Piston ring elasticity refers to the force that the piston ring returns to its original shape after being deformed by an external force. This force keeps the piston ring in close contact with the cylinder wall all the time, and maintains the cylinder pressure under the action of oil sealing and lubrication. When the hardness of the piston ring is high, the elastic force is also large, and vice versa.

After the piston ring is processed and formed, it is larger than the cylinder diameter before it is installed in the cylinder, and it is elliptical. After being installed in the cylinder, it becomes a circle, so the elastic force of the piston ring is produced after the ring diameter is reduced. After the piston ring matched with the cylinder is installed into the cylinder, the gap between the ring openings is suitable, no need to file, the ring fits well with the cylinder wall, and the elasticity is also standard. If the size of the cylinder is inaccurate, that is, it is between two stages, the equipped piston ring must be larger, so you can only file more rings, so that the elasticity will increase, and the outer diameter will also lose round. If the hardness of the piston ring is higher, the lighter one will cause gas blow-by in the cylinder, and the heavier piston ring will roughen the surface of the cylinder wall, and gradually form a scuffed cylinder.
