Abstract

An example fitting includes: a fitting body having counterbore, where the counterbore defines an annular shoulder within tire fitting body: a spring having a first end interfacing with the annular shoulder of the counterbore; and a seal carrier having: (i) a first end face interfacing with a second end of the spring, (ii) a second end face configured to interface with an internal surface of a port, such that the spring is configured to apply a biasing force on the seal carrier toward the internal surface of the port, (iii) a first annular groove on an exterior peripheral surface of the seal carrier, where the first annular groove is configured to have a radial seal disposed therein, and (iv) a second annular groove in the second end face, where the second annular groove is configured to have a face seal disposed therein.

First claim

What is claimed is:

1. A fitting comprising:
a fitting body having counterbore formed therein, wherein the counterbore defines an annular shoulder within the fitting body;
a spring having a first end interfacing with the annular shoulder of the counterbore; and
a seal carrier having: (i) a first end face interfacing with a second end of the spring, (ii) a second end face configured to interface with an internal surface of a port, such that the spring is configured to apply a biasing force on the seal carrier toward the internal surface of the port, (iii) a first annular groove on an exterior peripheral surface of the seal carrier, wherein the first annular groove is configured to have a radial seal disposed therein, and (iv) a second annular groove in the second end face, wherein the second annular groove is configured to have a face seal disposed therein, wherein the spring and the seal carrier are made as a one-piece seal carrier and spring having a spring portion operating as the spring and a seal carrier portion operating as the seal carrier.

2. The fitting of claim 1 , wherein the fitting has a respective first end configured to be coupled to a fluid line and a respective second end configured to be coupled to the port, wherein the fitting body defines therein a fluid passage that fluidly couples the first end to the second end of the fitting.

3. The fitting of claim 1 , wherein the fitting body includes external threads disposed on a respective exterior peripheral surface of the fitting body and configured to engage with internal threads of the port to couple the fitting body to the port.

4. The fitting of claim 1 , wherein the fitting body further includes an annular groove disposed on a respective exterior peripheral surface of the fitting body, wherein the annular groove is configured to receive an ingression seal to be disposed between the fitting body and the port so as to preclude leakage from an external environment of the fitting body to within the fitting body.

5. An assembly comprising:
a port integrated into a manifold or a fluid line, the port comprising a port body, wherein the port body has first counterbore formed therein, wherein the first counterbore defines a first annular shoulder within the port body, and wherein the port body includes internal threads disposed on an interior peripheral surface of the port body; and
a fitting comprising:
a fitting body having a second counterbore formed therein, wherein the second counterbore defines a second annular shoulder within the fitting body, wherein the fitting body includes external threads disposed on an exterior peripheral surface of the fitting body configured to threadedly engage the internal threads of the port body to couple the fitting to the port;
a spring having a first end interfacing with the second annular shoulder of the second counterbore; and
a seal carrier having: (i) a first end face interfacing with a second end of the spring, (ii) a second end face configured to interface with the first annular shoulder of the port body, such that the spring is configured to apply a biasing force on the seal carrier toward the first annular shoulder of the port body, (iii) a first annular groove on a respective exterior peripheral surface of the seal carrier, wherein the first annular groove includes a radial seal disposed therein between the seal carrier and a respective interior peripheral surface of the fitting body, and (iv) a second annular groove in the second end face, wherein the second annular groove includes a face seal disposed therein between the second end face of the seal carrier and the first annular shoulder of the port body, such that the face seal contacts, and seals against, the first annular shoulder of the port body, wherein the port couples the fitting to the manifold or the fluid line.

6. The assembly of claim 5 , wherein the fitting has a respective first end configured to be coupled to a fluid line and a respective second end coupled to the port, wherein the fitting body defines therein a fluid passage that fluidly couples the first end to the second end of the fitting.

7. The assembly of claim 5 , wherein the fitting body further includes an annular groove disposed on the exterior peripheral surface of the fitting body, wherein the annular groove includes an ingression seal disposed between the fitting body and the port so as to preclude leakage from an external environment of the fitting body to within the fitting body.

8. The assembly of claim 5 , wherein the spring and the seal carrier are made as a machined one-piece seal carrier and spring having a spring portion operating as the spring and a seal carrier portion operating as the seal carrier.

9. The assembly of claim 5 , wherein the spring is configured as a friction spring comprising one or more inner rings mating with one or more outer rings, such that each outer ring has an interior annular tapered face interfacing with an exterior annular tapered face of an inner ring.

10. The assembly of claim 9 , wherein each inner ring has an outward protrusion at an edge of the inner ring configured to interact with an inward protrusion at a respective edge of a mating outer ring.

11. The assembly of claim 9 , wherein at least one of the outer rings is configured as a split ring.

12. The assembly of claim 5 , wherein the fitting body includes a longitudinal groove disposed on the exterior peripheral surface of the fitting body, wherein the port body includes a hole configured to receive a locking screw, such that a head of the locking screw is disposed partially within the longitudinal groove of the fitting body to preclude rotation of the fitting body relative to the port body when the fitting is coupled to the port.

13. A fluid system comprising:
a manifold having a port comprising a first counterbore formed therein, wherein the first counterbore defines a first annular shoulder within the port, and wherein the port includes internal threads disposed on an interior peripheral surface of the port;
a fluid line; and
a fitting having a first end coupled to the fluid line and a second end coupled to the port, such that fitting fluidly couples the fluid line to the manifold, wherein the fitting comprises:
a fitting body having a second counterbore formed therein, wherein the second counterbore defines a second annular shoulder within the fitting body, wherein the fitting body includes external threads disposed on an exterior peripheral surface of the fitting body configured to threadedly engage the internal threads of the port to couple the fitting to the port;
a spring having a first end interfacing with the second annular shoulder of the second counterbore; and
a seal carrier having: (i) a first end face interfacing with a second end of the spring, (ii) a second end face configured to interface with the first annular shoulder of the port, such that the spring is configured to apply a biasing force on the seal carrier toward the first annular shoulder of the port, (iii) a first annular groove on a respective exterior peripheral surface of the seal carrier, wherein the first annular groove includes a radial seal disposed therein between the seal carrier and a respective interior peripheral surface of the fitting body, and (iv) a second annular groove in the second end face, wherein the second annular groove includes a face seal disposed therein between the second end face of the seal carrier and the first annular shoulder of the port.

14. The fluid system of claim 13 , wherein the fitting body further includes an annular groove disposed on the exterior peripheral surface of the fitting body, wher
