    • A refrigerating system including a refrigeration circuit and a scroll type compressor provided with two volume control mechanisms to allow the system to selectively perform full load operation and unloaded operation. The scroll type compressor includes two scroll members of known construction meshing with each other to define compression chambers and a suction chamber and is combined with the refrigeration circuit having an outdoor heat exchanger, an expansion valve, an indoor heat exchanger and a four-way change-over valve to provide a heat pump type refrigerating system. The volume control mechanisms each include a pair of bypass apertures in the fixed scroll member communicating with a valve chamber having a valve member slidably mounted therein and normally biased to an open position by a spring. The bypass apertures, of which one communicates with the suction chamber and the other communicates with one of the compression chambers, and the valve chamber constitute a bypass passageway. A pressure introducing pipe opens in the valve chamber. Upward movement of the valve member brings the two bypass apertures in communication with each other through the valve chamber to enable the system to perform a volume control operation. In another application, four volume control mechanisms are located symmetrically and divided into two blocks through a flow passage switching device to assign two mechanisms to one block. By this arrangement, the system is able to perform volume control operation in three stages, or able to operate selectively at maximum load, intermediate load and minimum load.
    • 一种制冷系统,包括制冷回路和涡旋式压缩机,该压缩机设置有两个容积控制机构,以允许系统选择性地执行满载操作和卸载操作。 涡旋式压缩机包括两个已知构造的涡旋构件,其彼此啮合以限定压缩室和吸入室,并与具有室外热交换器,膨胀阀,室内热交换器和四通变换的制冷回路组合 提供一种热泵式制冷系统。 音量控制机构各自包括在固定涡旋构件中的一对旁通孔,其与具有可滑动地安装在其中的阀构件的阀室连通,并且通过弹簧通常偏压到打开位置。 旁通孔与吸入室连通,另一个与一个压缩室连通,并且阀室构成旁路通路。 压力引入管在阀室中打开。 阀构件的向上运动使两个旁通孔通过阀室彼此连通,以使系统能够执行体积控制操作。 在另一个应用中,四个音量控制机构被对称地定位并且通过流路切换装置分成两个块,以将两个机构分配给一个块。 通过这种安排,该系统能够在三个阶段进行音量控制操作,或能够在最大负载,中间负载和最小负载下选择性地进行操作。
