DISPLACER VALVE FOR A CRYOGENIC REFRIGERATOR

WIPO Patent Application WO/2011/105684

A2

The present invention relates to a displacer valve for a cryogenic refrigerator, which is fastened to an annular side of a displacer cover by means of a bolt, and which opens/shuts a hole formed at the side of the displacer cover. The display valve comprises an anti-rotation guide fastened to an eccentric portion of the displacer cover by means of a bolt so as to prevent the displacer valve from rotating about the bolt that fastens the displacer valve. According to the present invention, the displacer valve is prevented from rotating about the bolt and deviating from a predetermined position, thus ensuring the operating reliability of the displacer valve.
