In response to the signal a, a first control signal b for maintaining the pressure of the compressed gas at a fixed set pressure is output, and a part of the compressed gas is returned to the suction side of the compressor 11 by the bypass control valve 21. The pressure of the compressed gas is adjusted. At this time, since the second pressure controller 24 has not received the cutoff signal, the second control signal c is zero.

When the signal is closed and the closing signal is output, the second pressure controller 24 outputs the second control signal c corresponding to the cutoff of the consuming equipment. As described above, the second control signal c includes a plurality of consuming equipments 15,
16 and 17 and are set at least temporarily larger than the opening of the bypass control valve by the first control signal b, the first control signal b and the second control signal In the comparison of c, the control signal having the larger opening degree of the bypass control valve 21, that is, the second control signal c is output to the bypass control valve 21. Since the second control signal c is set so as to correspond to the opening degree of the bypass control valve necessary to suppress a rise in pressure when each of the consuming facilities 15, 16, 17 is shut off, Equipment 1
The bypass control valve is opened to a preset large opening at the same time as any one of 5, 16, and 17 is shut off, thereby preventing the pressure of the compressed gas from rising.

During this time, the first control signal b receives the output of the comparison controller 25 as the external feedback signal d and outputs a value calculated. Therefore, when the second control signal c decreases, the first control signal b controls the bypass control valve. 21 is controlled, and returns to the normal operation state in which the pressure is controlled to the set pressure.

Thus, the bypass control valve is always opened larger, and more compressed gas is returned to the suction side of the compressor. In particular, if the second control signal is made to correspond to each of the plurality of consuming equipment, and is set at least temporarily larger than the opening degree of the bypass control valve by the first control signal, when any of the consuming equipment is shut off, the Upon receiving the shut-off signal, the bypass control valve is instantaneously and greatly opened as compared with the first control valve to return more compressed gas to the suction side of the compressor, avoiding a sudden rise in the pressure of the compressed gas and other consumption.
