FIELD: machine building.
SUBSTANCE: system consists of at least two parallel arranged ejectors. Additionally and parallel to ejectors there is installed a control valve of main for overflow of active fluid medium. The main of low pressure gas is connected to inputs of the ejectors; the main of high pressure fluid medium is connected to inputs of the ejectors and the control valve via a gate valve. Outputs of the ejectors are connected to an output main via the gate valves; the output of the said control valve is coupled with the output main in case of implementation of gaseous high pressure fluid medium, and with the main of high pressure fluid medium by means of the pump in case of implementation of fluid high pressure medium.
EFFECT: raised efficiency of system operation.
