摘要： A shaft sealing assembly (11) seals a rotary shaft (15) of a refrigerant compressor with a first sealing member (21), which is a lip seal. The first sealing member (21) has a hollow portion. As the pressure in the interior space of the compressor housing (13) increases, an outer wall surrounding the hollow portion (51) is elastically deformed. Accordingly, a lip portion of the first sealing member (21) receives a tension that weakens a force pressing the lip portion against the rotary shaft (15). Therefore, the sealing assembly (11) improves the durability of the lip portion and maintains a satisfactory property of the lip portion to follow displacement of the rotary shaft (15) at the same time.
摘要翻译：轴密封组件（11）利用作为唇形密封件的第一密封构件（21）密封制冷剂压缩机的旋转轴（15）。第一密封构件（21）具有中空部分。随着压缩机壳体13的内部空间中的压力增加，围绕中空部分51的外壁发生弹性变形。因此，第一密封部件（21）的唇部受到减弱将唇部按压于旋转轴（15）的力的张力。因此，密封组件（11）提高了唇部的耐久性，并且保持了唇部随着旋转轴（15）的位移同时满意的令人满意的性能。

摘要： A shaft sealing assembly (26) is located in a suction chamber (19) of a swash plate type compressor to seal the space between a drive shaft (18) and a housing. A first end portion of the drive shaft (18) is supported by a first radial bearing (24). A second end portion of the drive shaft (18) is supported by a second radial bearing. The suction chamber (19) is closer to the first end portion of the drive shaft (18) than the first radial bearing (24) is. An axial passage (60) is formed in the drive shaft (18) to connect the suction chamber (19) to the crank chamber (17). An inlet (60a) of the axial passage (60) is closer to the second end portion than the second radial bearing is. An outlet (60b) of the axial passage (60) is closer to the second end portion than the first radial bearing (24) is.
摘要翻译：轴密封组件（26）位于旋转斜盘式压缩机的吸入室（19）中，以密封驱动轴（18）和壳体之间的空间。驱动轴（18）的第一端部由第一径向轴承（24）支撑。驱动轴（18）的第二端部由第二径向轴承支撑。吸入室（19）比第一径向轴承（24）更靠近驱动轴（18）的第一端部。轴向通道（60）形成在驱动轴（18）中，以将抽吸室（19）连接到曲柄室（17）。轴向通道（60）的入口（60a）比第二径向轴承更靠近第二端部。轴向通道（60）的出口（60b）比第一径向轴承（24）更靠近第二端部。
