Exhaust structure of double ring type rotary compressor cylinder, which is characterized in that the two circular cylinder shell on the outer side of the cover plate are respectively fixedly connected with a circular cover plate with the same shape of annular sealing plate, sealing plate and the movable cover plate sealing contact in the movable cover two piston transport to the intersection the front end, are respectively provided with a guide groove, the guide groove through both sides of the movable cover plate, side through the compression chamber, the exhaust side can be on-off seal plate mouth; are respectively provided with a left axial exhaust port and the exhaust port is located at the intersection of right axial sealing plate on the two. The conducting groove has the appearance of a long strip shape, and is arranged on a ring-shaped movable cover plate between the front face and the front end face of the piston, and is close to the front face of the piston running direction. The design of the gas cylinder compression process is closed, compressed to a certain pressure and outlet exhaust vent conduction, do not set the exhaust valve of the compressor to obtain higher efficiency, lower noise, more stable work.
