Abstract

UMA VáLVULA DE RETENçãO COM UMA VEDAçãO DE BOBINA ESPIRAL E UNIDADE DE INJEçãO Uma vedação para uma válvula de retenção para uma máquina de moldagem de metal. A vedação é fornecida pela combinação de uma ranhura periférica em uma superfície externa da válvula de retenção e um núcleo enrolado de modo helicoidal na ranhura. A bobina enrolada de modo helicoidal é expansível em engate de vedação com uma parede cilíndrica da máquina de moldagem. A bobina enrolada de modo helicoidal pode ser móvel lateralmente em uma ranhura entre uma posição aberta do canal de material fundido e uma posição fechada do canal de material fundido para abrir ou vedar o canal de material fundido.
