流体机械及具备其的制冷循环装置
摘要：
本发明提供一种流体机械及具备其的制冷循环装置。流体机械(10)具备：在底部形成油积存部(16)的密闭容器(11)；被供给在油积存部的上层部(16a)积存的油的主压缩机构(3)；旋转电动机(8)；连结主压缩机构(3)和旋转电动机(8)的主压缩机构用轴(38)；配置于比上层部(16a)低的位置，从工作流体回收动力的动力回收机构(5)；配置于比上层部(16a)低的位置的副压缩机构(2)；连结动力回收机构(5)和副压缩机构(2)的动力回收轴(16)；位于上层部(16a)和动力回收机构(5)之间，对油积存部(16)的上层部(16a)和配置有动力回收机构(5)的油积存部的下层部(16b)之间的油的流通加以限制的绝热构造(80)。
摘要（英）：

A fluid machine (10) includes: a closed casing (11) having an oil reservoir (16) in its bottom portion; a main compression mechanism (3) supplied with oil contained in an upper portion (16a) of the oil reservoir; a rotation motor (8); a main compression mechanism side shaft (38) for coupling the main compression mechanism (3) and the rotation motor (8); a mechanical power recovery mechanism (5) disposed below the upper portion (16a) and recovering mechanical power from a working fluid; a sub-compression mechanism (2) disposed below the upper portion (16a); a mechanical power recovery shaft (16) for coupling the mechanical power recovery mechanism (5) and the sub-compression mechanism (2); and a heat-insulating structure (80) located between the upper portion (16a) and the mechanical powerrecovery mechanism (5) and restricting flow of oil between the upper portion (16a) of the oil reservoir (16) and a lower portion (16b) of the oil reservoir in which the mechanical power recovery mechanism (5) is provided.
