Abstract

The present invention relates to a valve plate assembly of a compressor comprising: a valve plate in which a suction port is formed; and a suction reed which opens and closes the suction port, wherein , the suction port includes a first suction port located at the entrance and a second suction port located at the exit, and the area of ​​the second suction port is larger than that of the first suction port. Therefore, since the suction port including the first and second suction ports has a large area, an increase in flow velocity of the sucked refrigerant is prevented, thereby reducing a pressure drop of the sucked refrigerant.

Description

technical field [0001] The present invention relates to a valve plate assembly of a compressor, and more particularly, to a valve plate assembly of a compressor for increasing the area of ​​a suction port to prevent the flow rate of sucked refrigerant from increasing. Background technique [0002] Since the compressor included in the cooling system of the automobile air conditioner is directly connected to the engine through a belt, the number of revolutions of the compressor cannot be controlled. [0003] Therefore, at present, variable capacity compressors capable of obtaining cooling capacity by changing the discharge amount of refrigerant without being limited by the number of rotations of the engine are widely used. [0004] Various types of variable capacity compressors have been disclosed, such as swash plate type, rotary type, and scroll type. [0005] Here, in the swash plate type compressor, a swash plate provided in such a manner that an inclination angle changes...
