Abstract: A buffered rotary valve is provided to supply buffering pressure from a buffer to a refrigerating machine between high and low pressure supply from a compressor, thereby reducing unnecessary supply of working fluid. A buffered rotary valve includes a pressure vessel(110) formed with a high pressure port(111) and a low pressure port(112) in an outer surface to be connected to an inlet port and an outlet port of a compressor respectively, wherein a plurality of pulsation pressure ports(113) are formed at a lower part to be connected to with a refrigerating machine. A valve head(130) is connected to a driving motor(115) mounted in the pressure vessel to rotate by the driving motor. A valve seat(120) is formed at a lower end of the valve head for transferring high pressure and low pressure alternately according to the rotation of the valve head. A buffer(160) is mounted at an outer periphery of the valve seat for supplying buffering pressure to the refrigerating machine between the high pressure and the low pressure.
