Application filed July 27, 1923. Serial No. 654,282.
To all whom it may concern:
machines comprising a plurality of chambers for successlvely compressing elastic fluids.
As is known to those skilled in the art, the temperature of the elastic fluid is raised by two stages and to include cooling means intermediate-the stages. The object of-the improvements is to, provide a system in which separate compressors are dispensed with, and with this object in view I provide a conduit for successively connecting a pressure chamber of higher pressure with a pres.- sure chamber of lower pressure, and I include coolingmeans in the conduit connecting the said chambers; Thereby a part of the fluid which has been compressed and heated is successivelytaken from the chami piston 4 mounte the line 3-3 of Fig. 2.
bars of higher pressure, cooled, and thereafter passed into the chambers of lower ressure, where it cools the fluid which has een partly compressed and heated, so that the final tem rature of the fluid does not exceed the egree allowed for practical reasons.
For the purpose of explaining the inven tion an example embodying the same has been shown in the accompanying drawings in which the same reference characters have been used in all the views to indicate corresponding parts. In said drawings,
, Flg. 1, is a vertical cross-section of a ro- 2, I ig. 2, is; a longitudinal section taken the line 2 2 of Fig. 1, and
As appears from Fig. 2, the passages 7 and 8 are preferably disposed respectively at opposite ends of the casing,l, and they are preferably arranged so that they communicate temporarily with .thesame chamber The operation of the system is as follows:
The piston 4 rotates in the direction of tho arrow 13. By centrifugal action or by other means the blades 5 are held in contact with a the inner wall of the casing 1, so that the space between the casing 1 and the piston 4' Y is divided into separate chambers," which chambersmove in the upper part of Fig. 1
in the direction from the left to the right P and in the lower part from the right to the left. While moving through the section of the machine located at the left of the verti cal median planeof Fig. 1 the capacity of city of the chambers is reduced, so that the fluid is gradually compressed. If now the" blades 5 are in the positions shown'in Fig. 1 in broken lines, a chamber of higher pressure communicates with the outletpassage 'T and a chamber of lower pressure with the. inlet 8. Therefore a part ofthe fluid confined within the chamber 7 flows through the pipes 14, the cooling coil 9 and the inlet passage 8' into the chamber of lower ressure, the volume of the fluid flowing rom one chamber to the other being regulated by valve 11. After the fluidcoming from the chamber of higher pressure. has been cooled within the cooling system 9, 10, it ,cools the fluid combined withintheehamber of lower pressure. The'fluid confined with-- in, the chamber .of lower pressure is in part mixed with the cooled gas coming from the chamber of higher pressure, and apart is forced into the part of the said chamber which is opposite to the inlet passage 8.}. Therefore the fluid is made to flow ,through. the chamber in the direction from the inlet passage 8 to the discharge passage 7. Pref-1 erablysaid passages are, disposed so that they communicate temporarily with parts of their cross-sectional area or with their whole area with the same fluid chamber, as has been chamber which before communicated with the inlet passage 8 is brought into communication with the discharge passage 7, a part of the fluid escapes by reason of the increased pressure, and more particularly the part which is next to the discharge passage and which is at higher temperature than the part found at the side of the inlet passage. The movement of the fluid is started by some kind of blowing action which takes place when both passages 7 and 8 open into the same chamber, and it is supported by the fact that within the pipes 14 and the coil 9 the fluid is in' continuous motion in a direction towards the inlet passage 8. In some cases I provide additional means for circulating the fluid, such as the blower or fan 12 included in the pipes 14:, which blower is provided with driving means of its own.
or which is driven by the compressed fluid within the cooling coil 9. After the chamber has passed beyond the outlet passage7, the
compression of the cooled fluid is completed, the final temperature being reduced as compared to a system in which no cooling means are provided. By. cooling the fluid .the power required for driving the compressor is reduced.
While in describing the invention reference has been made to a particular example embodying the same I wish it to be understood that my invention is not limited to the construction shown in the drawings,
. and that various changes may be made in in ca acit and increasin ressure of a" conduit communicating with successive chambers of difi'erent pressure and includ ing cooling means. L 2.

- conduit communicating with chambers of different pressure and including, cooling means. said conduit having its ends arranged for opening into each of the charms 1 bers at opposite ends thereof.
3. In a system of the class'described the combination, ,with a rotary machine comprising fluid chambers of gradually decreas- 7 ing capacity and increasing pressure, ofa
conduit communicating with chambers of 'diflerent pressure and including cooling means, the ends of said conduit being so dlSPOSGd clrcumferentially of the machine that they open temporarily into the same chamber. n

In a system of the class described the combination, with a rotary machine comprising fluid chambers of gradually decreasing capacity and increasing pressure, of a conduit communicating with chambers of different pressure and including cooling means, said conduit opening into the chambers at opposite ends thereof and its ends being spaced circumferentially of the machine so that they open temporarily'into the same chamber. v
