Refrigerating compressor

A refrigerating compressor comprising:

• a compressing element;
• and
• a hermetic container that accommodates the compressing element,
• wherein the compressing element includes
• a compressing chamber where refrigerant gas is to be compressed, and
• a suction muffler that communicates with the compressing chamber, the suction muffler having a sound deadening space formed therein,
• wherein the suction muffler includes
• a tail tube having a first end which opens into the hermetic container and a second end which opens directly into the sound deadening space, a diameter of the sound deadening space being larger than a diameter of the second end of the tail tube, the tail tube being arranged such that the second end of the tail tube protrudes into and is surrounded by the sound deadening space,
• an expansion chamber arranged within the sound deadening space, and
• a resonating chamber formed outside of the expansion chamber and attached to the tail tube, the resonating chamber having a resonance frequency agreeing substantially with a specific resonance frequency of the hermetic container,
• wherein the tail tube is arranged to suck the refrigerant gas into the resonating chamber along an L-shaped path, and the resonating chamber is formed on an extension line of an axis of the tail tube such that the resonating chamber has an opening arranged to face the sound deadening space in a direction in which refrigerant gas is to flow toward the second end of the tail tube, and such that the resonating chamber extends from the opening of the resonating chamber and away from the sound deadening space,
• wherein the resonating chamber and the tail tube are in communication with each other at a communicating section which does not include a throttle portion, and wherein the resonating chamber is arranged entirely within the suction muffler.
