摘要： A reciprocating compressor of un-lubricating type, equipped with a cooling device including a cooling fan beneath a motor and provided with four gas compressors, each having a cylinder and a piston. The pistons of each gas compressor cooperate by converting a rotating motion of a crankpin of a crankshaft provided on an electric drive source via two yokes having a phase difference of 90 degrees therebetween to a reciprocating motion by a scotch yoke mechanism. The flows of compressed gases from each gas compressor are joined to one place by connecting tubes to be discharged. The lengths of each connecting tube are selected such that pressure waves of the compressed gases compete with each other at the joining point for a time period encompassing one rotation of the crankpin, whereby a pulsation resulting from gas flow discharged in concentration is decreased.
