<p>Valve stem seal intended to be pushed onto a valve stem guide (8) held in the cylinder head (12) of an internal combustion engine, comprising a reinforcing tube (26) which is connected at one end to a first sealing lip (30) of annular design made of flexible material and, at the other end, ends in a radially outward-projecting first flange (18) which can be supported on the cylinder head (12). The reinforcing tube (26) is connected to a second sealing lip (34) made of flexible material which projects beyond the first flange in the axial direction and the second sealing lip (34) is at a radial distance from the valve stem guide (8) and can be brought into engagement with the annular surface of the cylinder head which surrounds the valve stem guide. <IMAGE></p> |
