Abstract

A fluid connector comprising a base having a first through-hole concentrically positioned therein, the base comprising a first inner surface and a first outer surface, the base comprising at least one annular groove extending radially outwardly from the first inner surface, at least one ring-shaped seal, each seal located within the at least one annular groove, a washer positioned within the first through-hole, the washer having an inwardly facing partially spherical surface, and, a body having a second through-hole positioned therein, the body comprising a second inner surface and a second outer surface, wherein the second outer surface is partially spherical in shape, wherein the second outer surface of the body engages the at least one seal and the inwardly facing partially spherical surface of the washer, wherein the body is arranged to swivel within the second through-hole, and to pass fluid through the second through-hole.

First claim

What is claimed is:

1. A fluid connector, comprising:
a base comprising a first through-hole concentrically positioned therein, said base comprising a first inner surface and a first outer surface, said base comprising a first annular groove and a second annular groove extending radially outward from said first inner surface;
a first annular seal, said first annular seal located within said first annular groove;
a second annular seal, said second annular seal located within said second annular groove;
a washer positioned within said first through-hole, said washer having an inwardly facing partially spherical surface and an angled surface connected to the inwardly facing partially spherical surface, wherein said angled surface is arranged at least partially within the second annular groove, wherein the angled surface comprises a first section coplanar with an axis perpendicular to a centerline of the first through-hole and a second section arranged at an angle relative to the axis in a first axial direction toward the second annular seal, wherein the angle is less than 90 degrees, wherein the first annular seal is arranged on a first axial side of the second annular seal and the washer is arranged on a second axial side, opposite the first axial side, of the second annular seal; and,
a body having a second through-hole positioned therein, said body comprising a second inner surface and a second outer surface, wherein said second outer surface is partially spherical in shape, comprising an apex, wherein said second outer surface of said body engages said first annular seal, said second annular seal, and said inwardly facing partially spherical surface of said washer,
wherein said body is arranged to swivel within said first through-hole of said base, and to pass fluid through said second through-hole of said body.

2. The fluid connector as recited in claim 1 , wherein said first annular seal is a rubber O-ring.

3. The fluid connector as recited in claim 1 , wherein said second annular seal is a rubber O-ring.

4. The fluid connector as recited in claim 1 , wherein said fluid connector further comprises a retainer clip secured to said body and arranged within said second through-hole.

5. The fluid connector as recited in claim 1 , wherein said body is arranged to swivel in a range of approximately 0-25 degrees with respect to the centerline of said first through-hole.

6. The fluid connector as recited in claim 1 , wherein said first outer surface further comprises screw threads.

7. The fluid connector as recited in claim 1 , wherein a protrusion axially arranged between the first and second annular grooves aligns with said apex of said second outer surface of said body when said body is swiveled 0 degrees with respect to the centerline of said first through-hole.

8. The fluid connector as recited in claim 1 , wherein said apex of said second outer surface of said body is arranged between said first annular seal and said second annular seal.

9. A fluid connector, comprising:
a base comprising a first through-hole concentrically positioned therein, said base comprising a first inner surface and a first outer surface, said base comprising a first annular groove and a second annular groove extending radially outward from said first inner surface;
a first annular seal, said first annular seal located within said first annular groove;
a second annular seal, said second annular seal located within said second annular groove;
a washer positioned within said first through-hole and arranged completely within said base, said washer having an inwardly facing partially spherical surface and an angled surface, wherein said angled surface is arranged at least partially within said second annular groove, wherein the angled surface comprises a first section coplanar with an axis perpendicular to a centerline of the first through-hole and a second section arranged at an angle relative to the axis in a first axial direction toward the second annular seal, wherein the angle is less than 90 degrees, wherein the first annular seal is arranged on a first axial side of the second annular seal and the washer is arranged on a second axial side, opposite the first axial side, of the second annular seal;
a body having a second through-hole positioned therein, said body comprising a second inner surface and a second outer surface, wherein said second outer surface is partially spherical in shape, comprising an apex, wherein said second outer surface of said body engages said first annular seal, said second annular seal, and said inwardly facing partially spherical surface of said washer,
wherein said body is arranged to swivel within said first through-hole of said base, and to pass fluid through said second through-hole of said body, said first annular seal operatively arranged on a first side of said apex, and said second annular seal operatively arranged on a second side of said apex, said second side opposite said first side; and,
a retainer clip fixedly secured to said body, said retainer clip positioned within said second through-hole.

10. The fluid connector as recited in claim 9 , wherein said first annular seal is a rubber O-ring.

11. The fluid connector as recited in claim 9 , wherein said second annular seal is a rubber O-ring.

12. The fluid connector as recited in claim 9 , wherein said retainer clip secures a connector tube to said fluid connector.

13. The fluid connector as recited in claim 9 , wherein a protrusion axially arranged between the first and second annular grooves aligns with said apex of said second outer surface of said body when said body is swiveled 0 degrees with respect to a centerline of said first through-hole.

14. The fluid connector as recited in claim 9 , wherein said apex of said second outer surface of said body is arranged between said first annular seal and said second annular seal as said body is swiveled at the maximum amount of degrees with respect to the centerline of said first through-hole of said base.

15. A fluid connector, comprising:
a base comprising a first through-hole concentrically positioned therein, said base comprising a first inner surface and a first outer surface, said base comprising a first annular groove and a second annular groove extending radially outward from said first inner surface;
a protrusion operatively arranged between said first annular groove and said second annular groove;
a first annular seal, said first annular seal located within said first annular groove;
a second annular seal, said second annular seal located within said second annular groove;
a washer secured within said first through-hole, said washer having an inwardly facing partially spherical surface and an angled surface, wherein said angled surface is arranged at least partially in said second annular groove, wherein the angled surface comprises a first section coplanar with an axis perpendicular to a centerline of the first through-hole and a second section arranged at an angle relative to the axis in a first axial direction toward the second annular seal, wherein the first annular seal is arranged on a first axial side of the second annular seal and the washer is completely arranged on a second axial side, opposite the first axial side, of the second annular seal;
a body having a second through-hole positioned therein, said body comprising a second inner surface and a second outer surface, wherein said second outer surface is partially spherical in shape, wherein said second outer surface of said body engages said first annular seal, said second annular seal, and said inwardly facing partially spher
