Abstract

"VEDAçãO DE HASTE DE VáLVULA DE DUAS PEçAS". A presente invenção refere-se a um conjunto de vedação de haste de válvula de duas peças incluindo primeiro e segundo envoltórios geralmente cilíndricos, um dos quais é parcialmente e axialmente embutido ou inserido dentro do outro. O conjunto de vedação de haste de válvula também inclui uma parte de engate em um dos envoltórios para engatar de forma justa o outro envoltório a fim de impedir substancialmente ou pelo menos minimizar a possibilidade de separação axial dos envoltórios durante a montagem subseq³ente dentro de um motor ou outro dispositivo contendo válvula. O conjunto também pode opcionalmente incluir uma descontinuidade em um dos envoltórios para reter axialmente ou intertravar axialmente os envoltórios a fim de impedir substancialmente ou pelo menos minimizar tal possibilidade de separação axial.
