FIELD: gas lines; mechanical engineering. SUBSTANCE: compressor machine for transportation of gas is driven by drive engine. Machine is provided with suction and delivery pipe lines. Heat exchanger provided with safety valve is connected to lubrication system pipe line by line to be cooled. Cooling line of heat exchanger connects it in parallel with suction pipe line by means of inlet and outlet pipe lines of gas cooler. Unit is also provided with additional heat exchanger fitted with safety valve which is connected in parallel with main heat exchanger. Cooled lines of heat exchangers are provided with pressure sensors and automatic overpressure protective systems. Metering and locking valves are connected in series to cooled line of heat exchangers. Valves operate automatically. Hydraulic seals are mounted in delivery and return pipe lines of lubrication system between housing of unit and heat exchangers. Hydraulic seals work on lubricant-and-coolant. Gas separator is connected to return pipe line. Unit is provided with fuel system. EFFECT: enhanced reliability. 4 cl, 1 dwg
