Abstract

AMORTECEDOR PARA TREM DE POUSO DE AERONAVE. A invenção se refere a um amortecedor para trem de pouso de aeronave que tem dois elementos (1, 2) montados para deslizar telescopicamente um no outro e que definem um volume interno cheio com fluido hidráulico e com gás e separado em pelo menos duas câmaras (7, 8) por uma separação (5) que compreende pelo menos um orifício de laminação (10) pelo qual o fluido hidráulico transita de uma câmara para a outra notadamente por ocasião de uma compressão do amortecedor. De acordo com a invenção, a separação compreende pelo menos um orifício de desgaseificação para permitir a transferência de gás de uma câmara para a outra quando o trem de pouso está na posição estendida, o orifício de desgaseificação era deslocado em altura em relação ao orifício de laminação para se encontrar acima desse último quando o trem de pouso está na posição estendida.
