する自動圧力制御装置。 A self-adjusting valve that self-adjusts the pressure of the supplied fluid to a preset pressure, a set pressure changing means that changes the set pressure of the self-adjusting valve, and a fluid pressure of the self-adjusting valve to be controlled. A control unit that controls the set pressure changing means so that the set pressure of the self-regulating valve becomes the changed set pressure based on the output of the pressure detecting means when changing the set pressure. An automatic pressure control device comprising:
