Abstract: Disclosed is a product that may include a barrel airflow volume control system, for a vehicle, including a first barrel door and a second barrel door operatively connected together so that the first barrel door and the second barrel door move away from each other to provide an air passageway opening therebetween, and move toward each other to reduce or close the air passageway opening between the first barrel door and the second barrel door.

Abstract: A vent system for a motor vehicle includes a vent conduit defining a vent conduit inlet. A vent outlet is separated from the vent conduit inlet. A first vent channel includes a first vent channel inlet in fluid communication with the vent conduit inlet and a first channel nozzle defining a first fluid flow path to the vent outlet along a first direction. A second vent channel includes a second channel inlet in fluid communication with the vent conduit inlet and a second channel nozzle defining a second fluid flow path to the vent outlet along a second direction convergent with the first direction.

Abstract: A vent assembly of a vehicle includes a bezel defining a vent opening through which an airflow is directed. A primary vane extends across the vent opening and is movable about a primary vane axis to adjust an airflow direction in a first direction. A plurality of secondary vanes are arrayed across the vent opening and are movable about a secondary vane to adjust the airflow direction in a second direction. A primary adjustment knob is located on an adjustment shaft and is rotatable about an adjustment axis. The primary adjustment knob is configured to effect movement the primary vane about the primary vane axis. A secondary adjustment knob is coaxial with the primary adjustment knob and is independently rotatable about the adjustment axis. The secondary adjustment knob is configured to effect movement of the plurality of secondary vanes about their respective secondary vane axes.

Abstract: A pressure relief valve includes a housing configured for installation into a duct opening of a duct, and a diffuser installed into the housing and movable between a closed position and an opened position along a valve axis. The diffuser includes a tubular diffuser body having an inlet opening at a first end, a diffuser cap located at a second end of the tubular diffuser body to close the tubular diffuser body at the second end, and one or more outlet openings located between the inlet opening and the diffuser cap. A biasing element biases a position of the diffuser toward the closed position. When an airflow pressure in the duct exceeds a threshold, the airflow urges the diffuser toward the opened position thus allowing the airflow to exit the pressure relief valve at the one or more outlet openings.

Abstract: A vent assembly of a vehicle includes a vent having a vent opening through which an airflow is directed, and a primary duct operably connected to the vent to convey the airflow toward the vent opening. A pressure relief valve is located along the primary duct. The pressure relief valve is configured to open when a pressure of the airflow in the primary duct exceeds a threshold, to divert a portion of the airflow through the pressure relief valve.
