Claims14
A vent assembly comprising:
- a housing defining a cavity, a first end, a second end, and a coupling structure towards the second end;
- a mounting surface positioned between the first end and the second end within the cavity, the mounting surface defining a valve opening and a vent opening;
- a passive airflow vent disposed across the vent opening;
- and an umbrella valve sealably disposed on the mounting surface across the valve opening, wherein the umbrella valve is arranged in parallel with the passive airflow vent with respect to airflow through the housing wherein the housing further defines a central axis extendin from the first end to the second end, and wherein the mounting surface is about the central axis;
- wherein the housing defines radial openings about the central axis, wherein the radial openings define a fluid flow pathway between the outside of the housing and the passive airflow vent;
- wherein the passive airflow vent and the umbrella valve are concentric.
