    摘要: A vibration insulator which can compensate for axial eccentricity occurring in a fuel injection valve and suppress vibrations of the valve during operation of a combustion engine and a support structure for the valve. The vibration insulator is interposed between a step height portion of the valve and a shoulder portion. The step height portion is increased in diameter in a tapered fashion and inserted into an insertion hole of a cylinder head. The shoulder portion is annularly extended in an inlet portion of the insertion hole opposed to the step height portion. The vibration insulator includes an annular tolerance ring on an inner circumferential inclined face thereof with recessed tapered faces opposed to the tapered face of the step height portion and which abuts the tapered face. The taper angles of the tolerance ring and of the step height portion are set so as to be different.

    摘要: A fuel injection valve is mounted in a cylinder head by being inserted in an insertion hole provided in the cylinder head. A shoulder section is provided at the inlet portion of the insertion hole to be expanded in an annular shape. The fuel injection valve is provided with a stepped section expanded in diameter in a tapered manner to have a tapered surface facing the shoulder section. A vibration insulator is disposed between the stepped section and the shoulder section. The vibration insulator is provided with a circular annular tolerance ring making contact with the tapered surface of the fuel injection valve. A circular annular sleeve section coaxial with the tolerance ring is integrally formed on the tolerance ring to extend from the surface of a portion of the tolerance ring, the portion not facing the tapered surface of the fuel injection valve.
