Full-closed-operating miniature rolling rotor refrigeration compressor

The utility model discloses a full-closed-operating miniature rolling rotor refrigeration compressor which comprises a cylinder, an upper flange, a lower flange, a rolling piston, an exhaust partition, blades and a motor, wherein the upper flange and the lower flange are fixedly connected through a crankshaft main journal and the cylinder to constitute a complete compression pump; the motor and the compression pump are tightly sheathed on the shell to constitute a compressor; a rotor of the motor is tightly connected with the extension section of the crankshaft installed in a bearing hole of the upper flange; and the lower flange is provided with an exhaust valve mounting groove, a cambered exhaust groove and a circular resonance groove. By merging the two exhaust structures of the existing compressor, the utility model can effectively overcome the defect that lubricating oil is discharged along with gas; and an exhaust silencing chamber formed by hermetically installing the exhaust groove of the lower flange
