摘要

The valve spring disk (11) can be directly engaged in an annular groove in the valve stem. The valve spring rests on an annular disk (12) and two support tongues (13) extending radially inward from it. The radially inner edges of the tongues have recesses for fitting in the annular groove, reducing the tongue end spacing for axial support from the spring side.
