FIELD: machine building.
SUBSTANCE: invention elates to field of automation and relates to gas-discharge compressor plants. Particular method is achieved that in parallel steps of compressor it is installed the device, controlling compression ratio (relative pressure boost), and is implemented by means of device - restraint of compression ratio, value of compression ratio in which is built into construction.
EFFECT: automation of compressor operation at charging of consumers and non-admission of operation with exceeding of compression ratio, that is in emergency state.
