FIELD: mechanical engineering; compressors. SUBSTANCE: compressor has cylinder, drive slider-crank mechanism with drive shaft provided with eccentric and piston with noncontact seal and additional drive shaft with eccentric rotating at a speed of main drive shaft but in opposite direction, radii of both eccentrics being equal. Axes of shafts are either parallel to each other or coincide and intersect axis of cylinder at right angle. Additional drive shaft can be connected with main drive shaft through idler gear. Both drive shafts are furnished with counterweights which can be combined with gears installed on the same shafts. EFFECT: enlarged operating capabilities. 6 cl, 5 dwg
