To provide a variable capacity swash plate type compressor capable of reducing the number of components in a discharge muffler chamber and the number of work processes, reducing the pulsating pressure (pulsating noise) of discharged refrigerant, setting a check valve without increasing the size of the compressor, preventing superposing of a pulsation pressure waveform, and preventing coming-out of the check valve.
This variable capacity swash plate type compressor comprises: a cylinder block; a front housing; a driving shaft; a plurality of pistons performing a reciprocating motion inside the cylinder bore; a rear housing coupled to the rear of the cylinder block and having a suction chamber and a discharge chamber formed therein in such a manner as to be partitioned from each other by a partitioning wall, the discharge chamber having the discharge muffler chamber partitioned and formed by a division wall to reduce a pulsating pressure of the discharged refrigerant; and a check valve coupled to the inner side of the division wall to allow circulation of the refrigerant inside the compressor and prevent a backflow of the refrigerant when an air conditioner is turned off.
