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.

摘要： A Stirling refrigerator, which prevents oil rising, makes oil seal bellows have long-life, and includes a housing, cylinder, piston, piston rod and an oil seal bellows. The oil seal bellows seals a space between the housing and the cylinder, wherein a tip end of the oil seal bellows is sealed and fixed on the piston or on the piston rod inside the cylinder, and a base end of the oil seal bellows is installed on the housing. The oil seal bellows reciprocates with a stroke, wherein the tip end of the oil seal bellows is compressed to a compression side from a position of free length then returns to the position of free length.
