Abstract

Guarnizione di tenuta per una valvola di un motore a combustione interna, in cui la valvola (1) ha uno stelo (6) scorrevole in una boccola di guida (8) fissata in una sede (10) della testa del motore (12). La guarnizione (24) ha una porzione di tenuta (30) a contatto con lo stelo (6) della valvola (1) ed un'altra porzione di tenuta (34) che stabilisce un contatto di tenuta statica con una superficie della testa (12) circondante lo stelo (6) e la boccola (8).(fig. 1).Seal for a valve of an internal combustion engine, in which the valve (1) has a stem (6) sliding in a guide bushing (8) fixed in a seat (10) of the engine head (12). The gasket (24) has a sealing portion (30) in contact with the stem (6) of the valve (1) and another sealing portion (34) which establishes a static sealing contact with a surface of the head (12 ) surrounding the stem (6) and the bush (8). (fig. 1).
