The invention provides a compressor and a refrigerator, the compressor comprises a first chamber, a second chamber and a sliding groove communicated with the first chamber and the second chamber, the first chamber is internally provided with a piston, the piston is matched with the first chamber, the second chamber is internally provided with a roller, the sliding groove is internally provided with a sliding sheet, and the sliding sheet is matched with the first chamber. The two ends of the sliding piece are connected with the piston and the roller correspondingly, and the sliding piece and the roller are matched to divide the second cavity into an air suction cavity and a compression cavity. The gas which enters the first cavity and is subjected to primary compression is fed into the second cavity to be subjected to secondary compression, or the gas which enters the second cavity and is subjected to primary compression is fed into the first cavity to be subjected to secondary compression. According to the co
