Definitions
- FIGURE 1 is an elevational view partly in cross section of the refrigerating apparatus of the invention.
- FIGURE 2 is another elevational view partly in cross section illustrating another form of refrigeration apparatus.
- numeral 2 denotes a cylinder in which is mounted a displacer 4 which defines three volumes 3, 5 and 7. At one side of cylinder 2 is a cylinder body 6 in which is a displacer 8 defining volumes 9-11. Volume 9 connects with volume 5 through a passageway 10.
- a first rotary valve 12 has two ports 14 and 15. The valve may be driven by an electric motor or other suitable means. Port 16 is connected through conduit 18 to volume 3. Likewise, port 16 is connected through a conduit 20 and regenerator 22 to volume 11. Compressed gas, as helium, may be supplied from compressor 24 through ports 14 or 16 to volumes 3 and 11, depending on Whether high pressure slots 26 or low pressure slots 25 in valve 12 is in register with ports 14 and 16. Low pressure may be from 15 to 200 pounds per square inch and suitable high pressures may run from 200 to 500 pounds per square inch.
- Volume 5 is interconnected with volume 7 through heat exchanger 32 and thermal regenerator member 34 so that pressure in volumes 5, 9 and 7 are always very nearly the same.
- a starting point may be with the low pressure slot registering with ports 14 and 16 and displacer 4 in an uppermost position, and displacer 8 in a lowermost position so that volumes 7 and 11 are at low pressure and displacer 4 is in its highest position (FIG- URE l).
- the rotary valve moves bringing high pressure port 26 into register with port 14 thus increasing pressure in volume 3 and driving displacer 4 to its lowest position in the cylinder 2. Then the high pressure slot 26 is brought into register with port 16 thereby increasing the pressure in volume 11.
- displacer 8 moving upwards compressing gas in volumes 9 and 5.
- the low pressure slot comes into register with port 14 letting pressure down in volume 3 unbalancing the pressure on displacer 4 so that the displacer 4 moves to its topmost position displacing gas from volumes 5 and 9 through the heat exchanger 32 where heat of compression is removed and then through thermal regenerator 34 where gas is cooled by storing refrigeration in the matrix of the regenerator.
- valve V2 As shown in FIGURE 1 which supplies additional high pressure gas through conduit 19 to volume 5 and volume 7 when the gas from valve 1 is being displaced from volume 5 to volume 7 so that pressure will not decrease when gas is transferred to the colder region 7 or increase in reverse.
- Valve V2 has high and low pressure slots 27 and 29 which in proper register to port 31 gives this specified function. Details of the valves V1 and V2 may be of the type shown in US. Patent No. 3,119,237.
- the invention may be embodied in two-stage system as shown in FIGURE 2 wherein the same but primed numerals refer to parts similar to those in FIGURE 1 and further including the additional cylinder 2', displacer 4", and displacer 34'.
- the additional cylinder and displacer define three new volumes 3" connected with 3', 5" connected to 5' and 9', and '7" interconnected through additional regeneration 34" with volume 7 Displacer 4" moves in unison with displacer 4' so that volumes 3", 5" and 7" serve a similar function to 3', 5' and 7.
- the refrigeration achieved in volume 7" will be at a different lower temperature than that in 7'.
- a refrigeration apparatus comprising a first enclosure having a displacer movable therein to vary an upper volume, an intermediate volume and a lower volume, gas conduit means connecting the lower volume and the intermediate volume and said conduit means having a heat exchanger and a regenerator member located therein, a second enclosure mounted adjacent the first enclosure and a second displacer movable in the said second enclosure member to vary an upper volume and a lower volume, means for supplying a compressed gas, a motor driven rotary valve member rotatable to regulate flow of compressed gas from the supply means, said valve being formed with a high pressure gas passageway and a low pressure gas passageway, said valve being further formed with a port for communicating with the high pressure passageway in one position of rotation of the valve memher and a second port for communicating with the low pressure pasageway in another position of rotation of the valve member, a gas conduit connecting the said valve with the said lower volume of the second enclosure mem ber, an additional gas conduit connecting the valve with the upper volume of the said first enclosure and said upper volume of the said second enclosure
- a structure according to claim 3 in which a second valve member is employed and an additional enclosure member with upper, intermediate and lower volumes is connected thereto.
