Abstract

ABSORVEDOR DE CHOQUE PARA UM TREM DE ATERRISSAGEM DE AERONAVE, E, TREM DE ATERRISSAGEM. A invenção relaciona-se a um absorvedor de choque para um trem de aterrissagem de aeronave, o absorvedor de choque incluindo um cilindro principal (1) no qual uma haste (2) está montada para deslizar telescopicamente, o absorvedor de choque tendo uma ou mais câmaras pneumáticas (12, 22) cheias com gás, uma provisão de fluido hidráulico (5), e meio de estrangulamento (14, 24) para estrangular o fluido hidráulico tal que quando o absorvedor de choque é encurtado, o gás nas câmaras pneumáticas seja comprimido e o fluido hidráulico seja estrangulado, em que as câmaras pneumáticas são contidas completamente em um ou mais cilindros auxiliares (10, 20) externos ao cilindro principal, e em cada um de qual um pistão vedado (11, 12) é montado de modo deslizante para separar uma câmara pneumática (12, 22) contida em dito cilindro auxiliar externo de uma câmara de fluido (13, 23) em comunicação de fluxo de fluido com o cilindro principal. De acordo com a invenção, meio de estrangulamento (14, 24) está disposto na entrada de uma conexão de fluxo de fluido entre o cilindro principal (1) e os cilindros auxiliares (10, 20).
