Abstract

resumo "sistema de suspensão pneumática de um veículo a motor" a presente invenção se refere a um sistema de suspensão pneumática de um veículo automóvel, com pelo menos dois foles (3, 4), os quais estão associados a molas pneumáticas dispostas em lados opostos do veículo de um eixo do veículo, e que podem ser ligados a, ou desligados de, uma linha de pressão principal (9), através de linhas de ligação (7, 8) providas respectivamente de uma válvula de regulação de nível (5, 6), em que a linha de pressão principal (9), através de uma válvula de pressão principal (10), pode ser alternadamente ligada a uma fonte de ar comprimido (12) e a um dissipador de ar comprimido (11), e em que as linhas de ligação (7, 8) dos pelo menos dois foles (3, 4) estão em ligação entre si através de uma linha de ligação (13) dotada de um estrangulamento (14) e que pode ser fe-chada por uma válvula de fecho (15, 21). para simplificar e aumentar a fiabilidade funcional do sistema de válvulas em questão, se prevê que a válvula de fecho (21) seja concebida para ser acionada mecanicamente, e esteja de tal modo acoplada à válvula de regulação de nível (6) do fole (4) disposto no lado do veículo externo à banda de rodagem, que a válvula de fecho (21) é aberta quando a válvula de regulação de nível (6) é fechada e é fechada quando a válvula de regulação de nível (6) é aberta.
