A cab for a work vehicle includes: walls enclosing a cab environment; a door coupled to one of the walls, one of the walls or the door comprising a vent opening; a heating, ventilation, and air conditioning (HVAC) system coupled to the cab environment and configured to regulate a temperature and a pressure of the cab environment; and a pressure control flap associated with the vent opening and comprising a pressure-relief opening and a magnetic portion that is configured to hold the flap closed when the pressure of the cab environment is below a threshold pressure and allow the pressure to open the flap when the pressure exceeds the threshold pressure.

This disclosure relates to a valve assembly for a motor vehicle, such as a pressure relief valve, and a method of using the same. The valve assembly includes a flap moveable to between an open position and a closed position. The valve assembly further includes a pair of shape memory-alloy (SMA) wires configured to move the flap between the open and closed positions. Specifically, the valve includes a first shape-memory alloy wire configured to rebound to a first rebound shape to urge the flap to the open position, and a second shape-memory alloy wire configured to rebound to a second rebound shape to urge the flap to the closed position.

A venting valve for venting the interior of a vehicle includes a housing having at least one passage opening, and at least one venting flap which is mounted on the housing by a pivot mounting so as to be pivotable between a closed position and an open position. In the closed position, the at least one venting flap closes off the at least one passage opening and, in the open position, opens up the at least one passage opening for an air stream from the interior of the vehicle to the outside. The pivot mounting is arranged on an inner side of the housing, which inner side, in the assembled or installed state, faces the interior of the vehicle.

A rear wall structure of a passenger compartment includes a vent opening and a horizontally extending seal protruding in a vehicle forward direction. A trim panel has a rear surface facing the rear wall structure. A vertically extending seal extends from the rear surface. With the trim panel installed to the rear wall structure the vertically extending seal contacts the rear wall structure, and, the horizontally extending seal of the rear wall structure contacts the rear surface of the trim panel such that the rear surface and the vertically extending seal of the trim panel and the upright interior surface and the horizontally extending seal of the rear wall structure define an air outlet passageway that extends from an opening in the trim panel to the vent opening.

A vehicle passenger compartment vent structure that includes a rear wall structure, a drafter vent assembly, a baffle and a trim panel. The rear wall structure defines a rearward area of a passenger compartment of a vehicle. The rear wall structure defines at least one vent opening. The drafter vent assembly is installed to the rear wall structure covering the at least one vent opening. The baffle is installed to the rear wall structure adjacent to the drafter vent assembly and is configured to dampen sound from the drafter vent assembly. The trim panel is installed to the rear wall structure contacting the baffle and concealing the drafter vent assembly.

A ventilation device for the interior compartment of a vehicle, in particular of an automobile, comprising a holding frame (10) which can be inserted into an installation opening of the vehicle, wherein the holding frame (10) forms a grille-free ventilation opening, and in that multiple ventilation flaps (18) are mounted on the holding frame (10) so as to be pivotable, about a pivot axis (20) running parallel to the center-of-gravity axis (32) thereof, between a closed position, in which they close the ventilation opening and an open position, in which they open up the ventilation opening for the purposes of ventilating the vehicle interior compartment.

A vehicle body includes a cabin portion, a bed portion, and an air extractor. The cabin portion defines a passenger cabin and includes a hollow pillar having an opening to the passenger cabin. The bed portion defines a bed and includes a hollow frame rail elongated from the pillar. The pillar and the frame rail define an airflow path from the opening. The air extractor is positioned in the frame rail and is in communication with the airflow path and an ambient environment.

A vehicle includes a vehicle body including a quarter panel assembly. The quarter panel assembly includes an inner quarter panel and an outer quarter panel located outboard of the inner quarter panel forming a volume therebetween. The outer quarter panel has a vent opening extending therethrough. A quarter vent assembly is connected to the outer quarter panel covering the vent opening. An exterior fascia covers the quarter vent assembly such that an air gap is provided between the quarter vent assembly and the exterior fascia. A service hole cover is located in the volume between the inner quarter panel and the outer quarter panel. The service hole cover includes a cover body and a noise reduction flange at a bottom of the cover body that extends inboard toward the inner quarter panel at the vent opening.

This disclosure relates to a valve assembly for a motor vehicle, such as a pressure relief valve (i.e., an air extractor), and a method of using the same. In an example, the valve assembly includes a flap moveable to between an open position and a closed position, a slider moveable along an axis and including an integrally formed arm in contact with the flap, and an electromagnet configured to be selectively activated to move the slider along the axis.
