ABSTRACT:
The upper retainer for retaining an upper portion of a valve spring is shaped like a perforated spinning top and is axially dividable into two identical elements which are coaxially disposed about the upper portion of the valve stem when assuming its operative condition. The retainer has, when assuming the operative position, a configuration which comprises a collar portion which is sized to be coaxially disposed within an upper portion of the valve spring, an annular flange portion extending radially outward from the upper end of the collar portion and engaging with the upper end of the valve spring, and means for achieving a spline connection between the central portion of the retainer and the upper portion of the valve stem.
