Note:
1. Sectional view of the elastic mass (The mass itself has good elasticity.)
2. The air pressures inside and outside the elastic mass are equal.
3. The elastic mass is pressed with external pressure, the internal capacity of the elastic mass decreases, and air is discharged from the air vents.
4. Continued pressure on the elastic mass, the elastic mass continues to receive external pressure. When the length decreases by 1/4, the air vents are blocked, and air in the elastic mass cannot be discharged. Under pressure, it functions as a pneumatic spring with increased elasticity.
5. Under more pressure, part of the air inside the elastic mass functions as a pneumatic spring, and another part is discharged out of the elastic mass through air vents.
6. When external pressure disappears, the elastic mass is no longer subject to external pressure, and rebounds quickly. As a result, the capacity inside the elastic mass increases, and air is absorbed into the elastic mass through air vents.
7. With the disappearance of external pressure, the elastic mass elongates the elastic mass continues to take in air through the air vents, and rebounds quickly.
8. Recovery to the original state with its good elasticity, the elastic mass rebounds to its original length.
