PROBLEM TO BE SOLVED: To properly displace a vane partitioning a compression chamber in a cylinder rotation-type compressor.SOLUTION: First pins 261a projecting in an axial direction, are disposed on both end portions of a first vane 23a partitioning a first compression chamber Va formed between an inner peripheral face of a first rotor 22a and an outer peripheral face of a cylinder 21. Further the first pins 261a are fitted to side plates closing axial both end portions of a region defining the first compression chamber Va of the cylinder 21, and guide grooves 252c for restricting the displacement of the first pins 261a are formed. Here, the guide grooves 252c are formed into the circular arc shape, so that the first vane 23a is properly displaced to bring an end portion at an outer peripheral side of the first vane 23a into contact with an inner peripheral face of the cylinder 21.SELECTED DRAWING: Figure 6 |
