A fluid channeling device including a channeling body, an axial transfer channel, and a radial outlet channel. The channeling body includes first and second annular body sections spaced axially apart and a tubular body section extending between the first and second body sections. The axial transfer channel is defined axially through the channeling body, and is configured to fluidly couple a first compression assembly with a second compression assembly. The radial outlet channel is defined radially through the channeling body and is configured to fluidly couple the second compression assembly with an outlet.

1. A compressor comprising: a casing having an interior chamber, a central axis extending through the interior chamber, and an outlet; first and second compression assemblies disposed in the interior chamber, spaced axially apart along the central axis, wherein each of the first and second compression assemblies has an inlet, an outlet, and at least one compressor stage including an impeller; and a fluid channeling device including a channeling body disposable in the interior chamber, axial transfer channels configured to fluidly couple the outlet of the first compression assembly with the inlet of the second compression assembly, and radial outlet channels configured to fluidly couple the outlet of the outlet of the second compression assembly with the outlet of the casing; and a first flow passage defined in the casing, disposed between and configured to fluidly couple the outlet of the first compression assembly with the inlet of the second compression assembly, and including an annular section extending axially along the central axis of the casing; and a second flow passage defined in the casing, disposed between and configured to fluidly couple the outlet of the second compression assembly with the outlet of the casing, and including a radial section extending perpendicularly to and through the first flow passage such that the first and second flow passages commonly include an annular channel, wherein the channeling body is annular, disposable in the annular channel, and configured to prevent substantial fluid flow between the first and second flow passages. 2. The compressor of claim 1, further comprising first and second cylindrical members spaced axially apart to axially define the annular channel, wherein the channeling body is disposable between the first and second cylindrical members. 3. The compressor of claim 2, wherein: the first compression assembly includes a first outer sleeve member disposed around the first cylindrical member;the second compression assembly includes a second outer sleeve member disposed around the second cylindrical member; andthe channeling body includes first and second annular body sections spaced apart along the central axis and tubular body sections extending between the first and second annular body sections and spaced apart circumferentially, wherein the first annular body section is disposable at least partially in the first outer sleeve member and the second annular body section is disposable at least partially in the second outer sleeve member. 4. The compressor of claim 3, wherein the radial outlet channels are axially defined between the first and second annular body sections and radially defined between adjacent tubular body sections. 5. The compressor of claim 3, wherein: each one of the tubular body sections includes a central bore, a first open end and a second open end;the first annular body section includes first openings;the second annular body section includes second openings;the first open end of each one of the tubular body sections is disposed in one of the first openings and the second open end of each one of the tubular body sections is disposed in one of the second openings; andthe axial transfer channels extend from the outlet of the first compression assembly, through the first annular body section, through the first openings, through the tubular body sections, through the second openings, through the second annular body section, and to the inlet of the second compression assembly. 6. The compressor as recited in claim 2, wherein a central bore is defined through the channeling body, wherein the radial outlet channels extend from the central bore, radially through the channeling body, and to the outlet of the casing.
