Abstract
"AMORTECEDOR''. Trata-se de um amortecedor (1) de eixo geométrico longitudinal de revolução (XX'), do tipo constituído por um corpo de amortecedor (2), um pistão principal (4) sustentado por uma haste de pistão (5), uma câmara de compressão principal (3), na qual desliza o pistão principal (4), o pistão dividindo o interior da câmara (3) em uma parte interna posterior, o pistão deslizando de frente para trás quando da compressão do amortecedor (1), um dispositivo de retorno elástico (8), um dispositivo de compensação de volume (9), um fluido hidráulico (7), pelo menos um canal de laminação,caracterizado pelo fato de que o canal de laminação é constituído por pelo menos uma parte da face interna da parede periférica da câmara de compressão principal (3) e pelo menos uma parte da parede periférica externa do pistão principal (4).
