Vent with relief valve

Abstract:

A vent assembly has a housing defining a cavity, a first end, a second end, and a coupling structure towards the second end. A mounting surface is positioned between the first end and the second end within the cavity and defines a valve opening and a vent opening. A vent is coupled to the mounting surface across the vent opening, and an umbrella valve is sealably disposed on the mounting surface across a valve opening.
