Abstract:
A discharge pulsation damping apparatus of a compressor including a housing therein, a compression mechanism for sucking a compressive fluid from outside, compressing said compressive fluid and discharging it to a discharge chamber defined inside said housing, a flow passage for guiding said compressive fluid inside said discharge chamber to the outside of said compressor, a discharge muffler region defined at an intermediate part of said flow passage inside said housing, a discharge pulsation damping apparatus of said compressor characterized in that a partition is disposed inside said discharge muffler region in such a manner as to divide said discharge muffler region into a first muffler chamber constituting a part of said flow passage and a second muffler chamber communicated with said first muffler chamber through a communication passage and independent of said flow passage, and feedback means is disposed for feeding back a fluid supplied into said second muffler chamber, while being carried by said compressive fluid and condensed inside said second muffler chamber, into said first muffler chamber.
