摘要：To provide a rotary valve mechanism contributing to preventing an increa in the size of a driving motor of a cryogenic refrigeration machine.SOLUTION: The rotary valve mechanism of the cryogenic refrigeration machine includes a valve rotor 34a and a valve stator 34b. A rotor recesd part 68 is formed in the valve rotor 34a so that the rotor recesd part 68 is fluidally communicated with a stator recesd part 64 at a first opening in a cond pha of valve rotation. The valve rotor 34a includes a first rotor communication groove 80 and/or a cond rotor communication groove 82 which is formed in the valve rotor 34a so that the rotor recesd part 68 is fluidally communicated with the stator recesd part 64 at an opening smaller than the first opening in a first pha of the valve rotation preceding the cond pha, and/or the valve stator 34b includes a stator communication path which is formed in the valve stator 34b so that the rotor recesd part 68 is fluidally communicated with the stator recesd part 64 at an opening smaller than the first opening in the first pha of the valve rotation preceding the cond pha.SELECTED DRAWING: Figure 2
