Abstract
The invention is directed to an adapter comprising a rigid base portion defining an outlet, and a head portion defining an inlet. The head portion is configured for removable attachment to the rigid base portion such that a gas flow passage is provided between the inlet and the outlet when the head portion is attached to the rigid base portion. The adapter is configured to provide a first flow restriction for restricting gas flow through the gas flow passage, and an access passage to the gas flow passage. The access passage is provided downstream of the first flow restriction.
Claims43
An adapter comprising
- a rigid base portion defining an outlet, and
- a head portion defining an inlet, the head portion being configured for removable attachment to the rigid base portion such that a gas flow passage is provided between the inlet and the outlet when the head portion is attached to the rigid base portion,
- wherein the adapter is configured to provide
- a first flow restriction for restricting gas flow through the gas flow passage, and
- an access passage to the gas flow passage, the access passage being provided downstream of the first flow restriction.
The adapter according to any one of the preceding claims, wherein the first flow restriction is provided at the inlet.
The adapter according to any one of the preceding claims, wherein the head portion is tethered to the rigid base portion.
The adapter according to any one of the preceding claims, wherein the head portion is tapered.
The adapter according to any one of the preceding claims, wherein the head portion is configured for sealing engagement with a connector associated with a pressure valve.
The adapter according to any one of the preceding claims, wherein the rigid base portion includes one or more projections for engagement with one or more corresponding recesses provided by the head portion, for removable attachment thereto.
The adapter according to any one of the preceding claims, further comprising
- a second head portion configured for removable attachment to the rigid base portion, the second head portion defining an inlet such that a gas flow passage is provided between the inlet of the second head portion and the outlet of the rigid base portion when the second head portion is attached to the rigid base portion,
- wherein the adapter is configured to provide a second flow restriction for restricting gas flow through the gas flow passage when the second head portion is attached to the base portion, and
- wherein the second flow restriction is different to the first flow restriction.
An adapter comprising
- a hollow body defining an inlet and an outlet configured to provide a gas flow passage therethrough,
- a flow restriction configured to restrict gas flow through the gas flow passage,
- an access passage to the gas flow passage, the access passage being provided downstream of the flow restriction, and
- an attachment portion proximate the outlet configured for removable attachment to a rigid adapter base portion.
An adapter comprising
- a hollow body defining an inlet and an outlet for providing a gas flow passage therethrough,
- a flow restriction for restricting gas flow through the gas flow passage,
- an access passage to the gas flow passage, the access passage being provided downstream of the flow restriction, and
- a mounting portion proximate the outlet for removable mounting to a second like adapter.
An adapter comprising
- a hollow body defining an inlet and an outlet configured to provide a gas flow passage therethrough,
- a flow restriction configured to restrict gas flow through the gas flow passage,
- wherein the flow restriction is adjustable.
