Abstract

"VáLVULA DE CONTROLE PARA COMPRESSOR DE DESLOCAMENTO VARIáVEL". Que inclui um cilindro de acomodação (52), uma bobina (61), um estator (53), um êmbolo (56) e um corpo de válvula (45). A força eletromagnética é gerada entre o estator (53) e o êmbolo (56), e o êmbolo (56) movimenta-se relativamente ao estator (53). O corpo de válvula (45) ajusta o grau de abertura de um orifício de válvula (43). Uma superfície plana (81) e uma parede periférica (82) são formadas em uma extremidade do estator (53). A parede periférica (82) possui uma seção transversal cónica com uma superfície interna inclinada (82a). A superfície interna inclinada (82a) e a superfície plana (81) definem um rebaixo (83). O êmbolo (56) tem uma parte de tronco de cone (86). A parte de tronco de cone (86) inclui uma superfície distal plana (84) e uma superfície inclinada anular (85). O ângulo de cone (0) da parede periférica (82) é igual ou menor que vinte graus. O diâmetro da superfície distal plana (84) da parte de tronco de cone (86) é igual ou maior que 80% do maior diâmetro da superfície inclinada anular (85).
