A refrigerant cycle system includes a condenser having a condensation portion for condensing refrigerant discharged from a compressor, and a receiver for separating refrigerant from the condensation portion into gas refrigerant and liquid refrigerant, and for storing the liquid refrigerant. In this system, refrigerant from the condensation portion flows into the receiver through a first communication hole, and liquid refrigerant in the receiver is discharged through a second communication hole in which a pressure loss is generated. Further, gas refrigerant at an upper side in the receiver is discharged to a downstream side of the second communication hole through a gas bypass pipe.

The apparatus defined in claim 1 wherein the leveling means comprise a roller having opposite ends, a rotary axis extending between said ends axis and a conical surface, and mounting means for mounting the roller at said roller axis above the rotary surface so that said conical surface is parallel to the rotary surface and defines a gap therewith. 7. The apparatus defined in claim 6, wherein the roller comprises a rigid conical core, and an elastomeric covering on said core and which constitutes said conical surface. 8. The apparatus defined in claim 7 wherein said elastomeric covering includes a pair of circular elastomeric ridges at the opposite ends of said roller which contact said rotary surface and maintain the conical surface of the roller at a selected distance from the rotary surface so as to establish said gap. 9. The apparatus defined in claim 8 and further including means for moving the roller closer to said rotary surface so that said ridges are compressed to an extent that said conical surface contacts the rotary surface. 10. The apparatus defined in claim 2, wherein the scraping means comprise a channel supported above the rotary surface, a liner in the channel and facing the rotary surface, and said liner having opposite walls defining between them an alley which extends over the rotary surface and one of said walls having an edge constituting said scraping edge, and said pushing means comprise a movable scraper slidable along said alley and means for moving the scraper along said alley between a retracted position relatively close to said central axis and an extended position relatively close to said cylinder. 11. The apparatus defined in claim 10, wherein the scraper is shaped to close said window when the scraper is in said extended position. 12. The apparatus defined in claim 11 wherein said one liner wall and its said scraping edge are movable relative to said channel, and biasing means are operative between said one liner wall and said channel to bias the scraping edge toward the rotary surface. 13. The apparatus defined in claim 12 wherein said one liner wall and the channel have opposing surfaces and the biasing means include a resilient strip sandwiched between said opposing surfaces. 14. The apparatus defined in claim 2 wherein the ejection means comprise a piston having an end facing said bottom opening and being moveable within the forming cylinder; an ejection member mounted to said piston end, and means for moving the piston between a first position which locates the ejection member above said window and a second position which locates the ejection member below said window adjacent to said bottom opening. 15. The apparatus defined in claim 14 wherein the ejection member includes a cup with a concave wall facing the bottom opening of the cylinder; an elastomeric covering on said concave wall to define an interior space, and a passage extending from said interior space to a location outside the cup. 16. The apparatus defined in claim 15 wherein said covering normally spans the concave wall so that it is substantially parallel to the bottom opening of the cylinder. 17. The apparatus defined in claim 15 wherein said covering normally follows the contour of said concave wall, and further including means for introducing a fluid through said passage into said interior space so as to deform the diaphragm so that it substantially spans said concave wall. 18. The apparatus defined in claim 16 wherein said covering stretches when extended. 19. The apparatus defined in claim 1 or 2 as further including means for cooling the rotary surface to a temperature low enough to at least partially freeze the liquid product mix deposited on said rotary surface to from a frozen product body. 20. Apparatus for dispensing a food product comprising a rotary surface having a central axis and a periphery; motive means for rotating the rotary surface about said axis; depositing means spaced above the rotary surface for depositing a selected amount of liquid product mix on the rotary surface while that is rotating so that the liquid product mix spreads out on the rotary surface and sets to form a thin, at least partially solidified product body, said depositing means including a first supply of first product base; a first aeration nozzle having first and second inlet ports and an outlet port; a hose connecting the first supply to the first inlet port so as to deliver first product base to said first nozzle; means for conducting compressed gas to the second inlet port so that a first product base/gas mixture can issue from said outlet port, and conduit means extending from said outlet port to a location above the rotary surface so that said mixture constitutes said selected amount of liquid product and is delivered from said conduit means to the rotary surface; product delivery means disposed between the depositing means and the rotary surface, said delivery means including scraping means supported above the rotary surface and having a working edge engaging the rotary surface while said rotary surface is rotating to scrape the at least partially solidified product body into a ridge row, and removing means for removing said ridge row from the rotary surface as said food product. 21. The apparatus defined in claim 20 wherein the conduit means comprise a passage leading from said outlet port to a location over said rotary surface and having a length and diameter such that the passage produces confined turbulent mixing of said mixture whereby the liquid product is delivered to the rotary surface with a selected amount of aeration. 22. The apparatus defined in claim 21 wherein said passage is two to four feet long. 23. The apparatus defined in claim 22 wherein said passage is about three feet long. 24. The apparatus defined in claim 21, further including a second supply of said product base; a second aeration nozzle similar to the first nozzle; a second hose connecting the second supply to the first inlet port of the second nozzle so as to deliver second product base to the second nozzle and means for conducting compressed gas to the second inlet port of the second nozzle so that a second product base/gas mixture can issue from the outlet port of the second nozzle to said conduit means in lieu of the first product base/gas mixture from the first nozzle. 25. Apparatus for dispensing a food product comprising a substantially horizontal rotary surface having a central axis and a periphery; a motor for rotating the rotary surface about said axis; a depositing device spaced above the rotary surface for depositing a selected amount of liquid product mix on the rotary surface while said rotary surface is rotating so that the liquid product mix spreads out on the rotary surface and sets to form a thin, at least partially solidified product body; a scraper supported above the rotary surface and having a working edge engaging the rotary surface while said rotary surface is rotating to scrape said at least partially solidified product body into a ridge row on the rotary surface; a removing device for removing said ridge row from the rotary surface to form said food product, and a leveler spaced above the rotary surface to establish a gap therewith, said leveler being positioned ahead of the scraper so as to level the liquid product mix on said rotary surface while said rotary surface is rotating to the height of said gap prior to the formation of said at least partially solidified product body. 26. Apparatus for dispensing a food product comprising a substantially horizontal rotary surface having a central axis and a periphery; a motor for rotating the rotary surface about
