Abstract

PURPOSE: To reduce the fluctuation in the discharge pressure of the command discharge port of parallel-operated compressors or the like, by amplifying a signal corresponding to the discharge pressure detected at the common discharge port to indicate how much the discharge pressure is.
CONSTITUTION: When the quantity of compressed gas used by a machine decreases and the discharge pressure of the common discharge port rises, a pressure transmitter 2a produces an output proportional to the rise in the discharge pressure. The output is applied to an amplifier such as a controller 2b. The increase in the output is amplified enough to actuate a monitor switch 2c1. When the discharge pressure falls, another monitor switch 2c2 is surely actuated. A control unit 3 regulates the operation of the compressors C1WCn in connection with the action of the monitor switches 2c1, 2c2.
