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.
Claims9
A refrigerator comprising:
- an expansion chamber;
- a compression chamber operatively connected to said expansion chamber to form a working space;
- a vessel connected to said working space and having a variable volume for storming therein a working medium under a pressure balanced to the average cycle pressure in said working space;
- and
- capillary means for providing a flow restriction between said working space and said vessel
- wherein said vessel comprises a bellows arrangement defining a closed space.
