Abstract: The present invention relates to an apparatus for reducing suction pulsation and a swash plate type compressor comprising same. The apparatus for reducing suction pulsation, which is installed in a swash plate type compressor and can reduce suction pulsation of a refrigerant, comprises: a case formed in a hollow container shape and having a suction port with an open upper side in the height direction and discharge openings formed by opened areas in the side wall thereof; a core portion formed inside the case, between the suction port and the discharge openings so as to be movable in the height direction; a lever having a vertical portion extending upwardly, along the side wall of the case, from one end of a horizontal portion disposed in the vicinity of the bottom wall of the case and coupled to the case such that the portion where the horizontal portion and the vertical portion meet is rotatable about a horizontal axis; and an elastic means interposed between the core portion and the horizontal portion of the lever.
