Air compressor

The utility model relates to the technical field of automobile accessories, in particular to an air compressor. The air compressor comprises a cooling oil duct, the cooling oil duct is arranged in the air compressor, and lubricating oil can circulate in the cooling oil duct. According to the technical scheme, the cooling oil duct is arranged in the air compressor, lubricating oil can circulate in the cooling oil duct, and the lubricating oil absorbs and takes away heat in the air compressor so as to cool the air compressor. According to the air compressor, the problem that the cooling oil duct is possibly damaged by other parts is solved, the structure of the cooling oil duct is effectively protected, the service life of the cooling oil duct is prolonged, the maintenance problem caused by damage of the oil duct is reduced, and the later maintenance cost of the air compressor is reduced. 本实用新型涉及汽车配件技术领域，具体为一种空气压缩机。空气压缩机包括冷却油道，冷却油道排布于空气压缩机内部，冷却油道内可流通润滑油。采用排布于空气压缩机内部冷却油道，冷却油道内可流通润滑油，润滑油吸收并带走空气压缩机内部热量进而对空气压缩机进行冷却
