Scroll compressor

The invention provides a scroll compressor. A scroll compressor is provided with a fixed scroll and an orbiting scroll. At least one of the fixed substrate and the rotary substrate has a sub-discharge port and a groove. The groove is partially covered by a spiral wall facing the groove so that the compression chamber communicating with the sub-discharge port, the other compression chambers during compression, and the compression chamber communicating with the main discharge port do not communicate with each other. And the groove is always communicated with any compression chamber. 本公开提供涡旋型压缩机。涡旋型压缩机具备固定涡盘以及回转涡盘。固定基板以及回转基板中的至少一方基板具有副喷出端口和槽。槽由与该槽对置的螺旋壁覆盖一部分，以使得不将与副喷出端口连通的压缩室，与压缩中途的其他压缩室以及和主喷出端口连通的压缩室连通。槽总是与任一个压缩室连通。
