Ventilation device for motor vehicle with adjustable valve
A recently granted patent (Publication Number: US11964538B2) discloses a ventilation device designed for motor vehicles. The device includes a first supply duct and a second supply duct, each leading to a mixing section with a mixing duct. Within the mixing section, there are first and second guides with sloping guide walls that adjust a valve to control the flow of air between the supply ducts and the mixing duct. The valve, operated by an actuator, can fluidically separate the supply ducts and the mixing duct based on its position, allowing for efficient ventilation control in the vehicle.
Furthermore, the patent details additional features of the ventilation device, such as the presence of a separating wall defining the mixing duct and an additional mixing duct. The device also includes a second valve with similar adjustable guide sections and an actuator for controlling airflow in the additional mixing duct. The design of the ventilation device ensures optimal air distribution within the vehicle, with mirror-symmetric assemblies and tooth structures on the valves and actuators for precise adjustment. Overall, the patented ventilation device offers a sophisticated system for regulating airflow in motor vehicles, enhancing comfort and air quality for passengers.
