Abstract

PURPOSE: To facilitate a variation of the secondary pressure in response to a dies etc. in a neumatic pressure regulator in a press machine by a method wherein a secondary pressure and the predetremined value are compared with each other by a comparator means and then a change-over valve is controlled in response to a result of this comparison operation.
CONSTITUTION: Secondary pressure is detected by a pressure sensor 9 installed in the tank, and the sensed value is compared with the predetermined value in the comparator means 12, 12'... Relays X1, X2... are operated in response to the result of the comparison, the solenoid coils SV-A, SV-B for the solenoid operated change- over valve 8 are properly energized so as to control the change-over valve 8. During this operation, when the secondary pressure is higher than the predetermined value, the secondary pressure at the tank is discharged by the change-over valve 8 so as to decrease the secondary pressure, and in turn when the secondary pressure is lower than the predetermined value, the change-over valve 8 is operated so as to communicate the primary air with the secondary air, resulting in making the secondary air increased in its value, then the secondary pressure is always detected and adjusted to be in a range of the predetermined value.
