Abstract
In some embodiments, an apparatus includes a housing and a purge valve. The housing defines a cavity and a lumen extending from a volume of the cavity to a volume outside the cavity. The purge valve is disposed within the lumen and includes an occlusion member. A portion of the occlusion member has a width substantially equal to a width of an end portion of the lumen such that the portion of the occlusion member is disposed within the end portion of the lumen when the purge valve is in a first configuration. The portion of the occlusion member being disposed outside the end portion of the lumen when the purge valve is in a second configuration.
Claims29
An apparatus, comprising:
- a housing defining a cavity and a lumen extending from a volume of the cavity to a volume outside the cavity, a first end portion of the lumen having a width and a second end portion of the lumen having a width less than the width of the first end portion, the second end portion of the lumen being adjacent the volume of the cavity, the first end portion being adjacent the volume outside the cavity;
- and
- a purge valve removably coupled to the housing and disposed at least partially within the lumen, the purge valve including an occlusion member, a portion of the occlusion member having a width substantially equal to the width of the second end portion of the lumen such that the portion of the occlusion member is disposed within the second end portion of the lumen when the purge valve is in a first configuration, the portion of the occlusion member being disposed outside the second end portion of the lumen when the purge valve is in a second configuration,
- wherein the purge valve includes an adjustable member configured to retain the occlusion member within the lumen of the housing, the adjustable member having a plurality of threads configured to mate with a plurality of threads of the housing to couple the adjustable member to the housing, the adjustable member configured to be unscrewed from the housing to release a pressure within the cavity of the housing.

An apparatus, comprising:
- a housing defining a cavity and a lumen extending from a volume of the cavity to a volume outside the cavity, a first end portion of the lumen having a width and a second end portion of the lumen having a width less than the width of the first end portion, the second end portion of the lumen being adjacent the volume of the cavity, the first end portion being adjacent the volume outside the cavity;
- and
- a purge valve removably coupled to the housing and disposed at least partially within the lumen, the purge valve including an occlusion member, a portion of the occlusion member having a width substantially equal to the width of the second end portion of the lumen such that the portion of the occlusion member is disposed within the second end portion of the lumen when the purge valve is in a first configuration, the portion of the occlusion member being disposed outside the second end portion of the lumen when the purge valve is in a second configuration,
- wherein the purge valve includes a biased member having a first position and a second position, the biased member disposed adjacent the occlusion member, the biased member being biased in its first position,
- the biased member being in its first position and retaining the occlusion member within the second end portion of the lumen of the housing when the purge valve is in the first configuration,
- the purge valve moving from its first configuration to its second configuration when a pressure within the cavity causes the occlusion member to move the biased member from its first position to its second position allowing pneumatic communication between the volume of the cavity and the volume outside the cavity, the biased member returning to its first position when the pressure within the cavity returns below a predetermined threshold.
