Claim Text:
1. A damping element configured to damp a vibration transmitted between an injection valve body with a central longitudinal axis and a cylinder head of an internal combustion engine, the damping element comprising: a ring-washer-shaped base body having an upper surface, a lower surface and an inner circumference, the base body adapted to encircle an injection valve body and upon assembly lie between the injection valve body and a step formed in a cylinder head recess receiving an injection valve body such that the base body lower surface is located a distance above not in contact with the cylinder head recess step; first and second contact sections fixedly coupled to the upper surface of the base body and protruding beyond the base body in a first axial direction; and a third shaped contact section fixedly coupled to the lower surface of the base body and protruding beyond the base body in a second axial direction opposed to the first axial direction for minimally contacting a cylinder head recess step upon assembly and during engine operation, wherein the first contact section has a radial distance from the inner circumference of the ring-washer-shaped base body which is different than a radial distance of the second contact section from the inner circumference of the ring-washer-shaped base body, and the radial distance of the third contact section from the inner circumference having a value between the values of the radial distances of the first and second contact sections from the inner circumference.
