Abstract

MóDULO DE AMORTECEDOR DE MOLA PNEUMáTICA. A presente invenção refere-se a um módulo de amortecedor de mola pneumática com um amortecedor (1) e um êmbolo roll-off (5) que com uma abertura no fundo do êmbolo está disposto sobre a extremidade superior do amortecedor, sendo que o fundo do êmbolo se apóia no tubo externo (16) do amortecedor através de um flange anelar (2). Na superfície interna da cabeça do êmbolo (6) está fixado centralmente um tubo (15) que em estado montado abraça o amortecedor (1) e também se apóia sobre o flange anelar (2) do amortecedor (1), sendo que a superfície interna da cabeça do êmbolo e o fecho superior do amortecedor estão distanciados um do outro através de uma fenda.
