Abstract:

PURPOSE: To keep a resonance in the vertical directions with respect to an axis away from a specified frequency range and improve the property of the compressor against noise by a method wherein a metallic body is attached to a straight tube extending into an accumulator, in the device in which the accumulator is attached to an enclosed vessel.

CONSTITUTION: The accumulator 5 is attached to the outer periphery of the enclosed vessel 1 and the straight tube 8, connected to the suction port 2a of a compression element 2, is extended into the accumulator 5. A cylindrical metallic body is provided at the tip end of the straight tube 8 by a proper means such as force fitting or the like. According to this method, the resonance of the straight tube 8 in the vertical directions with respect to the axis thereof may be adjusted in the specified frequency range and the property of the compressor against noise may be improved.
