The invention provides a compressor air cylinder and a compressor comprising the same. The compressor air cylinder comprises an air cylinder body and a circumferential side wall formed on the outer edge of the air cylinder body; the side wall comprises a circumferential part extending upwards from the outer edge of the upper end face of the air cylinder body or/and a circumferential part extending downwards from the outer edge of the lower end face of the air cylinder body; the air cylinder body is provided with an air cylinder body working cavity penetrating through the upper end face and the lower end face of the air cylinder body; and an air suction channel is arranged in the radial direction of the air cylinder body, one end of the air suction channel is an air suction port, and the other end of the air suction channel communicates with the air cylinder body working cavity. According to the compressor air cylinder, through the integrated design of the air cylinder body and a shell, the height of the compressor is reduced while the height of the air cylinder body is reduced, the structure is compact, and the higher miniaturization requirement is met; and meanwhile, the air suction channel directly arranged at the position of the air cylinder body can effectively solve the problem of internal leakage, air inlet loss is reduced, the degree of superheat is reduced, and therefore the operation stability and efficiency of the compressor are improved.
