Abstract:
A rotary valve mechanism of a cryocooler includes a valve rotor and a valve stator. A rotor recessed portion is formed such that the rotor recessed portion fluidally communicates with a stator recessed portion at a first opening degree at a second phase of a valve rotation. The valve rotor includes a first rotor communication groove and/or a second rotor communication groove formed in the valve rotor such that the rotor recessed portion fluidally communicates with the stator recessed portion at an opening degree which is smaller than the first opening degree at a first phase preceding the second phase, and/or the valve stator includes a stator communication path formed in the valve stator such that the rotor recessed portion fluidally communicates with the stator recessed portion at an opening degree which is smaller than the first opening degree at the first phase preceding the second phase.

Claim (Index 6):
A rotary valve mechanism of a cryocooler, the mechanism comprising:\n a valve stator which includes a stator plane perpendicular to a valve rotation axis and a stator recessed portion which is open to the stator plane and is a portion of a working gas flow path of a cryocooler; and a valve rotor which includes a rotor plane which is perpendicular to the valve rotation axis and is in surface-contact with the stator plane, and a rotor recessed portion which is open to the rotor plane and is a portion of the working gas flow path of the cryocooler, wherein the valve rotor is disposed so as to rotate around the valve rotation axis with respect to the valve stator, wherein the rotor recessed portion is formed in the valve rotor such that the rotor recessed portion fluidally communicates with the stator recessed portion at a first opening degree at a second phase of a valve rotation, wherein the valve rotor includes a rotor communication path which is formed in the valve rotor such that the rotor recessed portion fluidally communicates with the stator recessed portion at an opening degree which is smaller than the first opening degree at a first phase of the valve rotation preceding the second phase, and/or wherein the valve stator includes a stator communication path which is formed in the valve stator such that the rotor recessed portion fluidally communicates with the stator recessed portion at an opening degree which is smaller than the first opening degree at the first phase of the valve rotation preceding the second phase.
