Description

Compressor with a compressor body having a rotor with a rotor shaft Technical Field The utility model relates to the technical field of compressors, in particular to a compressor. Background When the compressor normally operates, the moving vortex plate changes the volume of the compression cavity in the revolution translation mode, the effect of compressing gas is achieved, in the process, the bearing of the moving vortex plate is extremely high in load and needs to be well lubricated, and otherwise the bearing of the moving vortex plate is easy to wear. Referring to fig. 1-2, in the related art, a lubrication method for a bearing of an orbiting scroll 2 'is to supply oil to the bearing of the orbiting scroll 2' by supplying the oil to a spindle head portion through a main shaft 1 'and discharging the oil from an oil supply passage 11' of the spindle head.
