Valve spring retainer |
摘要 |
A valve spring retainer is fixed at the upper end of a poppet valve via a pair of cotters in a valve-operating mechanism of an internal combustion engine. The valve spring retainer comprises a hollow inverted-frustoconical portion and an outward flange at the end thereof. The lower surface of the outward flange retains the upper end of a valve spring on the lower surface. An annular projection is provided on the outward flange to restrict sideward movement of the valve spring and to increase rigidity of the retainer.
