Abstract

A fluid connection assembly, including a service valve body, including a first section forming a first port and a second port, a second section connected to the first section and forming a third port, a connector body forming a fourth port and including a first end connected to the first section, a second end, a first radially outward facing surface including an annular groove, and a first radially inward facing surface.

Claims (39)

1. A fluid connection assembly, comprising:

a service valve body, including:

a first section forming a first port and a second port;

a second section connected to the first section and forming a third port;

a connector body forming a fourth port and comprising:

a first end connected to the first section;

a second end;

a first radially outward facing surface comprising an annular groove; and

a first radially inward facing surface; and

a retainer, including:

a third end operatively arranged to be removably connectable to the connector body;

a fourth end;

a third section;

a fourth section displaceable with respect to the third section;

a second radially inward facing surface comprising:

a first flange extending radially inward proximate the third end and operatively arranged to engage the annular groove; and

a second flange extending radially inward proximate the fourth end; and

a second radially outward facing surface.

2. The fluid connection assembly as recited in claim 1 , wherein the first radially inward facing surface comprises at least one annual groove.

3. The fluid connection assembly as recited in claim 2 , wherein the at least one annular groove comprises:

a first annular groove; and

a second annular groove spaced apart in an axial direction from the first annular groove.

4. The fluid connection assembly as recited in claim 2 , wherein a seal is arranged in the at least one annular groove.

5. The fluid connection assembly as recited in claim 1 , further comprising a flange fixedly secured to the first section proximate the second port.

6. The fluid connection assembly as recited in claim 5 , wherein

the flange comprises a through-hole spaced apart from the second port.

7. The fluid connection assembly as recited in claim 1 , wherein:

the first port and the second port are concentrically aligned; and/or

the third port and the fourth port are concentrically aligned.

8. The fluid connection assembly as recited in claim 1 , wherein at least one of the second section and the connector body are arranged perpendicular to the first section.

9. The fluid connection assembly as recited in claim 1 , wherein at least one of the first section and the second section comprises radially outward facing threading.

10. The fluid connection assembly as recited in claim 1 , wherein:

the first flange comprises a first diameter;

the second flange comprises a second diameter; and

the first diameter is greater than the second diameter.

11. The fluid connection assembly as recited in claim 1 , further comprising a tube including a shoulder, wherein the second flange is operatively arranged to engage the shoulder to secure the tube in the connector body.

12. The fluid connection assembly as recited in claim 11 , wherein the shoulder resides completely outside of the connector body when the tube is secured to the connector body.

13. The fluid connection assembly as recited in claim 11 , wherein the shoulder engages the second end when the tube is secured to the connector body.

14. The fluid connection assembly as recited in claim 11 , wherein the shoulder abuts against the second end when the tube is secured to the connector body.
