Abstract

PURPOSE: To enable to set a pressure easily to be operated bases upon the load conditions of a reciprocating type compressor, by achieving accurate control for keeping a constant pressure by effecting a positive ON-OFF control of unloader valves at a predetermined period, and changing the ratio ON-OFF time of the unloader valves according to the discharge pressure of the compressor.
CONSTITUTION: In the compressor shown in the Fig, an air pipe of a pressure signal system is extended from a receiver tank 10 and connected to a pressure transmitter 18 via a valve 11, and an electric pressure signal b is transmitted from the transmitter 18 to a pressure control unit 20. On the other hand, an electric signal from a pressure instructing setter 19 is afforded also to the pressure control unit 20 as a pressure instruction a. The pressure control unit 20 thus furnished with the above two input signals a, b gives a signal instructing an appropriate ratio of ON-OFF time to unloader valve 2, 3 for unloading the valves 2, 3 positively at a predetermined period. Therefore, it is enabled to achieve an accurate constant-pressure control that has not been attained by the conventional art.
