FIELD: machine building.SUBSTANCE: compressor comprises an electric motor, a pressure chamber, a switch set in the electric motor control circuit, an adjusting screw. The compressor is additionally equipped by a baffler-fairing 19 of spherical shape on the side of supplying pipe branches connected to the lines of an air duct 3, gas duct 7 and spark plug 5. The baffler-fairing 19 is fixed by adjusting screws 20, 21 spring-loaded on the side of the valves 24, 25 of the first compression stage of the chamber 1. The latter is connected to the second compression chamber 2 by a pipe branch 27. The volume of the second compression chamber 2 is at least 2 volumes of the first compression stage of the chamber 1. An inlet valve 24 is a shutdown member of the pipe branch 27. The second compression chamber 2 is connected to a receiver 28 by a pipeline. The receiver 28 is pneumatically connected to a vane pump 46 and via a gas distributor 32 - to the consumer.EFFECT: increasing efficiency and reducing surges at high pressures of the gas being pumped.3 cl, 5 dwg |
