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.

轴密封组件(11)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)的外壁弹性变形。 因此,第一密封构件(21)的唇部受到使唇部抵抗旋转轴(15)的力减弱的张力。 因此,密封组件(11)提高了唇部的耐久性,并且保持了唇部的令人满意的特性,以跟随旋转轴(15)同时移动。
