Abstract

cilindro hidropneumático com posição de parada controlada cilindro à gás com parada controlada para uma matriz de amortecedor, que compreende um chassi cilíndrico oco (1) , uma base de chassi (4) fixada a uma primeira extremidade (la) do chassi de cilindro (1) e uma barra no interior do chassi de cilindro (1), em que a mencionada barra (2) é axialmente móvel de uma posição de repouso (pr) para uma posição de parada. o cilindro também compreende uma câmara principal (5), uma câmara auxiliar independente da câmara principal (5) e um duto de fluxo (20) para comunicar a câmara principal (5) com a câmara auxiliar. o duto de fluxo (20) fica disposto na barra (2) e a câmara principal (5) compreende um fluido gasoso e um fluido oleoso no seu interior quando a barra (2) estiver na posição de repouso (pr) e compreende apenas fluido oleoso quando a mencionada barra (2) estiver na posição de parada.
