Abstract
In a Stirling cycle refrigerator, or in a method for controlling the operation of a Stirling cycle refrigerator, when it starts or stops being operated, or according to the detection result from position or temperature detecting means, the voltage supplied to a driving power source for driving a piston is controlled appropriately to prevent the piston from moving too far out of its movable range and thereby prevent breakage of a component resulting from collision between the piston and a displacer.
