Abstract

Patente de Invenção: <B>"VáLVULA DE CONTROLE PARA COMPRESSOR DE CAPACIDADE VARIáVEL"<D>. Uma válvula de controle, para um compressor de capacidade variável, é provida com um elemento de válvula de esfera (37), para abrir ou fechar passagens de comunicação (32, 34, 33), para comunicação de uma porta de sucção de um compressor com um cárter. O elemento de válvula de esfera (37) é energizado para se mover em uma direção de fechamento de válvula, por meio de uma força de mola de uma mola em espiral de compressão (44). A válvula de controle para um compressor de capacidade variável é provida com um dispositivo de fole (40), o qual direciona o elemento de válvula de esfera (37) para se mover em uma direção de abertura de válvula, que é afetada por uma pressão de sucção do compressor. O elemento de válvula de esfera (37) é diretamente conectado ao dispositivo de fole (40), com a utilização do elemento de válvula de esfera (37) como uma esfera centrípeta automática. Um alojamento de válvula (31) é provido com um tubo oco (49), para a introdução de uma pressão de envio, o qual é unido ao elemento de válvula de esfera (37) em uma extremidade do mesmo, e exerce diretamente a pressão de envio do compressor sobre o elemento de válvula de esfera (37), para movimento em uma direção de abertura de válvula. Uma mola em espiral de compressão (50) energiza o elemento de válvula de esfera (37), para se mover em uma direção de abertura de válvula, através do tubo oco (49), para a introdução da pressão de envio.
