Abstract
A locator for use in a valvetrain of a cylinder head of an internal combustion engine having a valve substantially concentrically aligned with both a valve spring and a support, the support at least partially extending into the valve spring. The locator includes an annulus seat that supports the valve spring. The locator further includes a tapered ring operatively attached to the seat that has a tapered inner surface, for at least partially accommodating the support of the valvetrain therein, and a tapered outer surface, for at least partially engaging and concentrically aligning with the valve spring. The locator also includes a plurality of radially-spaced lobes. The lobes are disposed on the inner surface of the ring and at least partially engage the support such that the locator substantially concentrically aligns the valve spring with the valve and the support.
