Abstract
A quick disconnect coupling for connecting a tube to another structure, such as a structure defining a port. The quick disconnect coupling may include a tube including a retention shoulder, a swivel rotatably disposed on the tube, and an adapter defining a bore for receiving a portion of the tube. The swivel may be engageable with the adapter to trap the retention shoulder between the swivel and the adapter. The adapter may be engageable with a receiving structure defining a port and the port may be in fluid communication with a lumen of the tube when the swivel is engaged with the adapter.
Claims15
A quick disconnect coupling, comprising:
- a tube including a retention shoulder;
- a swivel rotatably disposed on the tube and retained on the tube by the retention shoulder, the swivel including at least one tab projecting outwardly of the retention shoulder;
- and
- an adapter defining a bore for receiving the tube, the adapter including an internal flange dimensioned to allow passage of the retention shoulder and selective passage of the at least one tab depending on a rotational orientation of the swivel, wherein in a first rotational orientation of the swivel relative to the adapter the internal flange allows passage of the at least one tab, and wherein upon passage of the at least one tab the swivel is rotatable relative to the adapter to a second rotational orientation in which the swivel and the adapter are engaged together;
- said coupling further comprising a structure defining a port, wherein the adapter is threaded into the structure;
- and wherein
- the retention shoulder is offset from an end of the tube;
- the tube includes an outer surface extending between the end of the tube and the retention shoulder;
- the retention shoulder is disposed inside of the adapter;
- and
- the end of the tube and at least part of the outer surface are disposed inside the structure beyond the adapter.

A quick disconnect coupling, comprising:
- a tube including a retention shoulder;
- a swivel rotatably disposed on the tube and retained on the tube by the retention shoulder, the swivel including at least one tab projecting outwardly of the retention shoulder;
- and
- an adapter defining a bore for receiving the tube, the adapter including an internal flange dimensioned to allow passage of the retention shoulder and selective passage of the at least one tab depending on a rotational orientation of the swivel, wherein in a first rotational orientation of the swivel relative to the adapter the internal flange allows passage of the at least one tab, and wherein upon passage of the at least one tab the swivel is rotatable relative to the adapter to a second rotational orientation in which the swivel and the adapter are engaged together;
- said coupling further comprising:
- a first sealing element disposed on the tube and arranged to form a seal between the tube and a receiving structure;
- a second sealing element disposed on the swivel and arranged to form a seal between the swivel and the receiving structure;
- and
- a third sealing element disposed on the swivel and arranged to form a seal between the swivel and the tube,
- wherein the adapter is disposed axially between the first sealing element and the second sealing element.

A quick disconnect coupling, comprising:
- a tube including a retention shoulder;
- a swivel rotatably disposed on the tube and retained on the tube by the retention shoulder, the swivel including an external thread projecting outwardly of the retention shoulder;
- and
- an adapter defining a bore for receiving the tube, the adapter including an internal thread dimensioned to threadedly engage the external thread of the swivel, wherein the retention shoulder is captured between the swivel and the adapter when the swivel and the adapter are threadedly engage;
- said coupling further comprising a structure defining a port, wherein the adapter is threaded into the structure;
- and wherein the retention shoulder is offset from an end of the tube;
- the tube includes an outer surface extending between the end of the tube and the retention shoulder;
- the retention shoulder is disposed inside of the adapter;
- and
- the end of the tube and at least part of the outer surface are disposed inside the structure beyond the adapter.
