摘要: A rotary valve unit which reduces the torque required to turn the valve disc, and the amount of wear dust that is blown into the cold head, using differential gas forces to keep the valve disc in contact with the valve seat, and which enables larger diameter valve discs to be utilized for multi-ported pulse tubes that have less force on the face of the valve disc, resulting in reduced torque and reduced wear rate.

摘要: An improved method of reducing wear dust and torque required to turn a multi-port rotary disc valve utilizes a thrust bearing to hold the valve seat and/or valve disc such that they are not in contact with each other, or have light contact each other.

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.
