Abstract (en)

[origin: EP1541868A1] A valve plate includes a plurality of suction holes and a plurality of suction reed valves for opening and closing them. At least two of theses suction reed valves have different natural frequencies. In this configuration, a natural frequency of one reed valve is larger. Therefore, even when an operation frequency is changed to a higher frequency, the compressor can suck a refrigerant gas into a cylinder efficiently without occurring delayed closing and reduction of a lift amount. Thus, refrigerating capacity and compression efficiency can be increased. <IMAGE>
