Abstract
A balance weight to equilibrate an inertial force due to reciprocation of an Oldham's ring is mounted so that a vibration due to an unbalanced inertial force of the Oldham's ring is transmitted in a direction perpendicular to or almost perpendicular to a connecting direction between the closed vessel and the accumulator, whereby a vibration resulting from an unbalanced inertial force of the compressor body due to the balance weight to equilibrate the inertial force on account of the reciprocation of the Oldham's ring is increased in a direction perpendicular to or almost perpendicular to the connecting direction between the closed vessel and the accumulator. The vibration, however, is reduced in the connecting direction or in a direction close to the connecting direction. As a result, vibrations of pipes connecting the closed vessel to the accumulator are reduced, and reduction of noise of the overall air conditioning system is attained.
