Abstract

são descritos dispositivos venturi que possuem um corpo que define um conduto possuindo um orifício venturi. a jusante e contornando o orifício venturi há uma válvula de retenção de desvio que define uma cavidade interna possuindo um primeiro assento, um segundo assento, uma porta de entrada, pelo menos duas portas de saída e um membro de vedação encaixado nela que pode ser transladável entre uma posição fechada contra o primeiro assento e uma posição aberta contra o segundo assento. as duas portas de saída da válvula de retenção de desvio entram no conduto em posições opostas dispostas a uma distância a partir de uma parte superior do conduto, que está localizada no plano sagital mediano do corpo. adicionalmente, uma transição de uma seção afunilada a jusante do orifício venturi e a montante de cada uma das duas portas de saída para uma seção de descarga a jusante das duas portas de saída forma uma superfície interior continuamente afunilada (cônica) do conduto.
