Patent ID: 8800534

Claim:
A vibration isolation fuel rail mounting arrangement comprising: a fuel rail having a mounting portion; an aperture in the mounting portion of the fuel rail; a support member; a fastener extending through the aperture along a central axis, the fastener having a first end and, an opposed second end, and a diameter d, the fastener configured to secure the fuel rail with respect to the support member; a first stacked-layer isolator positioned on a first side of the mounting portion, compressed between the first end of the fastener and the mounting portion of the fuel rail by tightening of the fastener, the first stacked-layer isolator including an elastomer layer having a compression area spaced from the fastener and extending across a width measured in a radial direction, a mid-width point being defined halfway along the width of the compression area; and a second stacked-layer isolator positioned on a second side of the mounting portion, compressed between the mounting portion and the support member by tightening of the fastener, the second stacked-layer isolator including an elastomer layer having a compression area spaced away from the fastener and extending across a width measured in a radial direction, a mid-width point being defined halfway along the width of the compression area, wherein the mid-width point of each elastomer layer compression area is spaced away from the central axis by a distance between about 1.5d and about 3.0d; and wherein each of the first and second stacked-layer isolators includes a plurality of discrete rigid members and a plurality of discrete elastomer members arranged such that a discrete elastomer member defines an elastomer layer interposed between any two adjacent rigid members.
