Abstract

DETECTOR DE SOBREPRESSÃO E DE TALONAGEM PARA AMORTECEDOR OU SIMILAR. A invenção refere-se a um detector de sobrepressão e de talonagem, o detector comportando um corpo oco (11) no qual desliza com estanqueidade um pistão (14) destinado a ser submetido a uma pressão por intermédio de uma entrada (12) do corpo em comunicação com um alojamento no qual reina a referida pressão, o pistão sendo retido em posição ao encontro da pressão por um meio de retenção com limiar (21) adaptado para liberar o pistão quando a pressão atinge ou ultrapassa o referido limiar de modo que o pistão seja impulsionado sob o efeito da pressão em direção a uma posição de indicação, e em que o pistão é solidário de um dedo (27) em saliência da entrada do corpo para poder ser impulsionado ao encontro do meio de retenção com limiar.
