Abstract

"CONJUNTO DE APERTO DE MOLA PNEUMáTICA". A presente invenção refere-se a uma mola pneumática tendo um par de elementos de extremidade axialmente espaçados (4, 5) e uma luva flexível elastomérica intermédias (7) se estendendo entre eles e formando uma câmara de pressão de fluido (16). Um anel de aperto anular (15) tem pelo menos uma nervura que se estende radialmente (25) formada em uma superfície interna com vedação (22) que se alinha radialmente com pelo menos um recesso cóncavo (38, 39) formado em uma superfície de vedação (37) de um dos elementos de extremidade. O elemento de extremidade também tem pelo menos uma nervura que se estende radialmente (43, 44) que se alinha com pelo menos um recesso formado (26, 27) na superfície de vedação do anel de aperto. A nervura e recesso formados no anel de aperto são mais longos e mais profundos do que as nervuras e recessos na superfície de vedação do elemento de extremidade para proporcionar uma ação de aperto mais agressiva na superfície externa da luva flexível do que a ação de aperto na superfície interna ou forro interno da luva.
