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 1):
A cryocooler comprising:\n a motor; a displacer which is engaged to the motor so as to be reciprocated by the motor; an expander airtight container in which the displacer is accommodated and a gas expansion chamber is formed between the displacer and the expander airtight container, wherein the expander airtight container includes a low-pressure gas chamber which communicates with a compressor intake port; a valve stator which includes a stator plane perpendicular to a valve rotation axis, a high-pressure gas inflow port which is open to the stator plane and communicates with a compressor discharge port, and a stator recessed portion which is open to the stator plane and communicates with the gas expansion chamber, wherein the valve stator is disposed in the low-pressure gas chamber; 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, a rotor recessed portion which is open to the rotor plane and communicates with the high-pressure gas inflow port, and a first rotor communication path which is open to the rotor plane and extends toward the rotor recessed portion, wherein the valve rotor is disposed in the low-pressure gas chamber 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 and the rotor recessed portion is fluidally separated from the stator recessed portion at a third phase of the valve rotation following the second phase, and wherein the first rotor communication path 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.
