Abstract
<B>BOMBA EJETORA A VáCUO<D> Ejetor (1) que compreende dois ou mais bocais (2, 3, 4, 5) montados em série, em que uma corrente de ar alimentada através dos bocais a alta velocidade é usada para criar uma pressão negativa em um espaço externo envolvente (V, V'), o espaço envolvente estando em comunicação de fluxo (10) com pelo menos uma ranhura (7, 8, 9) localizada entre os bocais, em que os bocais estão acoplados em conjunto e montados dentro de um corpo de bocal integrado (1) que tem pelo menos um elemento de válvula flexível (11) montado integralmente com o corpo de bocal para cobrir a comunicação de fluxo (10) com o espaço envolvente após alcançar uma diferença de pressão desejada entre o espaço envolvente e a atmosfera.
