Abstract (en)
[origin: EP3388673A1] A scroll compressor is provided with: an annular thrust plate (32) provided within a housing and having a thrust bearing surface (32S) in contact with the rear surface of the end plate (21A) of an orbiting scroll (21); and a main balance weight (41) provided to a drive shaft (9) so as to be axially adjacent to the thrust plate (32) and cancelling centrifugal force caused by the eccentric orbiting movement of the orbiting scroll (21). The main balance weight (41) has a decreasing outer diameter section (41a) provided at the thrust plate (32)-side end of the main balance weight (41), the decreasing outer diameter section (41a) having an outer diameter gradually decreasing toward the thrust plate (32). The thrust plate (32) has an increasing inner diameter section (32a) on the main balance weight (41) side of the inner diameter section of the thrust plate (32), the increasing inner diameter section (32a) having an inner diameter gradually increasing toward the main balance weight (41). The decreasing outer diameter section (41a) and the increasing inner diameter section (32a) overlap each other in the radial direction and the axial direction.
