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 sealably 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 the first fluid flow pathway is towards the first end;
- and
- a one-way relief valve disposed in the housing and forming a seal over the valve opening wherein the one-way relief valve is configured to relieve pressure from the second end towards the first end,
- wherein the one-way relief valve is arranged in parallel with the passive airflow vent with respect to airflow through the housing, wherein the passive airflow vent and the one-way relief valve share a central axis, and wherein the valve opening comprises a plurality of openings defining a segmented annulus about the central axis, and
- wherein the fluid flow pathway defines a tortuous path between the housing opening and the one-way relief valve.
