Abstract

ESTRUTURA DE SUCÇçO DE FLUIDO REFRIGERANTE EM COMPRESSOR COM PISTçO DE DESLOCAMENTO FIXO E MÉTODO DE CONTROLE OPERACIONAL EM COMPRESSOR COM PISTçO DE DESLOCAMENTO FIXO. A passagem de introdução (31) da válvula giratória (35, 36) tem saídas (312, 313) para conduzir o fluido refrigerante em uma zona de pressão de sucção (142) até cada uma das câmaras de compressão (271, 281). Uma área de comutação no estado bloqueado isola a parte (142) da zona de pressão de sucção dentro do compressor (10) das saídas (312, 313) da passagem de introdução (31). A área de comutação inclui o corpo da válvula (42), a câmara de pressão de funcionamento (412) e a parte de aplicação da pressão de funcionamento (48, 67-68) A câmara de pressão de funcionamento (412) introduz uma pressão de funcionamento que é aplicada ao corpo da válvula (42) a fim de colocar o corpo da válvula (42) em uma posição de comunicação. A pressão na zona de pressão de sucção (142) age contra a pressao na câmara de pressão de funcionamento (412) através do corpo da válvula (42). Figura selecíonada Fíg. 1.
