Abstract

A seal housing with fluid regulating capability is provided for use with an outlet. The seal housing includes a seal element, a fitting and a valve. The seal element includes an angled flange that is fittable to the outlet and a seal element body from which the angled flange extends. The seal element body defines a bore extending between opposite open ends of the body and receptive of fluid from the outlet. The fitting is configured to tightly engage with the outlet and to urge the angled flange against the outlet with increasing pressure as fitting-outlet engagement proceeds. A valve is constrained within the bore and configured to regulate a flow of the fluid, which is received from the outlet, through the bore.

First claim

What is claimed is:

1 . A seal housing with fluid regulating capability for use with an outlet, the seal housing comprising:
a seal element comprising an angled flange that is fittable to the outlet and a seal element body from which the angled flange extends, the seal element body defining a bore extending between opposite open ends of the body and receptive of fluid from the outlet; a fitting configured to tightly engage with the outlet and to urge the angled flange against the outlet with increasing pressure as fitting-outlet engagement proceeds; and a valve constrained within the bore and configured to regulate a flow of the fluid, which is received from the outlet, through the bore.

2 . The seal housing according to claim 1 , wherein the angled flange is conical.

3 . The seal housing according to claim 1 , wherein the seal element body comprises:
an aft end which is insertible into the outlet; a forward end; and a central portion interposed between the aft and forward ends and from which the angled flange extends about the aft end.

4 . The seal housing according to claim 1 , wherein the fitting comprises internal threading which is engageable with external threading of the outlet.

5 . The seal housing according to claim 1 , wherein the fitting comprises an annular body which is freely rotatable about the seal element body and comprises a surface which is abuttable with the angled flange.

6 . The seal housing according to claim 1 , wherein the valve comprises a check valve.

7 . The seal housing according to claim 1 , wherein the valve comprises:
a valve body affixed to an interior facing surface of the seal element body and comprising a valve seat; and a piston which is anchored to the valve body and elastically biased toward the valve seat.

8 . The seal housing according to claim 7 , further comprising a spring by which the piston is anchored to the valve body and which is configured to elastically bias the piston toward the valve seat.

9 . A seal for a male outlet having a predefined fluid regulating capability, the seal comprising:
a seal body comprising:
an aft end including a first surface abuttable with the male outlet and a second surface opposite the first surface; and
a forward end defining a bore having a fluid regulating capability reduced as compared to the predefined fluid regulating capability of the male outlet;
a female fitting comprising:
an aft end configured for engagement with the male outlet; and
a forward end disposable about the seal body; and
an intermediate body interposable between the female fitting and the seal body and movable about the seal body with the female fitting, the intermediate body comprising a surface configured to abut with the second surface and to force the first surface against the male outlet as the aft end of the female fitting engages with the male outlet.

10 . The seal according to claim 9 , further comprising a check valve constrained within the bore.

11 . The seal according to claim 9 , wherein the male outlet comprises a conical end and the first and second surfaces are conical and the forward end of the seal body has a tubular shape.

12 . The seal according to claim 9 , wherein an interface between the aft and forward ends of the seal body comprises a radial shoulder curving toward the aft end of the seal body a rounded corner that turns toward the forward end of the seal body.

13 . The seal according to claim 9 , wherein the aft end of the female fitting comprises interior threading which is threadably engageable with exterior threading of the male outlet.

14 . The seal according to claim 9 , wherein the forward end of the female fitting is disposable about an entirety of the aft end and a portion of the forward end of the seal body.

15 . The seal according to claim 9 , wherein the intermediate body is freely rotatable and translatable about and along the seal body, respectively, and the surface of the intermediate body is conical.

16 . The seal according to claim 9 , wherein the forward end of the female fitting and an exterior surface of the intermediate body cooperatively define a wire insertion region.

17 . The seal according to claim 9 , wherein:
a forward-most end of the intermediate body comprises a flange, and a region defined radially between the flange and the forward end of the seal body is receptive of a tube.

18 . A method of providing a seal for a male outlet having a predefined fluid regulating capability, the method of providing the seal comprising:
forming a seal body such that the seal body comprises:
a seal feature including a first surface abuttable with the male outlet and a second surface opposite the first surface;
a tubular feature defining a bore having a fluid regulating capability reduced as compared to the predefined fluid regulating capability of the male outlet; and
a retention feature configured to trap the seal feature against the tubular feature;
forming a female fitting such that the female fitting comprises:
an aft end configured for engagement with the male outlet; and
a forward end disposable about the seal body; and
forming an intermediate body to be interposable between the female fitting and the seal body and movable about the seal body with the female fitting, the intermediate body comprising a surface configured to abut with the second surface and to force the first surface against the male outlet as the aft end of the female fitting engages with the male outlet.

19 . The method of providing the seal according to claim 18 , further comprising constraining a check valve in the bore.

20 . The method of providing the seal according to claim 18 , wherein the male outlet comprises a conical end and the first and second surfaces are conical.
