Zusammenfassung:	PCT No. PCT/FR98/00854 Sec. 371 Date Dec. 29, 1998 Sec. 102(e) Date Dec. 29, 1998 PCT Filed Apr. 28, 1998 PCT Pub. No. WO98/49502 PCT Pub. Date Nov. 5, 1998The invention concerns a refrigerating fluid cycle comprising the standard compressor, condenser, liquid/gas separating reservoir, expansion device and evaporator. The invention is characterized in that a pre-expansion device is placed between the condenser and the reservoir, so as to reduce the fluid pressure until it reaches its saturation vapor pressure. The reservoir can thus contain a variable amount of liquid to compensate the fluid losses in the cycle by maintaining the sub-cooling temperature constant thereby enabling the heat load to be absorbed by the condenser.
