  • Patent number: 10950874
    Abstract: A gasket manufacturing method is provided. The gasket has a base material with a bead and an elastomeric gasket body disposed in a top portion of the bead. The method includes sequentially forming the bead on one part of a plane of the base material and applying a molding material of the gasket body to the top of the bead. When forming the bead on the one part of the plane, a protrusion is formed in each end in the width direction in the top of the bead. The protrusions are utilized as a coating width defining means of the molding material when applying the molding material to the top of the bead.

  • Patent number: 8763588
    Abstract: 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.
