Abstract
a presente invenção refere-se a um absorvedor de choque dotado de: uma primeira passagem (101) através da qual um fluido de trabalho, acionado por um pistão (18), escoa para fora de uma câmara (19); uma segunda passagem (181) que é fornecida em paralelo com a primeira passagem (101); um mecanismo de geração de força de amortecimento (41) que é fornecido na primeira passagem (101) e que gera uma força de amortecimento; um membro de invólucro cilíndrico (140) dentro do qual pelo menos uma parte da segunda passagem (181) é formada; um disco anular (134) que, dentro do membro de invólucro (140), é sustentado no lado periférico externo ou no lado periférico interno e em que um membro de vedação anular (156) é fornecido no lado não sustentado para formar uma vedação com o membro de invólucro (140); e duas câmaras (171, 172) dentro do membro de invólucro (140) fornecidas separadas pelo disco (134), em que o disco (134) bloqueia o fluxo na segunda passagem (181).
