Abstract
A refrigerator includes a working space which is in fluid communication with a vessel of the volume-variable type with a capillary acting as a flow resistance. Each time change of the average cycle pressure in the working space is occurs, the volume of the vessel is varied so as to cancel the pressure-change. Thus, the average cycle pressure in the working space may be kept at a set value.
