Abstract

a presente invenção refere-se a um conjunto de braço osci-lante (54) para uma válvula (36) tendo uma válvula (38), um ajustador (52) e um lóbulo (50) do eixo de comando (28). um eixo (56) giratori-amente que suporta um mancal (58) é fornecido para encaixar o lóbulo (50). um braço (60) é fornecido com uma almofada (62) para encaixar a válvula (38) e um soquete (64) para encaixar o ajustador (52). paredes (70) dispostas entre a almofada (62) e o soquete (64) definem um vale (72) para o eixo (56). as superfícies do mancal com abertura para cima (74) dispostas entre a almofada (62) e o soquete (64) giratoriamente suportam o eixo (56) quando o mancal (58) encaixar o lóbulo (50). um par de elementos de retenção (76) se estende das paredes (70) ao vale (72) acima das superfícies do mancal (74) de modo que o eixo (56) seja impedido de mover para fora do vale (72) na ausência do encaixe entre o mancal (58) e o lóbulo (50).
