The process of air suction, compression and discharge can be realized in the process that the motor rotor drives the piston loudness and the cylinder body of the air cylinder to do reciprocating motion. When the air reaches a certain time through the air suction port or the air suction pipe of the shell, the exhaust valve is opened, and the high-pressure air is exhausted out of the shell of the compressor through the inner exhaust pipe.
The compressor is suitable to adopt the present disclosure to ensure the axial elastic support of the piston and simultaneously have higher radial support effect. In addition, the equivalent mass of the compressor piston can be reduced, and the requirements of high frequency and low resonance mass of the air-conditioning linear compressor are met.
