Myinvention relo tcs to rotary rcii'ig erst ing machines of the type in. which suitable ninteriel, such as sulfur-dioxid in the form of e. sstureted or uporouimutelysaturated c.3901 or is confined in o lier neticelly seeled co;
iner, comprising e compressor condenser portion and, o refrigerator in such machines. the sulfnndii other .euibeble refrigemnt, is ected nieclniniceliv in the compressor or con densee portion contzttiner to cause it cite and lose potential energy in "the form 'o-f wbiclf is transmitted to and dissipated by of medium out-side that poi tion of the container; the material within the condenser po 'lzion being then conveyed to refrigerator portion where it vaporises and effects the refrigeration ofa me dium surrounding that portionbii the con miner bv absorbing beat therefrom. Besides the, sulfundioxid or similar refrigerant, the conte' i' also has a lubricant therein for lubricu the Working parts of the refrigerating machine. Such a. machine is described in the U. S. patent to Audifitren end Singriin lilo. 1.155.780, dated @ctoloer 5., 1915, end the ll. patent to J. J. Wood No. menses, dated December 1%, 1915.
such machines. it is impra cticnbio to get comnlete separation of the lubricant and 1iquid iefrigerent in. be condenserportion of tbe machine, with the result that tbs-liquid refrigerant pa sing; from the condenser "poo tion of the machine to refrigerator por tion carries with it some lubricant which must be returned to the condenser portion.
in order to accomplish this, the reirig'erntor portion of the niacliineis provided with u liquid and lubricant separator e rrenged to collect the lubmcnnt and refrigerant, sepastruction containing fewer'parts than those bereoofore used.
For a. full and complete understanding of the novel features of construction of my invention. reference may be had to the fol-- lowing description taken in connection with the accompanying drawing, in which ,Figure 1 is s. wctionol view through the refrigerator portion of the container of a refrigerating machine, showing the separator of my invention partly in cross section, and Fig. 2
"is a side view, part1 in cross section, of the separator removed 0111 the container.
Referring to the drawing, 1 is the refrigerator portion of the hermeticallysealed container of the refrigerating machine which is connected by a hollow shaft 2 to the condenser ortion of the machine.
Projecting t rough the hollow shaft. 2 into the portion 1 of the container; is {L bollow stationary tube 3 which serves toconvey the refrigerating liquid from the condenser to the refrigerator portion. On this stationery tube 3 is mounted my separator which comprises a central member 4, a U- shaped member, consisting of two U-shoped tubes 9 and 19.. fastened to the member 4 and having one end communicating with the interior thereof, and a collector 14 mountedon the other end of the U-shapedmember extending into. proximity with the periphery of the container for conveying liquid from adjacent the periphery of the con tainer to said lei-shaped member. The cen tral member i is shown as a rectangular box provided at one side with a clamping portion 5 by which it is attached to the stationary hollow tube. 3, and at the opposite side with a projecting hub 6 by which it isloosely journaled ontbe shaft 2.
The bottom oftl e central member 4 is solid and its two sides are shaped to receive the two ends respectively of the U-shiped tube 9 which is riveted or otherwise permenently attached thereto as best shown in Fig. 2. Between one of these sides of the central member 4 and the adjacent leg of the U- shaped tube 9 is provided a communicating passage 10. In the other leg of U-shaped,
,lWithin the U-sbeped tube 9 is located the second U-shcped tube 1.2, of relatively small the tube 12 is first placedin the is loceied in the leg who 9 vided with ville V8Tfl0W;p1})8 l1.
placed in the mm diameter. fine end. of the ll slmped tube 12 extends Well who've the end of the outer Ueheped tube 9, and the other end 16 of the tube 12 terminates below the point where the tube 9 with the centrel member The long leg oi inner tube 125 which is pro- "in order to facilitate the assembly of the ll-shsped member consisting of the tubes 9 and 12, the outer tube 9 is split at In assembling, bent portion of the tube 9. After the tube 12 is put in place in this portion. of tube 9, the straight section of she legmi tnheQ above the split 13 is placed in position and welded or otherwise attached to the not porlion of tube 9 at the joint 13.
On the end of the ei-shaped who 12 which extends beyond the tube, 9 is iinsiened a projectingfin-shaped liquid collector 1% which extends into close proximity to the perlpl1- cry of the oontelner. This liquid colleci/or M is shown as loeing constructed in accordance with my lleiene l lo. 1,281,821, defied ()c zoher 15, 19113.
The top of the central member l is pre vided with an opening '2' and a surrounding lug 17. On this lug 17 is fitiecl one end of a bent tube It is shown as being-mounted in a, plane at right angles to t-he'membe: 3.
The operation oi my seggeretoi' is as fol lows:-'ihe collector Ll clips'lnto the film of lubricant and refrigerants and carries the proper enionni down into the cube 1:2 of the U-sheped member. The mixture of the lubricant liquid refrigerant carried into the mm 12 flows out of the end 16 thereof and the refrigerant, being the heavier, drops "'3 the bottom of the outer ll-shaped inhe As it rises shove the bend in this tube, it causes the lighter lubricenl;
to rise only in. the right-hand leg of who 9 i (Fig. 53); the refrigerant settling in the curve and ii in loot-h legs of who 9. When. lubricant rises in the right-hand leg of tube (1 to flows throu the passiage 10 into ohe cen trel niemhe, l {min which it is sucked back into the compressor portion of the machine through. she hollow she'll Z. The liquid refrigerant es in the left-hand leg of tube 9 and lions out th ough the oerfiow pipe 11 and is disc-horged ggoinsi the Well of ooziminezr 1 Well up tmvm'd the shaft 2. The height at which the overflow pipe 11 is 9 determined by ilhe (li'llerence in specific gravity of the lubri cunt and liquid refrigerant.- This heighi; is made such that {L sniiirienl; amount ofliquicl refrigerantiesrapoed in ithe U-shepedmbe 9 lo raise {he of ahe lubricant to such a height list it will flow into lahe opening 10, Any oddiiional liquid refrigereni,
ffne level of the shaft, it i trapped. in the lfi-shepecl tube 9 will flow out of the overfio v pipe 11.
The evaporated refrigerant is sucked throughishe bent tube 8 into the central gin amber 1 and drawn through the hollow is in line with the splash from the oil sepzii retor, resmleing in a moist gas being sucked back into the compressor cylinders. In my improved separator, however, the free end oi the tube 8 is so located that this is prevented; and any moisture that may be drawn into the tube is deposited on the Wall of the free leg of this tube 8 and drops back into the i'efrigerator chamber, so the vapor which enters the shaft is comparatively dry.
ii desire it to be understood that nw invention is not limited to the particular Iorm or arrangement of parts shown and described herein, and I aim in the appended claims to cover all modifications which do not depart from the spitcil; and. scope of my invention.
What I claim as new and desire to secure by Letters Patent ofthe United States, is
