Abstract (en)

[origin: EP3569862A1] A co-rotating scroll compressor includes a driving-side scroll member (70) that is rotationally driven by a driving unit and includes a spiral driving-side wall (71b) disposed on a driving-side end plate (71a), and a driven-side scroll member that includes a driven-side wall corresponding to the driving-side wall (71b), the driven-side wall being disposed on a driven-side end plate and engaging with the driving-side wall (71b) to form a compression chamber. Positioning pins (40) that position a phase of the driving-side scroll member (70) around a driving-side rotation axis (CL1) are provided at two positions around the driving-side rotation axis (CL1) at a front end of the driving-side wall (71b) in an axis direction, and dummy pins (41) that are provided at equal angular intervals around the driving-side rotation axis (CL1) with the positioning pins (40) are provided.
