Abstract

Patente de Invenção:<B>"MéTODO, MEMBRO DE FORNECIMENTO DE PRESSãO E SISTEMA DE FORNECIMENTO DE PRESSãO PARA PóS-ALIMENTAçãO DE FUNDIDOS"<D>. Quando vazando em cavidades de fundição (não-mostradas) em moldes de fundição (6) possuindo reservatórios de alimentação posterior (8), lanças tubulares (1) são introduzidas, primeiramente com sua ponta a uma curta distância do reservatório de alimentação posterior (8), depois do que as lanças (1) são pressurizadas a partir de uma câmara de pressão (3) e por meio de um membro (5) com uma superfície inclinada apertando para baixo pela última e curta distância até o reservatório de alimentação posterior (8) de forma a pressurizar este último. Com este arranjo é possível pressurizar os reservatórios de alimentação posterior (8) sem a necessidade de equipar os moldes de fundição (6) com equipamento complicado e suplementar e sem o risco do metal derretido ser desnecessariamente pressurizado.
