Abstract (en)
The invention relates to a device for guiding and sealing a valve, the stem (10) of which is mounted slidably in a tubular valve guide (14) fitted in the cylinder head (12) of a combustion engine and which projects axially from a bearing surface (20) of the cylinder head, which is perpendicular to the axis (X-X) of the valve and on which bears one end of a return spring (26) for the valve, there being interposed a washer-shaped bearing cup (24), through which passes the projecting part (18) of the valve guide (14). A sealing ring (32) is held axially against this projecting part (18) by means of a bush (30). According to the invention, the bush and the bearing cup are produced in one piece (22), of which the cylindrical part forming a bush (30) extends axially from the cup (24) beyond the free end (50) of the projecting part (18) of the valve guide (14) by means of an end portion (40), the inner surface of which completely envelops the sealing ring (32). <IMAGE>
