    • A compressor (100) with a built-in expander comprises a closed container (1) in which an oil is stored at the bottom, a compressing mechanism (2) or an expanding mechanism (3) disposed at the inside upper part of the closed container (1), an expanding mechanism (3) or a compressing mechanism (2) disposed at the inside lower part of the closed container (1), a shaft (5) for connecting the compressing mechanism (2) to the expanding mechanism (3), and an oil pump (6) for supplying the oil (26) with which the space around the expanding mechanism (3) is filled to the compressing mechanism (2). The compressor (100) is characterized in that the oil pump (6) is disposed between the compressing mechanism (2) and the expanding mechanism (3). Since the oil is supplied to the mechanism positioned in the upper space without passing through the mechanism positioned at the lower space, heat transfer between the expanding mechanism (3) and the compressing mechanism (2) can be reduced.
    • 具有内置膨胀机的压缩机(100)包括:密封容器(1),其中储存有油的封闭容器(1),压缩机构(2)或膨胀机构(3),其设置在封闭的内部上部 容器(1),设置在密闭容器(1)的内下部的膨胀机构(3)或压缩机构(2),用于将压缩机构(2)连接到膨胀机构 3),以及用于将膨胀机构(3)周围的空间填充到压缩机构(2)的油(26)的油泵(6)。 压缩机(100)的特征在于,油压泵(6)设置在压缩机构(2)和膨胀机构(3)之间。 由于在不通过位于下部空间的机构的情况下将油供给到位于上部空间的机构,因此可以减小膨胀机构(3)与压缩机构(2)之间的热传递。
