Claims
- 1. An improved gas compressor, comprising a gear housing; a driving gear and at least two driven gears enclosed within said housing; said driven gears being in engagement with said driving gear for rotation therewith on parallel, driven axes; said housing having parallel walls; a power input shaft, in penetration of one of said walls, drivingly coupled to said driving gear; at least two impellers for compressing gas, each impeller coupled to one of said driven gears externally of said housing; and means for admitting and discharging gas to and from said impellers; wherein the improvement comprises:
- at least two, annular, spaced-apart flanges projecting externally from the other of said parallel walls;
- said flanges each being concentric with, and circumscribing one of said impellers; and wherein
- said gas admitting and discharging means comprises a first, domed closure assembly having means coupling said first closure assembly to one of said annular flanges, and a second, domed closure assembly having means coupling said second closure assembly to another of said annular flanges;
- each of said closure assemblies comprising a first conduit for conducting gas therethrough to such impeller, of said at least two impellers, which is associated therewith, and a generally cup-shaped, closure head;
- said first conduit being in penetration of said closure head, having a terminal opening at one end thereof inside of said closure head, and a terminal opening at the other end thereof outside of said closure head, defining an annular chamber, inside of said closure head, concentric with said associated impeller's driven axis; further including
- a second conduit, coupled to and projecting from each of said closure heads, opening through said closure head and onto said annular chamber; and wherein
- said coupling means of each of said closure assemblies comprises an annular, terminal flange, concentric with said first conduit, which is replaceably secured, externally of said compressor, to one of said spaced-apart, externally-projecting flanges of said other wall, to accommodate removal and installation of each of said closure assemblies independently of others thereof and without any further dismantling or assembly of said compressor.
- 2. An improved gas compressor, according to claim 1, wherein:
- said second conduit projects from said closure head transverse to said axes.
- 3. An improved gas compressor, according to claim 1, further including:
- means replaceably coupled to said other wall at least one of said first and second domed closure assemblies for heat exchanging coolant with gas discharged from said associated impeller.
- 4. An improved gas compressor, according to claim 1, further including:
- means coupled to said second conduit of one of said closure heads and to said first conduit of another of said closure heads, external of said compressor, for conducting gas therebetween.
- 5. An improved gas compressor, according to claim 3, wherein:
- said heat exchanging means includes a pipe in penetration thereof which communicates with said first conduit.
- 6. An improved gas compressor, according to claim 3, wherein:
- said heat exchanging means comprises a subassembly of annular cross-section which is concentric with said associated impeller and said first conduit.
- 7. An improved gas compressor, according to claim 3, wherein:
- said heat exchanging means includes demister means for entraining moisture and removing the same from gas.
- 8. An improved gas compressor, according to claim 3, further including:
- means coupled to said second conduit of said at least one domed closure assembly and to said first conduit of another of said domed closure assemblies, external of said compressor, for conducting gas therebetween.
- 9. For use with a gas compressor or the like, an improved heat exchanging assembly, comprising a housing; means defining an annular heat exchanger confined within said housing; said heat exchanger having a central, through-traversing pipe for admitting gas therethrough into said housing; and means for discharging gas from said housing through said heat exchanger; wherein the improvement comprises:
- a generally cup-shaped closure head at one end of said housing;
- said one end of said housing and said closure head having mating, interfacing flanges;
- said interfacing flanges being separably fastened together;
- said closure head having a conduit in penetration thereof;
- said conduit opening at one end thereof externally of said closure head, and opening internally of said closure head in communication with said through-traversing pipe;
- said housing being open-ended at the end thereof opposite said one end;
- said opposite end of said housing having an external coupling flange formed thereon; and
- said one end of said conduit also having an external coupling flange formed thereon; wherein
- said conduit cooperates with said closure head to define an annular chamber within said closure head; and further including a gas discharge pipe opening at one end thereof through said closure head and onto said annular chamber therewithin, and opening at the other end thereof externally of said closure head; and
- said other end of said gas discharge pipe has an external coupling flange formed thereon.
- 10. An improved heat exchanging assembly, according to claim 9, further including:
- demister means, confined within said annular chamber in said closure head, for entraining and removing moisture from gas.
