FIELD: mechanical engineering; compressors.
SUBSTANCE: proposed piston compressor contains at least one cylinder with delivery and suction valves. Piston with guide drive slider-crank mechanism has strap with two parallel slots in which drive eccentrics are fitted provided with counterweights and drive pins in antiphase relative to each other and connected with drive shafts. Longitudinal axes of both parallel slots are on one line perpendicular to axis of cylinder. Line connecting axes of drive shafts and perpendicular to said axes is parallel to longitudinal axes of slots. Strap of drive slider-crank mechanism can be made sectional, with one part connected with piston and other part arranged from first one along cylinder axis through distance equal to width of parallel slots, being connected with first part through inserts whose thickness is equal to width of parallel slots.
EFFECT: increased service life of compressor, reduced vibration loads.
