参见图3和图4，在本发明的实施例中，涡旋盘2还包括：在端板21的第二表面212上形成的环形凹部2120，第一油孔部分51从所述环形凹部2120沿远离涡旋盘2的旋转轴线的方向延伸并与所述环形凹部2120连通。参见图2至图4，涡旋盘2还包括：从端板21的第二表面212伸出的毂部23，所述毂部23具有内孔230，所述环形凹部2120围绕所述毂部23。油孔5还可以包括：第三油孔部分，所述第三油孔部分从所述毂部23的内孔230沿远离涡旋盘2的旋转轴线的方向延伸到所述环形凹部2120，以将所述毂部23的内孔230与所述环形凹部2120连通。
在图3和图4所示的实施例中，第一油孔部分51沿相对于涡旋盘2的旋转轴线倾斜的平面延伸，而第二油孔部分52沿平行于涡旋盘2的旋转轴线的方向延伸。参见图3和图4，在本发明的实施例中，在采用多个油孔5的情况下，多个第一油孔部分51可以分别沿对应的平面延伸，或沿同一个圆锥面延伸。或者，第一油孔部分51可以沿垂直于涡旋盘2的旋转轴线的平面延伸，而第二油孔部分52沿平行于涡旋盘2的旋转轴线的方向延伸。显然，第二油孔部分52只要从第一油孔部分51在端板21和涡旋卷22中延伸到涡旋卷22的远离端板21的带状表面220即可，而不限于沿特定的方向延伸。作为示例，第一油孔部分51沿涡旋盘2的径向方向延伸，或者在平行于涡旋盘2的旋转轴线的方向观看时，第一油孔部分51沿涡旋盘2的径向方向延伸。
参见图2至图4，在本发明的实施例中，油孔5是多个油孔5，所述多个油孔5中的第一油孔5A的所述第二油孔部分52的开口50位于涡旋卷22的带状表面220的外端部2201，而所述多个油孔5中的第二油孔5B的所述第二油孔部分52的开口50与所述多个油孔5中的第一油孔5A的所述第二油孔部分52的开口50间隔175至185度的角度，例如间隔180度的角度，即，两个开口50的中心线大致位于通过涡旋盘2的旋转轴线的平面上。在图中所示的实施例中，两个油孔5的第一油孔部分51、第二油孔部分52和开口50的中心线大致位于通过涡旋盘2的旋转轴线的平面上。在平行于涡旋盘2的旋转轴线的方向观看时，带状表面220具有靠近涡旋盘2的旋转轴线的内端部和远离涡旋盘2的旋转轴线的外端部2201。在仅仅设置一个油孔5的情况下，所述第二油孔部分52的开口50位于涡旋卷22的带状表面220的外端部2201，或者所述第二油孔部分52的开口50与涡旋卷22的带状表面220的外端部2201间隔175至185度的角度，例如间隔180度的角度。
参见图2至图4，在本发明的实施例中，涡旋盘2还包括：位于所述涡旋卷22的带状表面220中的带状凹槽221，带状凹槽221中可以放置密封件。所述第二油孔部分52的开口50位于所述带状凹槽221的外侧。更具体而言，所述多个油孔5中的第一油孔5A的所述第二油孔部分52的开口50在涡旋卷22的周向方向上位于所述带状凹槽221的外端部2210的外侧，并且所述多个油孔5中的第二油孔5B的所述第二油孔部分52的开口50在涡旋卷22的径向方向上位于所述带状凹槽221的外侧。在仅仅设置一个油孔5的情况下，所述第二油孔部分52的开口50在涡旋卷22的周向方向上位于所述带状凹槽221的外端部2210的外侧，或者所述第二油孔部分52的开口50在涡旋卷22的径向方向上位于所述带状凹槽221的外侧。
需要说明的是，尽管在图中第一油孔部分51在端板21的外周面具有开口，实际上仅仅是为了方便加工第一油孔部分51，在形成第一油孔部分51之后，第一油孔部分51在端板21的外周面的开口将用堵头等零件堵塞。
当压缩机运行时，润滑油首先从油池由泵泵送到涡旋盘2的毂部23，在离心力的作用下，润滑油进入油孔5，并在涡旋卷22的末端的开口50流出，由此可以降低润滑油循环率和排出制冷剂的温度。
根据本发明的实施例的涡旋压缩机，通过采用根据本发明的实施例的油孔5，可以改善涡旋压缩机的性能。例如，可以最小化对制冷剂的过热影响，以及最小化压缩期间的润滑油的泄露，降低润滑油循环率和排出制冷剂的温度。通过降低润滑油循环率和润滑油的泄露可以提高质量流量和能效比
根据本发明的实施例的涡旋压缩机，通过采用根据本发明的实施例的油孔5，有助于提高润滑能力，降低涡旋卷之间的磨损；有助于涡旋卷之间更好地密封。此外能够抑制在压缩腔中的压缩的制冷剂的温度升高。
尽管描述了上述实施例，但是上述实施例中的一些特征可以进行组合形成新的实施例。
