Patent ID: 7032553

Claim:
An assembly, comprising: a) an adjusting body that includes an axis and that has, at least in part, been cold formed to provide a cavity; b) the cavity of the adjusting body has, at least in part, been machined to provide an inner surface that includes an annular surface that is located between a first cylindrical surface and a second cylindrical surface; c) the annular surface has been machined so that the annular surface is oriented to be generally orthogonal to the axis of the adjusting body; d) a valve lifter body that has been cold formed to provide a first lifter cavity that includes a first inner lifter surface and a second lifter cavity; e) the valve lifter body is provided with an axis, a first end that includes a first opening, a second end that includes a second opening, and an outer lifter surface that encloses the first lifter cavity and the second lifter cavity; f) the first inner lifter surface of the first lifter cavity has, at least in part, been cold formed into the first end of the valve lifter body to provide a first wall, a second wall, a third wall, a fourth wall, a first angled wall, a second angled wall, a third angled wall, and a fourth angled wall that extend axially into the valve lifter body from the first end and a first angled lifter surface, a second angled lifter surface, a third angled lifter surface, and a fourth angled lifter surface that are generally oriented to be at angle relative to the plane of the annular surface of the adjusting body; g) the first angled lifter surface has been cold formed to extend from the first angled wall and is located adjacent to the first wall and a first curved surface; h) the second angled lifter surface has been cold formed to extend from the fourth angled wall and is located adjacent to the first wall and a second curved surface; i) the third angled lifter surface has been cold formed to extend from the second angled wall and is located adjacent to the second wall; and j) the fourth angled lifter surface has been cold formed to extend from the third angled wall and is located adjacent to the second wall.
