Abstract

VáLVULA ELETROMAGNéTICA DE CONTROLE DO DESLOCAMENTO VOLUMéTRICO EM UM COMPRESSOR COM DESLOCAMENTO VOLUMéTRICO VARIáVEL DO TIPO SEM EMBREAGEM. Uma válvula eletromagnética de controle do deslocamento volumétrico em um compressor com deslocamento volumétrico variável do tipo sem embreagem é descrita. A válvula de controle inclui um corpo da válvula, um dispositivo eletromagnético de acionamento, uma mola amortecedora e uma mola de impulsão. O dispositivo eletromagnético de acionamento aciona o corpo da válvula em direção a uma posição na qual se fecha o orifício da válvula. A mola de amortecimento impulsiona o corpo da válvula em direção a uma posição na qual se fecha o orifício da válvula. A mola de impulsão impulsiona o corpo da válvula em direção contrária à posição na qual se fecha o orifício da válvula e contra a força elástica de impulsão do membro elástico de impulsão. Para uma condição onde nenhuma corrente seja fornecida ao dispositivo eletromagnético de acionamento, o corpo da válvula pode se mover na direção contrária à posição na qual se fecha o orifício da válvula e contra a força elástica de impulsão do membro elástico de impulsão.
