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.
Claims25
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.
A apparatus, comprising:
- an occlusion member disposed within a lumen of a housing, the occlusion member configured to pneumatically isolate a volume defined by the housing from a volume outside the housing when in a first position;
- at least one biased member defining a lumen disposed adjacent the occlusion member and configured to bias the occlusion member in its first position;
- and
- an adjustable member defining a lumen configured to retain the occlusion member and the at least one biased member within the lumen of the housing,
- the volume defined by the housing being in pneumatic communication with the volume outside the housing via the lumen of the at least one biased member and the lumen of the adjustable member when the occlusion member is in a second position.
An apparatus, comprising:
- a housing defining a cavity and a lumen;
- at least one capacitor disposed within the cavity of the housing;
- and
- a purge valve having a threaded portion, the purge valve disposed within the lumen when in a first configuration, the purge valve configured to pneumatically isolate a volume defined by the cavity from a volume outside the housing when the purge valve is in the first configuration and a pressure within the cavity is less than a predetermined pressure,
- the volume defined by the cavity being in pneumatic communication with the volume outside the housing when the purge valve is in a second configuration, the purge valve being moved from its first configuration to its second configuration by at least partially moving the threaded portion with respect to the housing.
