摘要： Disclosed are a self-pressure-relief air distribution mechanism and a corresponding cryogenic refrigerator. The self-pressure-relief air distribution mechanism includes an air distribution valve (6) and a rotary valve (7), where a rear face of the air distribution valve (6) is divided into a high-pressure face (66) and a low-pressure face (65), and the high-pressure face (66) and the low-pressure face (65) are hermetically separated by a third sealing ring (b3) that seals the air distribution valve (6) and a cover (2); and the air distribution valve (6) is provided with a pressure-relief hole (61) that axially penetrates an air distribution face (64) and the low-pressure face (65) of the air distribution valve (6), and a low-pressure passage (22) of the cover (2) can communicate with the rear face of the air distribution valve (6) via the pressure-relief hole (61), to guide a low-pressure airflow in the cover (2) to the rear face of the air distribution valve (6). The cryogenic refrigerator includes the self-pressure-relief air distribution mechanism. With the provision of the pressure-relief hole (61) and the third sealing ring (b3), the self-pressure-relief air distribution mechanism has a reduced pressure receiving area, thereby reducing a positive acting force and reducing wear.
