Abstract: PURPOSE:To effectively reduce the noise of a compressor while preventing heat accumulation by forming a soundproof space between a sealed container and an outer container provided in such a manner as surrounding the outside of the sealed container, and filling the soundproof space with a heat transfer fluid. CONSTITUTION:Two circular elastic members 4 of roughly the same bore as the outside diameter of the center portion of the shell of a sealed container 1 are fitted with each other while being separated from each other by a predetermined distance, at the shell portion of the center of the sealed container 1 wherein a compressor which is driven and rotated via a crank shaft 4 by a motor element consisting of a stator 2 and a rotor 3 is installed, and an outer container 15 having an inner surface separated from the sealed container 1 by approximately the wall thickness thereof is provided in such a manner as covering the whole sealed container 1. A soundproof space 16 is thereby defined between the sealed container 1 and the outer container 15 over the whole peripheries of the containers and the soundproof space 16 is filled with a heat transfer fluid (e.g. a fluid sealer, oil). The outer container 15 comprises a center tubular portion 15a and lid-shaped portions 15b, 15c on both sides.

Abstract: PURPOSE:To moderate required accuracy of the bore of the insert hole of an oil pipe so as to ease processing, and to enable the oil pipe to be certainly fitted by fitting the oil pipe to the crank part by using an abundant radial margin of a spring pin. CONSTITUTION:An insert hole 26 for a spring pin 24 is formed on the upper end part of an oil pipe 21 made of plastic or the like. First, one end of the spring pin 24 is pressingly inserted into the insert hole 27 of the lower end part of the crank part 6 of a cranks shaft 5. And, then, the oil pipe 21 is fitted by pressingly inserting the other end part of the pin 24, into the spring pin insert hole 26.
