Abstract

DISPOSITIVO PARA MEDIR A POSIçãO DE UM PISTãO EM UM CILINDRO, CONJUNTO, MOTOR DE AERONAVE, MACACO, E, DISPOSITIVO DE DOSAGEM. Esta invenção refere-se a um dispositivo para medir a posição de um pistão (2) em um cilindro (1), estendendo-se de acordo com um eixo, o dispositivo compreendendo pelo menos dois sensores de posição (3, 4), respectivamente, compreendendo: -um primeiro membro de sensor (20, 40) integral com um palete de suporte (31) ligado ao pistão (2); um segundo membro de sensor (10, 30) integral como cilindro (1), os primeiro e segundo membros de cada sensor sendo arranjados para serem móveis em translação, um em relação ao outro, ao longo de um eixo paralelo ao eixo do cilindro, onde o dispositivo tem os primeiros membros de sensor (20, 40) integrais com o mesmo palete de suporte (31) sendo conectado ao pistão (2) através de uma ligação de junta de esfera (50). Usando o dispositivo desta invenção, um sensor de posição pode ser arranjado no cilindro, sem ter os esforços transversais sobre o pistão sendo transmitidos ao mesmo, enquanto o pistão permanece livre em rotação ao redor do eixo do barril cilíndrico.
