ABSTRACT:
A refrigerator comprises a cold accumulator, an expansion chamber, a movable member which is provided in the expansion chamber, and which can move to change the inside volume of the expansion chamber, a compressed operating gas which is introduced into the expansion chamber through the cold accumulator, the gas being expanded under the action of the movable member to generate cold, and being exhausted from the expansion chamber through the cold accumulator, an auxiliary expansion chamber which communicates with the expansion chamber through a narrow flow passage, and an auxiliary movable member which is associated with the movable member, and which can be provided in the auxiliary chamber to change the inside volume of the auxiliary expansion chamber.
