摘要： A capacity controllable compressor apparatus has a plurality of high-pressure chamber compressors which are connected in parallel to a common refrigerant suction pipe and a common refrigerant discharge pipe, and oil equalizing pipes through which oil sumps of the plurality of compressors are communicated with each other. One of the plurality of compressors is operated with its chamber kept at a higher internal pressure than other compressors. The compressor apparatus comprises an oil separator disposed to the common discharge pipe; device for returning lubricating oil separated by the oil separator to a suction side of one of the compressors operated with its chamber kept at a higher internal pressure; first control device disposed in the oil equalizing pipes so as to prevent the lubricating oil from flowing into one of the two compressors communicated with each other by the oil equalizing pipe, said one being made inoperative when the capacity of the compressor apparatus is controlled; and valve device disposed in a discharge pipe of the inoperative compressor so as to prevent refrigerant from flowing into the inoperative compressor.

摘要： A scroll compressor comprising a housing, a frame, a fixed scroll and an orbiting scroll, arranged in the housing. Each of the fixed and orbiting scrolls have an end plate and a spiral wrap. A bearing boss is formed on the back surface of the end plate of said orbiting scroll. A plurality of radial ribs are formed on the back surface of the end plate of said orbiting scroll, with the radial ribs extending from the bearing boss to the marginal side of the end plate of said orbiting scroll.

摘要： In a scroll compressor having a stationary scroll and a revolving scroll, and a refrigerator incorporating this scroll compressor, the stationary scroll has a gas suction hole formed in its radially outer portion, a gas discharge hole formed in its central portion, and gas injection holes and a liquid injection hole formed between the suction and discharge holes. The gas injection holes are formed in a radially outer portion of the stationary scroll, and the liquid injection hole are formed in a central portion of the stationary scroll. The refrigerator incorporates the scroll compressor, a condenser, decompressors and an evaporator to form a refrigerating circuit. The liquid injection hole of the scroll compressor is directly connected by piping to the outlet of the condenser, and the gas injection holes are connected by piping to the outlet of the condenser through one of the decompressors. Even though the compressor is a single-stage compressor having one compression unit and one electric motor unit, the reduction in the volumetric efficiency can be limited and the power necessary for compression during practical use is substantially the same as the power for the two-stage compression type. Consequently, the compressor of the invention has substantially the same compressor efficiency as the conventional two-stage compressor at evaporation temperatures of -45.degree. to -70.degree. C.
摘要翻译：在具有静涡旋盘和旋转涡旋盘的涡旋式压缩机和构成该涡旋压缩机的冰箱中，固定涡旋盘具有形成在其径向外侧的气体吸入孔，形成在其中央部的气体排出孔，气体喷射孔以及形成在吸入孔和排出孔之间的液体喷射孔。气体注入孔形成在固定涡旋件的径向外侧部分，液体喷射孔形成在固定涡卷的中心部分。冰箱包括涡旋压缩机，冷凝器，减压器和蒸发器，以形成制冷回路。涡旋压缩机的液体注入孔通过管道直接连接到冷凝器的出口，并且气体注入孔通过管道通过减压器之一通过管道连接到冷凝器的出口。即使压缩机是具有一个压缩单元和一个电动机单元的单级压缩机，也可以限制体积效率的降低，并且在实际使用中压缩所需的功率与两级的功率基本相同压缩类型。因此，在-45〜-70℃的蒸发温度下，本发明的压缩机具有与传统的两级压缩机基本相同的压缩机效率。
