摘要： A cryocooler includes an attachment flange including a refrigerant gas introduction port through which refrigerant gas is introduced into a recondensing chamber from an ambient temperature environment, and attachable to the recondensing chamber, and a cooling stage that is disposed inside the recondensing chamber when the attachment flange is attached to the recondensing chamber. The refrigerant gas introduction port is perpendicularly or obliquely oriented with respect to an axial direction of the cryocooler so that a refrigerant gas flow exiting the refrigerant gas introduction port deviates from the cooling stage.

摘要： In a cryogenic refrigerator, a displacer defines an internal space, and circulates a working fluid in the internal space. A cylinder houses the displacer such as to enable it to reciprocate, and, at an interval from the bottom side of the displacer, forms an expansion space for the working fluid. A cooling stage is provided along an outer circumferential and bottom portion of the cylinder, in a location corresponding to the expansion space. A heat exchanger is arranged inside the expansion space and is thermally connected to the cooling stage. An end portion of the displacer on its expansion-space side has an opening that serves as an entry/exit port between the internal space and the expansion space for the working fluid. A working-fluid flow channel connects the internal space and the expansion space via the heat exchanger.

摘要： In a cryocooler for developing coldness of 4 K or lower by expanding helium, an expander expands high-pressure helium. A compressor compresses low-pressure helium returned from the expander, to generate high-pressure helium, and supplies the high-pressure helium to the expander. When helium temperature in the expander is 2.17 K or lower, the pressure of the low-pressure helium is equal to or higher than pressure given by a curve, in a helium state diagram in which the horizontal axis is temperature and the vertical axis is pressure, along which helium's volumetric thermal expansion coefficient is 0.

摘要： A cryogenic refrigerator includes a displacer that is reciprocably mounted within a cylinder; a spool valve that is connected to the compressor and performs switching between an intake mode where a high-pressure refrigerant gas is supplied from the compressor to the cylinder and an exhaust mode where a low-pressure refrigerant gas within the cylinder is made to flow back to the compressor; and a drive unit that drives the spool valve. The spool valve has a valve body, and a drive rod that moves relative to the valve body and is integrated with the spool. The drive unit performs driving so that the magnitude of a speed when the drive rod moves from a top dead center to a bottom dead center is different from the magnitude of a speed when the drive rod moves from the bottom dead center to the top dead center, at the same displacement position.
