Abstract

Patente de Invenção: <B>"CORPO DE VáLVULA EM FORMA DE BORBOLETA COM BORBOLETA AUTOCENTRADA"<D>. Trata-se de um corpo de válvula em forma de borboleta para dispositivo de injeção de combustível para motor à combustão interna, comportando uma caixa (2), na qual é disposto um conduto de admissão de ar (3) que compreende uma parede interna (4), uma válvula em forma de borboleta (6) em forma de disco que divide esse conduto em uma parte a montante (8) e uma parte a jusante (9) e deslocável entre uma posição de abertura mínima e uma posição de abertura máxima, a parte da borboleta que gira em direção à parte a montante do conduto, respectivamente em direção à parte a jusante, a partir da posição de abertura máxima, tendo uma forma de semidisco plano (12, 13) possuindo uma bordaInvention Patent: <B> "BUTTERFLY VALVE BODY WITH AUTOCENTRATED BUTTERFLY" <D>. It is a butterfly-shaped valve body for a fuel injection device for an internal combustion engine, comprising a box (2), in which an air intake duct (3) is provided, comprising an internal wall ( 4), a butterfly-shaped valve (6) in the shape of a disk that divides this duct into an upstream part (8) and a downstream part (9) and displaceable between a minimum opening position and a maximum opening position , the part of the butterfly that rotates towards the upstream part of the duct, respectively towards the downstream part, from the maximum opening position, having a flat semidisk shape (12, 13) having an edge
