Abstract

Patente de Invenção: <B>"AMORTECEDOR PNEUMáTICO COM SANFONA ROLIçA"<D>. Em um amortecedor pneumático com sanfona roliça (2), no qual um pistão de deslizamento (8) está fixamente atarraxado em uma sanfona roliça (6) do amortecedor pneumático (2), o volume do pistão (8a) deverá ser aproveitado para uma característica molar macia, sendo que este volume do pistão (8a) e o volume (6a) da sanfona roliça (6) devem ser interligados. Com o auxílio de uma barra rosqueada (10) suficientemente extensa, o anel vedante configurado na borda inferior (6c) da sanfona roliça (6), está fixamente protendido entre um disco tensor (12), provido de orifícios (14) e a face vedante (8c) do pistão. O disco tensor (12) pode ser uma gamela de embutição profunda/perfilada, com várias perfurações (14).
