ABSTRACT:
A control system for producing first and second fluid sources whose pressure difference is regulated to a desired value in response to four fluid supplies of independently variable pressures. The pressure of the first fluid source is not allowed to decrease substantially below the third fluid supply pressure or rise substantially higher than the desired value above the pressure of the third fluid supply. The pressure of the second fluid source is not allowed to rise substantially above the fourth fluid supply pressure or decrease substantially lower than the desired value below the pressure of the third fluid supply. The system may consist of a diaphragm-type pressure regulator which is responsive to the difference in pressure of the two fluid sources. One side of the regulator is selectively valved to connect to one of two pressure supplies while the other side is selectively valved to connect to one of two additional pressure supplies.
