摘要： A rotary disc valve unit and refrigerators containing a rotary disc valve unit that has multiple valves, in which at least one rotary valve has ports connecting to the regenerator and at least one rotary valve has ports connecting to the warm ends of one or more pulse tubes where the rotary valve with ports for the regenerator has lighter contact than the rotary valve with ports for the pulse tubes. The valve face is divided into an inner area with ports for the pulse tubes and an outer area with ports for the regenerator, the inner area having a greater sealing pressure than the outer area.
