Compressor

The utility model relates to the technical field of compressors, and discloses a compressor which comprises a main shaft, a rotor, a stator and an oil cup which are arranged in a shell, the rotor and the stator are respectively arranged on the main shaft in a penetrating mode, the rotor is fixedly connected with the main shaft so as to drive the main shaft to rotate under driving of the stator, the oil cup comprises a main body, a first blade and a second blade, and the main body is used for being connected with the main shaft. The first blade and the second blade are arranged on the two sides of the main body respectively, the ratio h1/A of the maximum folding height h1 of the first blade relative to the main body to the displacement A of the compressor is larger than or equal to 0.15, and the ratio h2/A of the maximum folding height h2 of the second blade relative to the main body to A is larger than or equal to 0.15. According to the compressor, the structural design of the oil cup is optimized, refrigerat
