摘要：
A valve stem oil shield comprises a cup-shaped deflector having a radial flange with an aperture therein for the acceptance of the valve stem. An annular grommet of U-shaped cross-section is disposed between the deflector and the valve stem to mechanically secure the oil shield to the valve stem. Leg portions of the grommet slidably engage the deflector thereby to effect a seal between the deflector and valve stem.
