APPARATUS FOR CONTROLLING PHASE IN PULSE TUBE REFRIGERATOR AND PULSE TUBE REFRIGERATOR

摘要

The present invention relates to a phase control apparatus for a pulse tube refrigerator and a pulse tube refrigerator. The phase control apparatus for a pulse tube refrigerator, according to the present invention, comprises a cylinder, a piston, a spring, and a gas storage, thereby controlling flow resistance as an independent variable by controlling one or more from the weight of the piston, the stiffness of the spring, the volume of an inner space, the diameter of the piston, the gap between the piston and the cylinder, the diameter of an orifice hole, and the number of the orifice holes.
