Abstract

"AMORTECEDOR DE CHOQUE PARA AVIãO". A presente invenção refere-se a um amortecedor de choque para avião com uma região cheia com líquido, que abrange uma primeira câmara, que serve como elemento de amortecimento e na qual está alojado deslocável um elemento de estrangulamento, que é movimentado quando do movimento do amortecedor de choque na primeira câmara, bem como uma segunda câmara cheia com gás, que serve como mola de gás e cujo volume depende da posição de inserção do amortecedor de choque e é independente do volume do líquido na região cheia com líquido."AIR SHOCK SHOCK". The present invention relates to a liquid-filled region airplane shock absorber comprising a first chamber which serves as a damping element and in which a throttling element is movably housed which is moved upon movement of the shock absorber in the first chamber, as well as a second gas-filled chamber, which serves as a gas spring and whose volume depends on the insertion position of the shock absorber and is independent of the volume of the liquid in the liquid-filled region.
