摘要： PROBLEM TO BE SOLVED: To provide a compressor carrying out miniaturization by omitting a buffer and capable of simplifying piping by reducing connection points between members.SOLUTION: A first accumulator 110 is connected to an upstream of a first compression element 2A, and a second accumulator 210 is connected to an upstream of a second compression element 2B. A switching mechanism 160 switching between an operating state and a non-operating state of the second compression element 2B is connected to an upstream of the second accumulator 210. By this, it is not necessary to install a buffer provided between an accumulator and the second compression element in a conventional compressor.

摘要： PROBLEM TO BE SOLVED: To provide a compressor whose size can be reduced by reducing buffers as other components while preventing supercharging loss, and in which piping can be simplified by reducing pipes to be connected to the buffers.SOLUTION: At a compressing operation position of a valve element 164, a second port P2 is communicated with an internal space 164a of the valve element 164 and a first port P1 and a third port P3 are communicated with each other via an internal space 163a of a valve box 163 for compressing operation of a second compression element. Thus, the internal space 163a of the valve box 163 can be served as a buffer because the internal space 163a of the valve box 163 is larger, when low pressure fluid is introduced from the upstream side of a first compression element into the internal space 163a of the valve box 163.
摘要翻译：要解决的问题：提供一种压缩机，其压缩机的尺寸可以通过减少缓冲器作为其它部件而减少，同时防止增压损失，并且其中可以通过减少要连接到缓冲器的管道来简化管道。解决方案：在阀元件164的压缩操作位置处，第二端口P2与阀元件164的内部空间164a连通，并且第一端口P1和第三端口P3经由内部用于压缩第二压缩元件的操作的阀箱163的空间163a。因此，当低压流体从第一压缩元件的上游侧引入到内部空间163a中时，阀箱163的内部空间163a可以用作缓冲器，因为阀箱163的内部空间163a较大。（C）2012年，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To improve an operating efficiency of a peak-cut operation by a method wherein a useless work of a compressor is reduced so as to reduce an input of the compressor when a cooling operation is carried out under utilization of storage of cold heat. SOLUTION: A main refrigerant circuit 101 comprised of a scroll compressor 1, a four-way changing-over valve 2, an outdoor heat exchanger 3, an electrical expansion valve 4 and indoor heat exchangers 6, 6... is provided with a circuit 102 utilizing storage of heat having an accumulated heat exchanger 8. A heat accumulation circuit 20 provided with a heat storage tank 22 is connected to the storage heat exchanger 8. The compressor 1 is provided with a bypass passage 57 for bypassing refrigerant gas during its compression stroke. The bypass passage 57 is provided with a check valve 56 for allowing only the refrigerant flow to be flowed only in such a direction as one in which the refrigerant is discharged during the compression stroke. In the case that a condensing pressure is low, the check valve 56 is opened, compression is carried out under a low compression ratio and the refrigerant flows in both discharging pipe 53 and the bypass passage 57.

摘要： PROBLEM TO BE SOLVED: To effectively separate the oil from the discharge gas, and to miniaturize a compressor by fitting a partitioning wall member, which forms a part of an oil separating means, to a discharge pipe side of a fitting part to be fitted to an inner surface of a casing of a bearing support member in the condition that it is overlapped with a gas collision plate in the axial direction of a crank shaft. SOLUTION: During the operation of a scroll compressor, the discharge coolant gas at a high pressure is moved from a left side to a right side of an upper part inside of a casing 1 through a fixed scroll 10, a support housing 12, each upper part of stator 7a of an electric motor 7 and each gas passage 44 in the condition that the lubricating oil of a compression chamber 16 is mixed. Flow velocity of the discharge coolant gas at the time of passing through each gas injection hole 50 of a left oil separating plate 46 as a partitioning wall member is increased so as to collide with a right oil separation plate 47 as a gas collision plate. At this stage, the lubricating oil mixed in the coolant gas is separated from the discharge coolant gas, and the lubricating oil, which is not separated at this stage, is dropped to an oil reservoir by dead weight thereof so as to be separated from the discharge coolant gas.

摘要： PURPOSE:To carry out the proper oil supply suitable for each operation condition of low or high speed by connecting a decompression mechanism and an oil feeding pipe having a flow rate control valve between an oil reservoir and a suction passage of a scroll. CONSTITUTION:A decompression mechanism 6 and an oil feeding pipe 8 having a flow rate control valve 7 which is controlled to a large opening degree at a low speed and to a small opening degree at a high speed are connected between an oil reservoir 10 and a suction passages 5 of scrolls 2 and 3. A relatively large quantity of oil can be supplied into the scrolls 2 and 3 from the oil feeding pipe 8 by controlling the flow rate control valve 7 to a large opening degree at a low speed, and the oil feed compensation on a sliding surface can be carried out. In the case of high speed, the flow rate control valve 7 is controlled to a small opening degree, and the excessive oil feed is suppressed, and the oil feed in proper quantity is carried out. Accordingly, the proper oil feed suitable for each operation condition of low or high speed can be carried out.
