Abstract

A cross-over fluid coupling includes a first coupling end and a second coupling end. A plurality of first conduits have inner ends disposed toward the first coupling end and outer ends spaced apart from the inner end toward the second coupling end and being outboard of the inner end. A plurality of second conduits have outer ends that are disposed toward the first coupling end and positioned laterally outboard of the inner end of at least one of the first conduits, and inner ends that are spaced apart from the outer end toward the second coupling end in the axial direction and is laterally inboard of the outer end of the at least one of the first conduits.

Dependent claims

A cross-over fluid coupling comprising:

a first coupling end;
a second coupling end spaced apart from the first coupling end in an axial direction;
a plurality of first conduits extending between the first and second coupling ends and configured to allow fluid to flow through the cross-over fluid coupling, each first conduit having an inner end disposed toward the first coupling end and an outer end spaced apart from the inner end toward the second coupling end in the axial direction and being outboard of the inner end in a lateral direction that is orthogonal the axial direction;
and
a plurality of second conduits extending between the first coupling end and the second coupling end and configured to allow fluid to flow through the cross-over fluid coupling, each second conduit having an outer end that is disposed toward the first coupling end and positioned laterally outboard of the inner end of at least one of the first conduits, and an inner end that is spaced apart from the outer end thereof toward the second coupling end in the axial direction and is laterally inboard of the outer end of the at least one of the first conduits.

A cross-over fluid coupling for connecting a first set of pipes, having a first inner pipe and a first outer pipe at least partially surrounding the first inner pipe, to a second set of pipes, having a second inner pipe and a second outer pipe at least partially surrounding the second inner pipe, the coupling comprising:

a first coupling end connectable to the first set of pipes;
a second coupling end connectable to the second set of pipes and spaced apart from the first coupling end in an axial direction;
a plurality of first conduits extending between the first and second coupling ends and configured to allow fluid to flow between the first set of pipes and the second set of pipes, each first conduit having a first end fluidly connectable to the first outer pipe and a second end that is spaced apart from the first end toward the second coupling end in the axial direction and is fluidly connectable to the second inner pipe to fluidly connect the first outer pipe to the second inner pipe;
and
a plurality of second conduits extending between the first coupling end and the second coupling end and configured to allow fluid to flow between the first set of pipes and the second set of pipes, each second conduit having a first end that is connectable to the first inner pipe and a second end that is spaced apart from the first end toward the second coupling end in the axial direction and is connectable to the second outer pipe to fluidly connect the first inner pipe to the second outer pipe.
