当压缩机100运行时，参见图1，电机7通过驱动件3驱动第一涡旋盘11旋转，且第一涡旋盘11驱动第二涡旋盘12旋转。制冷剂通过入口82进入壳体101的第一壳体1011和第二壳体1012形成的密封空间，一部分制冷剂向上流动，绕过筒形挡板83的上端，然后向下流动，通过流体通道6的流体入口61进入流体通道6(参见图4、图6至图8、图10、图14、图15)，另一部分制冷剂向下流动，在筒形挡板83的下端的下方，进入电机7，以冷却电机，然后向上流动，通过流体通道6的流体入口61进入流体通道6。全部制冷剂经由吸入腔88，进入第二涡旋卷124和第一涡旋卷113形成的压缩腔，压缩后的制冷剂通过出口84排出。参见图4、图6至图8、图10，如果流体通道6相对于驱动件3的轴向方向倾斜延伸，则通过流体通道6的流体入口61进入流体通道6的制冷剂由于离心力而经受一级压缩，然后经由吸入腔88，进入第二涡旋卷124和第一涡旋卷113形成的压缩腔而经受二级压缩。同时，第二涡旋盘12带动设置在固定轴5的轴向内孔50中的上油螺栓81旋转，将容纳在壳体101的第一壳体1011底部的油槽中的润滑油抽吸到固定轴5的轴向内孔50中，第一部分润滑油，通过固定轴5上的横向通孔85(例如径向通孔)流到第二轴承52以及驱动件3的毂部31的第二端部312和支架4的凸缘部42(参见图1)之间。第二部分润滑油进入第二涡旋盘12的毂部121与第三轴承53之间的间隙以对第三轴承53进行润滑，进入第二涡旋盘12的毂部121与第三轴承53之间的间隙的一部分润滑 油进入第二涡旋盘12的第二端板123与驱动件3的凸缘部32之间的间隙，最后通过流体通道6进入第一涡旋盘11与第二涡旋盘12形成的空间，以对第一涡旋盘11与第二涡旋盘12进行润滑。进入第二涡旋盘12的毂部121与第三轴承53之间的间隙的另一部分润滑油绕过第三轴承53的上端部分进入第一轴承51，并且部分进入形成在固定轴5中的回油通道862，然后通过连通孔89进入形成在固定轴5中的回油通道861，最后回到在壳体101的第一壳体1011底部的油槽中。进入第一轴承51的润滑油通过横向通孔87(例如径向通孔)进入回油通道862，然后通过连通孔89进入回油通道861，最后回到在壳体101的第一壳体1011底部的油槽中。
根据本发明的实施例的涡旋压缩机，由于第一涡旋盘和第二涡旋盘各自围绕自己的旋转轴共同旋转，提高了压缩效率。另外，可以采用轴向磁通电动机，可以使电机的轴向尺寸更小，由此使压缩机结构更紧凑。此外，由于驱动件的结构设计，可以由驱动件驱动第一涡旋盘旋转，而第一涡旋盘驱动第二涡旋盘旋转，从而可以进一步地将所有轴承都设置在压缩机的同一侧，比如第二涡旋盘的在第一方向D1上的同一侧，从而可以进一步使压缩机结构紧凑。并且，驱动件3的驱动件设计，可以使得涡旋压缩机具有二级压缩。
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。
