Abstract

"UNIDADE DE VáLVULA PARA CONTROLAR A DISTRIBUIçãO DE UM GáS COMBUSTìVEL". A invenção refere-se a uma unidade de válvula para controlar a distribuição de um gás combustível através de um duto de distribuição (3) compreende um assento de válvula (6) no duto, um elemento de fechamento (5) associado ao assento, um acionador acionado a motor (7) que atua no elemento de fechamento para controlá-lo de modo a abrir/fechar o assento de válvula, bem como uma unidade eletromagnética (22) com uma primeira porção (23) que carrega um enrolamento de magnetização (24) e uma segunda porção (25) que pode ser fixada firmemente a primeira porção por meio de magnetização. A unidade eletromagnética (22) é associada com ao acionador para atuar sobre o elemento de fechamento (5) de modo a fechar o assento de válvula (6), independentemente da posição operativa do acionador (7), quando da ocorrência de uma condição predeterminada que requeira que o assento de válvula seja fechado e o dispositivo acionador (7) é móvel juntamente com a segunda porção (25) da unidade eletromagnética durante o movimento para controlar o elemento de fechamento (5) de modo a abrir/fechar o assento de válvula, a primeira porção (23) da unidade eletromagnética sendo conectada a uma estrutura estacionária da unidade de válvula.
