Abstract
A vent assembly has a housing defining a cavity, a first end, a second end, a vent opening, a valve opening, and a coupling structure towards the second end. The housing defines a valve opening and a vent opening. A vent is coupled to the housing across the vent opening, and a one-way relief valve is scalably disposed on the housing across a valve opening.
Claims20
A vent assembly comprising:
- a housing defining a cavity, a first end, a second end, a vent opening, a valve opening, and a coupling structure towards the second end;
- a passive airflow vent disposed in the housing across the vent opening, wherein the housing defines a housing opening between an ambient environment and the cavity to define a first fluid flow pathway between the ambient environment and the passive airflow vent;
- and
- a one-way relief valve disposed in the housing and forming a seal over the valve opening,
- wherein the vent assembly lacks a breathable membrane across the valve opening,
- wherein the passive airflow vent and the one-way relief valve share a central axis,
- wherein the coupling structure defines a second fluid flow pathway between an outside of the housing and the passive airflow vent, wherein the first fluid flow pathway and the second fluid flow pathway are in selective fluid communication through the one-way relief valve, and wherein the first fluid flow pathway and the second fluid flow pathway are in constant fluid communication through the passive airflow vent.

A vent assembly comprising:
- a housing defining a cavity, a first end, a second end, a vent opening, a valve opening, and a coupling structure towards the second end, wherein the housing defines a housing opening between an ambient environment and the cavity, the housing opening proximate the first end;
- a passive airflow vent disposed in the housing across the vent opening, wherein the housing comprises a first obstruction positioned between the ambient environment and the passive airflow vent, wherein the first obstruction creates a tortuous path between the ambient environment and the passive airflow vent;
- and
- a one-way relief valve disposed in the housing and forming a seal over the valve opening,
- wherein the passive airflow vent and the one-way relief valve share a central axis, wherein the valve opening comprises a plurality of openings defining a segmented annulus about the central axis,
- wherein the coupling structure defines a coupling structure opening between an outside of the housing and the passive airflow vent, wherein the housing opening and the coupling structure opening are in selective fluid communication through the one-way relief valve, and wherein the housing opening and the coupling structure opening are in constant fluid communication through the passive airflow vent.
