Abstract (en)
A scroll compressor is provided with a fixed scroll 5 and an orbiting scroll 6 meshed with each other to form a compression room 11, the fixed scroll having a release port 5e with a discharge outlet formed toward the central part and causing the compression room and the discharge side to communicate with each other on the outer circumferential side and a release valve 5a for preventing a reverse flow from the discharge side toward the compression room, and on the outer circumferential side of the fixed scroll a suction room 10 and a suction passage 5h. Further in the fixed scroll, a bypass passage 5f that causes the discharge side to communicate with the suction room or the suction passage is formed, and a bypass valve 14 for opening and closing the bypass passage is provided. Farther upstream than the suction room or the suction passage into which the bypass passage opens, a suction non-return valve 15 to prevent flowing back to the upstream side is disposed. In this way, highly efficient capacity control can be realized even under a light load operating condition by improving the delay in the discharge of the refrigerant to the discharge side when capacity-controlled operation is switched over to normal operation.
