<p>[PROBLEMS] A load control system that highly accurately controls pressure of a pneumatic apparatus and can quickly cope with a pressure variation. [MEANS FOR SOLVING PROBLEMS] A pressure regulation screw (61) for setting a secondary pressure of a pressure regulation apparatus body (60), which supplies compressed air as a secondary pressure to a pneumatic cylinder device (10), is connected to a motor shaft (42) of a rotation drive device (41) through bowl-shaped members (51, 52) having flexibility in a direction to approach and separate from each other. A drive control circuit (30), having received a pressure signal outputted from a pressure sensor (14a) of the pneumatic cylinder device (10), pivotally drives the pressure regulation screw (61) through the motor shaft (42) of the rotation drive device (41) and the bowl-shaped members (51, 52) so that the pressure signal maintains a set value.</p> |
