Abstract: The present invention relates to an air foil journal bearing including a bump foil having a plurality of elastic bumps and provided and coupled inside a bearing housing, a mid-foil provided inside the bump foil, formed in a circumferential direction, and having at least one circumferential end coupled to the bearing housing, and a top foil provided inside the mid-foil, formed in the circumferential direction, and having at least one circumferential end coupled to the bearing housing, in which a stepped portion is formed as a radius of an inner peripheral surface of a partial circumferential region of the mid-foil is smaller than a radius of an inner peripheral surface of the remaining region, such that an additional pressure is generated in a section in which a maximum positive pressure is applied when a rotor rotates at low speed, such that the rotor may float at a relatively low rotational speed, and friction and vibration between the rotor and the top foil may be reduced.

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.
