Abstract

A flexible hose assembly is disclosed. The flexible hose assembly has a first coupling member with a first anti-rotational element on a first end and a crimping element on a second end, the crimping element being configured to receive a first flexible hose. The flexible hose assembly also has a second coupling member with a second anti-rotational element on a first end, the second anti-rotational element being configured to mate with the first anti-rotational element. The flexible hose assembly also has a clamping ring configured to retain the first ends of the first and the second coupling members together.

First claim

What is claimed is:

1. A fluid coupling, comprising:
a coupling end for mechanically and fluidly joining the fluid coupling to another fluid coupling, the coupling end having a face;
a fluid orifice disposed on the face, the fluid orifice defining a central axis;
a plurality of ridges disposed around the fluid orifice in the face of the coupling end, wherein each of the plurality of ridges has a longitudinal dimension, the longitudinal dimension of each of the plurality of ridges extending radially outward from the central axis, wherein peaks of the plurality of ridges are flush with the face; and
a sealing member at least partially inset in the face of the coupling end around the fluid orifice.

2. The fluid coupling of claim 1 , wherein each ridge of the plurality of ridges has a substantially triangular cross-sectional shape when the cross-section is taken circumferentially about the central axis.

3. The fluid coupling of claim 1 , wherein the plurality of ridges allow for multiple angular orientations of the fluid coupling relative to the another fluid coupling while inhibiting relative rotation between the fluid coupling and the another fluid coupling when the fluid coupling engages with the another fluid coupling.

4. The fluid coupling of claim 1 , wherein the sealing member is located radially inward of the plurality of ridges.

5. The fluid coupling of claim 1 , further including external threads for engagement with internal threads of the another fluid coupling.

6. A fluid coupling assembly, comprising:
a first coupling member including:
a first coupling end including a first face;
a body;
a neck located between the body and the first coupling end, the neck having a diameter that is smaller than a diameter of the first coupling end and the body;
a first fluid orifice disposed on the first face, the fluid orifice defining a central axis, the first fluid orifice leading to a first fluid passageway that passes through the first coupling end, neck, and body of the first coupling member;
a first plurality of ridges disposed on the first face of the first coupling end, wherein each of the first plurality of ridges has a longitudinal dimension, the longitudinal dimension of each of the first plurality of ridges extending radially outward from the central axis;
a sealing surface disposed on the first face of the first coupling end around the first fluid orifice; and
a clamping ring including internal threads connected to the first coupling member; and

a second coupling member including:
a second coupling end including a second face;
a second fluid orifice disposed on the second face;
a second plurality of ridges disposed on the second face of the second coupling end, wherein the second plurality of ridges are configured to mate with the first plurality of ridges;
a sealing member at least partially inset in the second face of the coupling end around the second fluid orifice such that a surface of the second face is located on a radially interior side of a radially inner edge of the sealing member and another surface of the second face is located on a radially exterior side of a radially outer edge of the sealing member; and
external threads configured to engage the internal threads to couple the first and second coupling members together, wherein the sealing member is compressed against the sealing surface upon coupling of the first and second coupling members.

7. The fluid coupling assembly of claim 6 , wherein each ridge of the first plurality of ridges has a substantially triangular cross-sectional shape when the cross-section is taken circumferentially about the central axis.

8. The fluid coupling assembly of claim 6 , wherein when traveling about the central axis in a circumferential direction at a constant radius, the first plurality of ridges define peaks and valleys, wherein the first and second plurality of ridges allow for multiple angular orientations of the first coupling member relative to the second coupling member while inhibiting relative rotation between the first coupling member and the second coupling member when the first plurality of ridges engage with the second plurality of ridges.

9. The fluid coupling assembly of claim 8 , wherein the sealing member is located inward of the second plurality of ridges.

10. The fluid coupling assembly of claim 6 , wherein the clamping ring is slidably disposed on the neck portion of the first coupling member.

11. The fluid coupling assembly of claim 6 , wherein at least one of the first coupling member or the second coupling member includes a crimping portion.

12. The fluid coupling assembly of claim 11 , wherein the crimping portion is connected to a flexible hose.

13. The fluid coupling assembly of claim 6 , wherein peaks of the second plurality of ridges are flush with the second face.

14. A fluid coupling assembly, comprising:
a first coupling member including:
a first coupling end including a first face;
a body;
a neck located between the body and the first coupling end, the neck having a diameter that is smaller than a diameter of the first coupling end and the body;
a first fluid orifice disposed on the first face, the first fluid orifice leading to a first fluid passageway that passes through the first coupling end, neck, and body of the first coupling member;
a first plurality of ridges disposed on the first face of the first coupling end;
a clamping ring including internal threads connected to the first coupling member, wherein a radially inner surface of the clamping ring is slidably disposed along an outer surface of the neck; and

a second coupling member including:
a second coupling end including a second face;
a second fluid orifice disposed on the second face defining a central axis;
a second plurality of ridges disposed on the second face of the second coupling end, wherein each of the second plurality of ridges has a longitudinal dimension, the longitudinal dimension of each of the second plurality of ridges extending radially outward from the central axis, wherein peaks of the second plurality of ridges are flush with the second face, the first plurality of ridges being configured to mate with the second plurality of ridges to inhibit rotation of the first coupling member relative the second coupling member when the first plurality of ridges engage with the second plurality of ridges; and
a threaded portion having external threads configured to engage the internal threads to couple the first and second coupling members together.

15. The fluid coupling assembly of claim 14 , wherein at least one of the first coupling member or the second coupling member includes a crimping portion.

16. The fluid coupling assembly of claim 14 , wherein the first coupling end, the body, and the neck of the first coupling member are integral components.
