Abstract
A vehicle interior ventilation apparatus having at least one pressure relief valve, in particular of a first type, which is received and/or fixed in a first receiving opening in a vehicle body component, and having at least one pressure relief valve (10), in particular of a second type that differs from the first type, which is received and/or fixed in a second receiving opening separated from the first receiving opening in a vehicle body component.
Claims17
A vehicle interior ventilation apparatus having at least one pressure relief valve, of a first type, which is received and/or fixed in a first receiving opening in a vehicle body component and is arranged to allow an airflow from an interior of the vehicle to pass outwardly from the interior of the vehicle via the vent opening, and having at least one pressure relief valve, of a second type that differs from the first type, which is received and/or fixed in a second receiving opening separated from the first receiving opening in a vehicle body component and is arranged to allow an airflow from an interior of the vehicle to pass outwardly from the interior of the vehicle via the vent opening, wherein the valve of the first type is a pivoting flap type valve and the valve of the second type is poppet or ball check valve.
A vehicle interior ventilation apparatus having at least one pressure relief valve, of a first type, which is received and/or fixed in a first receiving opening in a vehicle body component and is arranged to allow an airflow from an interior of the vehicle to pass outwardly from the interior of the vehicle via the vent opening, and having at least one pressure relief valve, of a second type that differs from the first type, which is received and/or fixed in a second receiving opening separated from the first receiving opening in a vehicle body component and is arranged to allow an airflow from an interior of the vehicle to pass outwardly from the interior of the vehicle via the vent opening,
- wherein the at least one pressure relief valve of the first type has a response behavior that differs from a response behavior of the at least one pressure relief valve of the second type,
- wherein the at least one pressure relief valve of the first type is configured as a proportional valve, whose opening behavior is proportionate or at least substantially proportionate to the differential pressure between the vehicle interior and the external atmosphere between a range of a response differential pressure up to full opening, and wherein the at least one pressure relief valve of the second type is configured as a full stroke valve, which opens suddenly and with a full stroke upon response.
A vehicle interior ventilation apparatus having at least one pressure relief valve, of a first type, which is received and/or fixed in a first receiving opening in a vehicle body component and is arranged to allow an airflow from an interior of the vehicle to pass outwardly from the interior of the vehicle via the vent opening, and having at least one pressure relief valve, of a second type that differs from the first type, which is received and/or fixed in a second receiving opening separated from the first receiving opening in a vehicle body component and is arranged to allow an airflow from an interior of the vehicle to pass outwardly from the interior of the vehicle via the vent opening,
- wherein only the at least one pressure relief valve of the first type is provided with a cover forming a muffler space.
