Abstract

Patente de Invenção: "CORPO BORBOLETA QUE POSSUI UMA BORBOLETA MUNIDA DE UM RECORTE". Trata-se de um corpo borboleta (1) para dispositivo de injeção de combustível para motor de combustão interna, que possui uma caixa (2) na qual é disposto um conduto (3). Uma borboleta (6) em forma de disco pivota nesse conduto que ela divide em uma parte a montante (8) e uma parte a jusante (9). A borboleta possui uma aba alta (12) voltada para a montante e uma aba baixa (13) voltada para a jusante. Um relevo vazado (2 1) é disposto na face a jusante (16) de uma porção (20) da aba alta (12) da borboleta que sofre o máximo de velocidade do gás, e o relevo vazado (21) desemboca radialmente na face lateral periférica da borboleta (6) sendo delimitado por superfícies (25, 26, 27) cujas interseções com a face a jusante (16) são arestas vivas (25a, 26a, 27a).
