Connector for transferring fluid and method of use
A connector for transferring fluid and method therefor. The connector may have a first port and a second port which may be coupled together at a main channel with a valve element therein controlling fluid flow through the first port. The first port joins the main channel to provide a fluid path around the valve element and through the second port.
1. A connector for transferring fluid, the connector comprising:
a housing comprising a base having a first port, and a cap having a second port, the base and cap defining a channel that extends between the first and second ports; and
a valve element comprising a body, a head, and a longitudinal axis between the body and the head, the body having a wall with an inner surface defining an internal chamber, and the head coupled to the body and having a first notch and a second notch, wherein the first and second notches are positioned on opposite surfaces of the head and define a reduced cross-sectional portion of the head between the first and second notches, and wherein the valve element is positioned within the channel with the head within the second port.
2. The connector of claim 1 , wherein the body comprises a third notch.
3. The connector of claim 2 , wherein a fourth notch and a fifth notch extend along an inner surface of the wall.
4. The connector of claim 3 , wherein the fourth and fifth notches extend along opposite surfaces of the inner surface of the wall.
5. The connector of claim 3 , wherein the fourth and fifth notches are axially offset along the longitudinal axis.
6. The connector of claim 1 , wherein the first and second notches comprise a common width and a common depth.
7. The connector of claim 1 , wherein the first and second notches have a depth that extends transverse to the longitudinal axis, and the first notch has a first depth and the second notch has a second depth that is less than the first depth.
8. The connector of claim 1 , wherein the first and second notches have a width that extends along the longitudinal axis, and the first notch has a first width and the second notch has a second width that is less than the first width.
9. The connector of claim 1 , wherein the first notch is longitudinally offset, relative to the second notch, along the longitudinal axis.
10. The connector of claim 1 , wherein the reduced cross-sectional portion comprises a maximum thickness that is between thirty percent and fifty percent of a diameter of the head.
11. The connector of claim 1 , wherein the base comprises a flange configured to be retained between the base and the cap to seal the internal chamber and separate the channel into an air chamber in fluid communication with an outside of the connector via a passage of the base, and a liquid chamber continuously coupled to the first port.
12. The connector of claim 1 , wherein the valve element comprises a first position and a second position within the channel, the head configured to seal the second port when the valve element is in the first position.
13. A connector for transferring fluid, the connector comprising:
a housing comprising a first port, a second port, and a channel that extends between the first and second ports; and
a valve element positioned within the channel, the valve element comprising:
a head having an outer surface comprising a first diameter, a first notch, and a second notch, and a reduced cross-sectional portion defining a thickness between the first and second notches, wherein the first and second notches are positioned on opposite surfaces of the head;
a body coupled to the head, the body having a wall with an outer surface defining a second diameter, and an inner surface defining an internal chamber; and
a longitudinal axis extending between the body and the head, wherein the thickness between the first and second notches is less than the first and second diameters.
14. The connector of claim 13 , wherein the inner surface of the body comprises a third notch.
15. The connector of claim 14 , wherein the third notch is axially offset along the longitudinal axis, relative to any of the first and second notches.
16. The connector of claim 13 , wherein the first and second notches have a depth that extends transverse to the longitudinal axis, and the first notch has a first depth and the second notch has a second depth that is less than the first depth.
17. The connector of claim 13 , wherein at least one profile of the first and second notches comprises a constant radius.
18. The connector of claim 13 , wherein the first notch is longitudinally offset, relative to the second notch, along the longitudinal axis.
19. The connector of claim 13 , wherein the thickness of the reduced cross-sectional portion is between thirty percent and fifty percent of the first diameter.
20. The connector of claim 13 , wherein the valve element comprises a first position and a second position within the channel, the head configured to seal the second port when the valve element is in the first position.
