摘要：
The present invention discloses a displacer valve for a cryogenic refrigerator, which is mounted on one circular surface of a displacer cover by a bolt to open and close a hole formed in the surface of the displacer cover. The displacer valve includes a rotation preventing guide fastened to an eccentric portion of the displacer cover by the bolt to prevent the displacer valve from rotating around the bolt. Therefore, the displacer valve does not rotate around the bolt but is fixed in a proper position, so that its operational reliability can be ensured.
