Beschreibung
Zusammenfassung:	A variable damping valve of an oil damper comprises a valve body and a fixed valve sleeve, the valve body is provided with an upward opening, oil passing through holes are formed in the bottom and the side face of the valve body, and the fixed valve sleeve is pressed in the oil passing through hole in the bottom of the valve body in an interference mode. The variable damping valve is characterized in that a small elastic damping valve with damping rigidity and a large elastic damping valve with the damping rigidity larger than that of the small elastic damping valve are installed in the valve body; the large elastic damping valve is coaxially pressed on the fixed valve sleeve, the small elastic damping valve is coaxially installed in the large elastic damping valve, the small elastic damping valve and the large elastic damping valve are each provided with an oil passing hole communicated with the oil passing through hole, and the small elastic damping valve and the large elastic damping valve sequentially mov
