Scroll compressor

The utility model relates to a scroll compressor. The bedplate portion of swing vortex spare has a pressure route, and this pressure route is the radial the most inboard side room intercommunication of being located in bellying exterior space and a plurality of compression chambers, when the reversal operation of motor, the refrigerant gaseous from bellying exterior space via the pressure route and mobile to side room in, advance the fuel feeding of menstruation by the fuel feeding route because of bellying exterior space's pressure decrease. In addition, have a pressure route check valve mechanism in the pressure route, this pressure route check valve mechanism allow refrigerant gaseous from bellying exterior space orientation in side room flow to prevent the gaseous reversed flow of refrigerant. 本实用新型涉及种涡旋式压缩机。摆动涡旋件的座板部具有压力路径，该压力路径将凸起部外部空间与多个压缩室中的位于径向最内侧的最内侧室连通，在电动机的反转运转时，制冷剂气体从凸起部外部空间经由压力路径而向最内侧室流动，因凸起部外部空间的压力降低而进行经由供油路径的供油。另外，在压力路径具有压力路径止回阀机构，该压力路径止回阀机构允许制冷剂气体从凸起部外部空间朝向最内侧室流动，并阻止制冷剂气体的反向流动。
