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).
