Abstract
The utility model particularly provides an air compressor with a small volume. The air compressor with the small volume comprises a shell body. A compressor chamber, an oil-gas separation device and an oil return pipe are arranged in the shell body in an adjacent mode, and the compressor is arranged in the compressor chamber. The compressor is connected with an air inlet, and a transmission shaft of the compressor is connected with a rotating shaft of a motor. The air compressor with the small volume has the advantages that the three parts are all arranged in the compressor, the structure is compact, the volume is small, quake-proof effect is good; and the oil return pipe is internally arranged, and the requirement for low-temperature work can be satisfied.
