Abstract
The present disclosure is generally related to vent assemblies. More particularly, the present disclosure is related to vent assemblies that are configured for pressure equalization of an enclosure.
Claims8
A vent assembly comprising:
- a vent body defining a cavity, a first axial end, a second axial end, wherein the vent body comprises a coupling structure towards the second axial end;
- an outlet relief valve selectively sealed to the vent body within the cavity, wherein the outlet relief valve selectively defines an outlet airflow pathway upon a first pressure differential between the first axial end and the second axial end;
- an inlet relief valve selectively sealed to the vent body within the cavity, wherein the inlet relief valve selectively defines an inlet airflow pathway upon a second pressure differential between the first axial end and the second axial end, wherein the outlet relief valve and the inlet relief valve are arranged in parallel relative to airflow through the vent body;
- and
- a passive airflow vent disposed in the vent body, wherein the passive airflow vent is arranged in series with the inlet relief valve and the passive airflow vent is arranged in parallel with the outlet relief valve, wherein the vent assembly lacks a passive airflow vent in series with the outlet relief valve,
- wherein the vent body forms a cover between the passive airflow vent and an environment outside of the vent body, wherein the cover surrounds the passive airflow vent laterally outward from the passive airflow vent and axially outward from the passive airflow vent, wherein the cover is positioned towards the first axial end.

A vent assembly comprising:
- a vent body defining a cavity, a first axial end, and a second axial end, wherein the vent body comprises a base portion and a coupling structure towards the second axial end;
- an outlet relief valve selectively sealed to the vent body within the cavity, wherein the outlet relief valve selectively defines an outlet airflow pathway upon a first pressure differential between the first axial end and the second axial end;
- an inlet relief valve selectively sealed to the vent body within the cavity, wherein the inlet relief valve selectively defines an inlet airflow pathway upon a second pressure differential between the first axial end and the second axial end, wherein the outlet relief valve and the inlet relief valve are arranged in parallel relative to airflow through the vent body;
- a passive airflow vent disposed in the vent body, wherein the passive airflow vent is arranged in series with the inlet relief valve and the passive airflow vent is arranged in parallel with the outlet relief valve, wherein the vent assembly lacks a passive airflow vent in series with the outlet relief valve, wherein the vent body forms a cover between the passive airflow vent and an environment outside of the vent body, wherein the cover surrounds the passive airflow vent laterally outward from the passive airflow vent and axially outward from the passive airflow vent, wherein the cover is positioned towards the first axial end;
- and
- a non-breathable rupture valve disposed across a rupture valve opening defined by the vent body, wherein the non-breathable rupture valve is arranged in parallel with the inlet relief valve and the outlet relief valve.
