Abstract

"MEDIDOR VOLUMéTRICO DE FLUIDOS". A invenção refere-se ao campo técnico dos medidores volumétricos de fluidos de pistão oscilante. O medidor compreende uma câmara de medição cilíndrica que inclui uma parede lateral (2), um fundo (1) e uma tampa (3), um cilindro inferior (4) e um cilindro superior (5) que tem o mesmo diâmetro, o qual é menor do que o diâmetro da dita câmara, um orifício de entrada e um orifício de saída (8) para respectivamente admitir um fluido e evacuar um fluido da dita câmara, um pistão cilíndrico (11) disposto excentricamente e guiado cinematicamente dentro da dita câmara e efetuando um movimento oscilatório dentro da dita câmara (30) como um resultado do deslocamento de um volume de fluido, e uma divisória fixa (9) entre o dito orifício de entrada e o dito orifício de saída (8), que fica radialmente entre a dita parede lateral (2) e os ditos cilindros inferior e superior (4, 5), e que fica axialmente entre o dito fundo (1) e a dita tampa (3), a dita parede lateral (2) incluindo uma cavidade vertical (16) na vizinhança da dita divisória fixa (9). A dita cavidade (16) está separada dos ditos orifícios de entrada e de saída e passa através da dita parede lateral (2) pelo menos parcialmente por dentro da altura da dita parede.
