Abstract

"AERADOR E MISTURADOR APRIMORADOS". Um difusor que inclui um cilindro aberto em uma extremidade e fechado na extremidade oposta, sendo a extremidade aberta do cilindro protegida para fornecimento de ar: a parede do difusor é formada por uma pluralidade de orifícios em toda sua extensão, cada orifício apresentando um diâmetro maior na parte externa da parede do difusor do que na parte interna da parede do difusor; o eixo longitudinal de cada orifício é inclinado em um ângulo agudo com relação ao raio e ao eixo longitudinal do difusor, e a orientação de cada orifício com relação ao eixo longitudinal do difusor apresenta-se de tal forma que, quando o difusor é rotacionado sobre seu eixo longitudinal em uso, a extremidade frontal de cada orifício encontra-se em uma elevação mais alta do que a extremidade posterior de cada orifício.
