    • A scroll compressor incorporates an electric motor unit and a scroll compressor unit in a sealed container. The scroll compressor unit has a frame having a bearing at the center thereof, a first scroll driven by the electric motor unit having an end plate and a wrap of an involute curve projecting from the end plate, and a second scroll having an end plate and a wrap of an involute curve projecting from the end plate of the second scroll provided in a juxtaposed relation with the first scroll so that the wraps of the two scrolls are fitted closely together to form a plurality of compression spaces. A driving device rotates the second scroll in the same direction as the first scroll. The driving device has a driving pin disposed on an outer circumference of either the first or second scroll and a guide groove extending in a radial direction of the other of the first or second scroll for receiving the driving pin in such a manner that a circle orbit of an outer circumference of the guide groove is located outside a circle orbit of a center of the driving pin. By this construction, the first scroll driven by the electric motor unit and the second scroll in confronting engagement with the first scroll are rotated in the same direction by a single driving device for compression.

    • There is disclosed a multi-stage compressing refrigeration device for multi-stage compressing a refrigerant using a plurality of compressing means. Its object is to enhance reliability, intend to reduce input and improve refrigeration effect, and to enhance efficiency. In the multi-stage compressing refrigeration device, low-stage compressing means and high-stage compressing means, a condenser, first expanding means, an intermediate evaporator, second expanding means and a main evaporator constitute a refrigeration cycle. The refrigerant flowing out of the condenser is branched into one refrigerant passed to the intermediate evaporator via the first expanding means and the other refrigerant passed to the main evaporator via the second expanding means. Heat exchange is performed between the refrigerant flowing into the second expanding means and the intermediate evaporator. Additionally, the refrigerant flowing out of the main evaporator is sucked by the low-stage compressing means, and the refrigerant flowing out of the intermediate evaporator is sucked by the high-stage compressing means together with the refrigerant discharged from the low-stage compressing means.
    • 公开了一种使用多个压缩装置对制冷剂进行多级压缩的多级压缩式制冷装置。 其目的是提高可靠性,打算减少投入,提高制冷效果,提高效率。 在多级压缩制冷装置中,低级压缩装置和高级压缩装置,冷凝器,第一膨胀装置,中间蒸发器,第二膨胀装置和主蒸发器构成制冷循环。 从冷凝器流出的制冷剂经由第一膨胀装置分支成一个传递到中间蒸发器的制冷剂,另一个制冷剂经由第二膨胀装置传递到主蒸发器。 在流入第二膨胀装置的制冷剂和中间蒸发器之间进行热交换。 此外,从主蒸发器流出的制冷剂被低级压缩装置吸入,从中间蒸发器流出的制冷剂与从低级压缩装置排出的制冷剂一起被高级压缩装置吸入 。
