Abstract

A fluid quick connector with a shut off valve interface is mountable on a first endform, such as a building plumbing stub out. The quick connector carries a retainer at an opposite end for releasable latching of a second fluid operative element to the stub out. An internally movable shut off valve is carried in the quick connector housing and is normally biased to a fluid blocking position. Insertion of a second endform through the second end of the quick connector housing overcomes the biasing force on the valve and moves the valve to an open fluid flow position allowing fluid flow between the stub out and the second endform.

Claims

1. A fluid quick connector for mounting on a first endform comprising:

a housing having a bore extending between first and second ends;

a first retainer carried at the first end of the housing adapted for releasably latching the housing to the first endform;

a valve movably mounted in the bore for movement in a first direction to close the bore in housing to fluid flow, and oppositely in a second direction to open flow through the bore in the housing; and

a second retainer carried by the housing adapted for releasably latching a second endform in the housing.

2. The quick connector of claim 1 further comprises:

means for biasing the valve in a first direction in the housing into sealing engagement with the housing.

3. The quick connector of claim 1 wherein the first retainer comprises:

means for one way slide on engagement with the first endform.

4. The quick connector of claim 3 wherein the first retainer comprises:

an annular member having a through bore mountable over the first endform and a plurality of circumferentially arranged angled spring fingers engageable with the first endform.

5. The quick connector of claim 1 further comprising:

a carrier mountable in the first end of the housing, the sleeve carrying the first retainer.

6. The quick connector of claim 5 further comprising:

seal means mounted between the sleeve and the first housing for sealingly coupling the sleeve to the housing.

7. The quick connector of claim 1 where the second retainer comprises:

a bore adjacent the second end of the housing extending transversely to the bore extending between the first and second ends of the housing, the second retainer movable through the transverse bore and engageable with the second endform.

8. The quick connector of claim 7 further comprising:

a radially inwardly extending recess formed in the second endform; and

a radially outward extending projection carried by the retainer and engageable with the recess in the endform to releasably latch the retainer to the endform.

9. The quick connector of claim 1 further comprising:

at least one recess formed in the housing opening to the bore extending between the first and second ends of a housing; and

the valve operable to close off fluid communication between the recess in the housing and a remaining portion of the bore extending to the second end of the housing when in the closed position in the housing.

10. The quick connector of claim 9 wherein the valve further comprises:

at least one aperture formed in the valve and disposed in fluid flow communication with at least one recess in the housing when the valve is in first position to open fluid flow between the first and second ends of the housing.

11. The quick connector of claim 10 further comprising:

at least one recess in the housing that includes a plurality of circumferentially spaced recesses; and

at least one aperture in the valve comprises a plurality of circumferentially spaced apertures.

12. The quick connector of claim 9 further comprising:

a sleeve mounted in the bore in the housing, the at least one recess carried in the sleeve.

13. A fluid quick connector for mounting on a first endform comprising:

a housing having a bore extending between first and second ends;

a first retainer carried at the first end of the housing adapted for releasably latching the housing to the first endform;

a second endform having a bore extending from one end;

a valve movably mounted in the bore for movement in a first direction to close the bore in housing to fluid flow and oppositely in a second direction to open flow through the bore in the housing; and

a second retainer carried by the housing for releasably latching the second endform in the housing.

14. The fluid quick connector of claim 13 wherein the second endform comprises:

a body having a through bore extending between an endform at a first end and a second end; and

a stop valve carried on the body for selectively opening and closing the bore in the body to fluid flow between the first end and the second end.

15. The quick connector of claim 13 further comprises:

means for biasing the valve in a first direction in the housing into sealing engagement with the housing.

16. The quick connector of claim 13 wherein the first retainer comprises:

means for one way slide on engagement with the first endform.

17. The quick connector of claim 16 wherein the first retainer comprises:

an annular member having a through bore mountable over the first endform and a plurality of circumferentially arranged angled spring fingers engageable with the first endform.

18. The quick connector of claim 13 further comprising:

a carrier mountable in the first end of the housing, the sleeve carrying the first retainer.

19. The quick connector of claim 18 further comprising:

seal means mounted between the sleeve and the first housing for sealingly coupling the sleeve to the housing.

20. The quick connector of claim 13 where the second retainer comprises:

a bore adjacent the second end of the housing extending transversely to the bore extending between the first and second ends of the housing, the second retainer movable through the transverse bore and engageable with the second endform.

21. The quick connector of claim 20 further comprising:

a radially inwardly extending recess formed in the second endform; and

a radially outward extending projection carried by the retainer and engageable with the recess in the endform to releasably latch the retainer to the endform.

22. The quick connector of claim 13 further comprising:

at least one recess formed in the housing opening to the bore extending between the first and second ends of a housing; and

the valve operable to close off fluid communication between the recess in the housing and a remaining portion of the bore extending to the second end of the housing when in the closed position in the housing.

23. The quick connector of claim 22 wherein the valve further comprises:

at least one aperture formed in the valve and disposed in fluid flow communication with at least one recess in the housing when the valve is in first position to open fluid flow between the first and second ends of the housing.

24. The quick connector of claim 23 further comprising:

at least one recess in the housing that includes a plurality of circumferentially spaced recesses; and

at least one aperture in the valve comprises a plurality of circumferentially spaced apertures.

25. The quick connector of claim 22 further comprising:

a sleeve mounted in the bore in the housing, the at least one recess carried in the sleeve.
