Abstract
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 these 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.
Claims3
A refrigerant compressor, comprising:
- a piston;
- a cylinder housing the piston;
- a valve plate, which has a first suction hole and a second suction hole, provided at an opening end of the cylinder;
- a first suction reed valve, which opens and closes the first suction hole, provided between the opening end of the cylinder and the valve plate;
- and
- a second suction reed valve, which opens and closes the second suction hole and has a natural frequency different from that of the first reed valve, provided between the opening end of the cylinder and the valve plate.
