Abstract

Viene descritta una guarnizione di tenuta (1) per uno stelo (2) scorrevole contro l'azione di mezzi elastici (22), in particolare per uno stelo (2) valvola (3) di un motore a combustione interna, avente un elemento elastomerico (5), conformato a manicotto, costituito da una porzione di tenuta (6) atta a cooperare con lo stelo (2) e da una porzione di montaggio (7) ed una armatura di irrigidimento (12) ricavata solidale con la porzione di montaggio (7); l'armatura (12) è provvista di una porzione di appoggio e centraggio (21) per i mezzi elastici (22), si estende radialmente ed assialmente verso l'esterno dall'elemento elastomerico (5), da banda opposta rispetto alla porzione di tenuta (6). (Figure 1 e 2)A seal (1) is described for a stem (2) sliding against the action of elastic means (22), in particular for a valve stem (2) (3) of an internal combustion engine, having an elastomeric element (5), shaped like a sleeve, consisting of a sealing portion (6) adapted to cooperate with the stem (2) and a mounting portion (7) and a stiffening armature (12) obtained integrally with the mounting portion (7); the armature (12) is provided with a support and centering portion (21) for the elastic means (22), extends radially and axially outwards from the elastomeric element (5), from the opposite band with respect to the portion of seal (6). (Figures 1 and 2)
