摘要： PROBLEM TO BE SOLVED: To sufficiently lubricate both an electric motor and a compressor part, in a compressor such as a scroll type compressor in which the electric motor is incorporated into inside of a closed housing.
SOLUTION: The electric motor 2 is provided in an upper part of the closed housing 1, and the compressor 1 is provided in a lower part of the closed housing 1. When the compressor part is a scroll type compressor, a back pressure chamber containing an opening 15 of a partition wall 9 is formed on an upper face of an end plate part 21 of a turning scroll 20. Lubricating oil included in discharged fluid is separated by for example, an oil separator 34, and supplied to the back pressure chamber through a lubricating oil passage 40 after moderately decompressed by a throttle element 37. The back pressure chamber also serves as a storage part of the lubricating oil. By rotation of a centrifugal type impeller 61 provided on an upper end part of a rotating shaft 6, the lubricating oil is lifted through a communication hole 60 formed on the rotating shaft 6 and discharged to inside of an upper part space 13. The lubricating oil is flowed down by gravity, lubricates each part and is stored in the back pressure chamber again.

摘要： PROBLEM TO BE SOLVED: To surely reduce consumption power of a compressor in a vapor compression type refrigerator. SOLUTION: The expander 4 and the compressor 1 are connected through a one-way clutch 6.Thereby, the number of rotations of the expander 4 is less than that of the compressor 1, and transmission of the power is automatically blocked when the expander 4 applies braking force to the compressor. Therefore, it is possible to prevent the expander 4 from applying braking force to the compressor 1, and to prevent the power consumption of the compressor 1, i.e., the power consumption of a motor 2, from increasing.

摘要： PROBLEM TO BE SOLVED: To prevent a motor and a compressor section from being overheated with the flow of lubricating oil by sufficiently lubricating both of them, in a scroll type compressor having the built-in motor. SOLUTION: This scroll type compressor comprises a motor 2 in the upper part of a sealed housing 1 and the scroll type compressor section 3 in the lower part. A back pressure chamber including an opening 15 of a partition wall 9 is formed on the upper surface of an end plate section 21 of a turning scroll 20. The lubricating oil contained in the fluid pressurized and delivered to a deliver chamber 32 is separated by an oil separator 34, and accumulates in an oil storage section 36 in a delivering pressure applying state. The accumulating lubricating oil is pressed up and released to an upper space 13 through a throttle element 37 and an oil feeding pipe 38 by the pressure of itself without using a pump or the like, is made to flow down by gravity, lubricates the inside of the motor 2 and a bearing, and then accumulates in the back pressure chamber.

摘要： PROBLEM TO BE SOLVED: To create adequate back pressure at all times independently of a change in operating conditions.
SOLUTION: As a pressure control means for a back pressure chamber 19, a pressure introduction hole 16 communicated with the back pressure chamber 19 is opened to an area between a rotary scroll 6 and a fixed scroll 8 where a cavity therebetween is reduced with pressure rise in the back pressure chamber 19. A communication passage is provided for communicating a high pressure part such as an operation chamber 11 with the back pressure chamber 19 and the pressure introduction hole 16 is opened to the midway thereof, as a restriction means whose flow path area is reduced with the approach of both scrolls 6, 8. Thus, the supply of high pressure fluid to the back pressure 19 is restricted by the pressure introduction hole 16 closed with the approach of both scrolls 6, 8, to suppress the rise of the back pressure with no strong thrust. On the contrary, when a space between both scrolls 6, 8 is larger, the flow path area to the pressure introduction hole 16 is enlarged to increase the supply of the high pressure fluid to the back pressure chamber 19, preventing the strong slide contact of the rotary scroll 6 with a housing 1.

摘要翻译：要解决的问题：独立于操作条件的变化，始终创造足够的背压。解决方案：作为背压室19的压力控制装置，与背压室19连通的压力导入孔16向旋转涡旋件6与固定涡旋件8之间的空间开口，在背压室19中压力升高。连通通道用于将诸如操作室11的高压部分与背压室19连通，并且压力引入孔16在其中途打开，作为限制装置其流路面积随着两个涡卷6,8的接近而减小。因此，高压流体对背压19的供给受到两个涡卷6,8接近的压力引入孔16的限制，以抑制背压的上升没有强劲的推力。相反，当两个涡卷6,8之间的空间较大时，加压导入孔16的流路面积被扩大，从而增加了对背压室19的高压流体的供给，防止了强力滑动接触具有壳体1的旋转涡卷6。版权所有（C）2005，JPO＆NCIPI
