摘要:
A valve stem seal (1) seals a valve stem (4) that is reciprocally movable in an axial direction. The valve stem seal includes a base body (8) that is connectable with a valve stem guide (6). A first seal lip (10) is resiliently positioned relative to the base body via an elastic connection (16) and seals the valve stem relative to an oil chamber (24). A second seal lip (12) is spaced in the axial direction (2) from the first seal lip and seals the valve stem relative to a gas chamber. The second seal lip is also resiliently positioned relative to the base body via the elastic connection.
