Abstract
A vent assembly has a base and a single piece cover that is attached to the base to form a housing. A partition inside the housing forms an upper compartment that communicates with an outlet at the rear of the cover and a lower compartment that communicates with an inlet through the base. The compartments communicate via an opening through the partition. The partition provides an exhaust passage from the opening to the outlet at the rear of the cover and a barrier to the flow of water from the outlet back to the opening. The partition and cover provide a drain passage from the exhaust passage back to the outlet in case water accumulates near the opening. The vent assembly may be static or include a fan unit to provide a powered vent assembly. Either may be used as the hatch of a combined vent and escape hatch assembly.
