Abstract
ÊMBOLO PARA COMANDO DE ORIENTAÇÃO COM CREMALHEIRA. A invenção é relativa a um êmbolo de acionador de orientação com cremalheira (6) para trem de aterrissagem de aeronave (1). O êmbolo compreende um corpo (10) feito de liga leve que tem uma parte corrente (11) exteriormente rosqueada terminada de um lado por um ressalto (12) e prolongada do outro lado por uma saia (13), o corpo (10) recebendo com atarraxamento uma bucha (14) feita de bronze rosqueada que apresenta em sua parede externa pelo menos uma canelura (16) de recepção de uma junta de estanqueidade (22), a saia apresentando uma perfuração para receber um pino (15) de solidarização do êmbolo à cremalheira, a bucha (14) se estendendo em serviço entre o ressalto e o pino (15) para ser bloqueada axialmente entre o ressalto (12) e o pino (15).
