump. There is a gap between the piston and the wall of the pump, and there is a concave rubber bowl on the piston. When you pull the piston up, the volume of air below the piston increases, causing the pressure to decrease. The air above the piston then squeezes into the space below the bowl. When you press the piston down, the volume of air below the piston decreases, causing the pressure to increase. This makes the rubber bowl tightly against the wall of the pump to prevent air from leaking above the piston. Continue to press the piston down, and when the air pressure is strong enough to open the valve core of the tire, "
Compressed airEnter the tire. At the same time, the air outside the cylinder enters the upper part of the piston through the gaps in the cylinder.
