Abstract

"EJETOR PARA UM SISTEMA DE CICLO DE EJETOR". Em um ejetor (400) usado para um sistema de ciclo de ejetor, um bico (410) tem uma primeira passagem de refrigerante (411), uma segunda passagem de refrigerante (412) e uma terceira passagem de refrigerante (413), nesta ordem, em uma direção de fluxo de refrigerante, de uma entrada de refrigerante em direção a uma saída de refrigerante do bico. A primeira passagem de refrigerante, a segunda passagem de refrigerante e a terceira passagem de refrigerante são feitas com formas cilíndricas, respectivamente, cada uma com um diâmetro de passagem constante. Além disso, uma região de aumento de pressão (420) do ejetor é também feita numa forma cilíndrica com um diâmetro de passagem constante. Dessa maneira, o ejetor pode ser fabricado facilmente com baixo custo.
