PURPOSE: A compressor is provided to control refrigerant output using a ball member moved by outputted refrigerant pressure in order to reduce compressor operation noise. CONSTITUTION: A compressor comprises a shell(110), a first compression device(130), a second compression device(140), a first bearing(160), a second bearing(170), a connecting member, and a valve apparatus. The shell forms an enclosure. The first compression device is installed in the shell and compresses refrigerant. The second compression device compresses the refrigerant with the first compression device simultaneously or recompresses the pressed refrigerant by the first compression device. The first bearing receives the refrigerant, which is compressed in the first compression device and outputted to the shell. The first bearing comprises a connection port to discharge the refrigerant to the shell. The second bearing comprises a first refrigerant discharge port and a second refrigerant discharge port. The connecting member connects to the connection port and the second refrigerant discharge port and the refrigerant outputted to the shell circulates in the connecting member. The valve apparatus discharges the refrigerant in the shell only in case that a refrigerant pressure from the first bearing is over a set pressure. |
