Valve spring retainer and a valve operating mechanism

Image Number 7 for United States Patent #6293240.

The valve spring retainer has an intermediate portion and an outer flange which is engaged with the upper end of a valve spring. The lower surface of the outer flange is radially and inclined towards the valve spring to decrease wear which is caused by engagement with the valve spring. There is also provided a valve operating mechanism which has a valve spring retainer which has a projection on the lower surface so as to prevent wear.
