Abstract
An O-ring membrane valve, including an O-ring, and a resealable membrane connected to the O-ring, the resealable membrane including a first surface, a second surface, and a slit extending from the first surface to the second surface. The O-ring membrane valve may be assembled with a fluid connector, the fluid connector including a body, having a first through-bore and a first groove arranged circumferentially within the first through-bore.
Claims20
1:
- An O-ring membrane valve, comprising:
- an O-ring;
- and,
- a resealable membrane connected to the O-ring, the resealable membrane including:
- a first surface;
- a second surface;
- and,
- a slit extending from the first surface to the second surface.
5 more elements
2:
- The O-ring membrane valve as recited in claim 1, wherein the resealable membrane is conical and comprises a vertex.
3:
- The O-ring membrane valve as recited in claim 2, wherein the slit arranged at least partially on the vertex.
4:
- The O-ring membrane valve as recited in claim 1, wherein the O-ring and the resealable membrane comprise an elastomer.
5:
- The O-ring membrane valve as recited in claim 4, wherein the O-ring has a round cross-sectional geometry.
6:
- The O-ring membrane valve as recited in claim 5, wherein the O-ring has a torus geometry.
7:
- The O-ring membrane valve as recited in claim 1, wherein the O-ring is arranged to be assembled in a body of a fluid connector.
8:
- The O-ring membrane valve as recited in claim 7, wherein when the first surface is exposed to a force created by a fluid pressure, the slit is in a sealed state.
9:
- The O-ring membrane valve as recited in claim 8, wherein when a tube is inserted in the body of the fluid connector and engages the second surface, the membrane is elastically deformed and the slit is in an unsealed state.
10:
- A fluid connector, comprising:
- a body, including:
- a first through-bore;
- and,
- a first groove arranged circumferentially within the first through-bore;
- and,
- an O-ring membrane valve arranged in the first groove, the O-ring membrane valve including:
- an O-ring;
- and,
- a resealable membrane connected to the O-ring, the resealable membrane having a slit.
7 more elements
11:
- The fluid connector as recited in claim 10, wherein the resealable membrane is conical and comprises a vertex, the slit arranged at least partially on the vertex.
12:
- The fluid connector as recited in claim 10, wherein the O-ring has a round cross-sectional geometry.
13:
- The fluid connector as recited in claim 10, wherein the O-ring has a torus geometry.
14:
- The fluid connector as recited in claim 10, wherein the body further comprises:
- a radially outward facing surface having a second groove;
- and,
- a snap ring arranged in the second groove.
1 more element
15:
- The fluid connector as recited in claim 10, wherein the body is arranged for connection to a component to be filled with a fluid and the O-ring membrane valve is arranged to seal the fluid within the component.
16:
- The fluid connector as recited in claim 15, wherein:
- in a sealed state, the fluid exerts a force on the membrane such that the slit is sealed shut;
- and,
- in an unsealed state, a tube is inserted into the body to deform the membrane such that the slit is opened and the fluid may flow into or out of the component.
1 more element
17:
- The fluid connector as recited in claim 16, wherein the tube is a tube end form, comprising:
- a second through-bore;
- a radially outward facing surface arranged to displace the membrane and open the slit;
- and,
- a shoulder arranged to lock into the body.
2 more elements
18:
- The fluid connector as recited in claim 17, wherein when the tube end form is fully engaged in the body:
- the radially outward facing surface compresses the O-ring in the first groove;
- the slit is fully opened and concentrically arranged around the radially outward facing surface;
- the shoulder is locked into the body;
- and,
- the fluid connector is in an unsealed state.
3 more elements
19:
- The fluid connector as recited in claim 16, wherein the tube is a probe, comprising:
- a second through-bore;
- and,
- a radially outward facing surface arranged to displace the membrane and open the slit.
1 more element
20:
- A seal membrane valve, comprising:
- a seal;
- and,
- a resealable membrane connected to the seal, the resealable membrane including:
- a first surface;
- a second surface;
- and,
- a slit extending from the first surface to the second surface.
