Abstract

são descritos dispositivos para produção de vácuo usando o efeito venturi, tendo uma passagem motriz convergente em direção a uma câmara de aspiração, uma passagem de descarga divergente que se afasta da câmara de aspiração, e uma passagem de aspiração, todas em comunicação com a câmara de aspiração. a passagem motriz apresenta uma única entrada e subdivide-se a jusante da mesma em uma pluralidade de subpassagens, cada uma delas conduzindo a uma saída da pluralidade de saídas motrizes, que estão espaçadas de uma entrada de descarga da passagem de descarga para definirem uma abertura de venturi. um inserto do tipo flecha, tendo uma pluralidade de nervuras que se estendem entre uma superfície externa do corpo principal de formato geralmente cônico do inserto e uma superfície interna da passagem motriz, está disposto na passagem motriz. as nervuras dividem a passagem motriz na pluralidade de subpassagens, cada uma convergindo o fluxo de fluido sobre a sua superfície externa em direção a uma saída da pluralidade de saídas motrizes.
