Abstract

The filter on the fresh-air fan of a motor car consists of a housing which can be flange-mounted on the end pipe of the fresh-air feed and is provided with a filter which is firmly held between two perforated discs, one perforated disc being provided with a screw thread and being removable by screwing for exchange of the filter. In another embodiment it is provided to design the end pipe piece of the fresh-air feed directly as a filter housing with filter. The object is to filter the exhaust gases of the motor car ahead, particularly when driving in queues, as they enter one's own motor car and to make them less harmful.

Description

"Filter am Frischluftgebläse am PkW.""Filter on the fresh air blower on the car."

Die Erfindung betrifft einen Filter am Frischluft= gebläse von PkWs.The invention relates to a filter on the fresh air = blower of cars.

Durch den imensen Autoverkehr sind die Verkehrsstraßen voll von Abgasen. Ganz schlimm ist es, wenn man im kilometerlangen Stau fahren muß, wobei vom Verderauto viel Abgase in das dahinderfahrende Auto gelangen über die Frischluftanlagedes Autos.Due to the heavy traffic, the roads are full of exhaust fumes. It's really bad when you have to drive in a mile-long traffic jam, with the Verderauto a lot of exhaust gases get into the driving car through the fresh air system of the car.

Dies zu mldern ist Sinn vorliegender Erfindung.It is the purpose of the present invention to report this.

Zu diesem Zweck ist vorgesehen, die Frischluftanlage des Autos mit einem einem Filtergehäuse und Filter zu versehen, ähnlich wie bei einer Gasmaske.For this purpose it is intended to use the fresh air system of the car to provide a filter housing and filter, similar to a gas mask.

Das Filtergehäuse ist so ausgebildet, daß es leicht an das Frischluf tzufuh r rohr des Autos angeschlossen werden kann, bzw. es kann das Frischluftzufuhrrohr direkt als Filtergehäuse ausgebildet sein.The filter housing is designed so that it can easily be connected to the fresh air The car's supply pipe can be connected, or the fresh air supply pipe can be connected direct be designed as a filter housing.

Durch diese Maßnahme kann das über die Frischluftan= lage in das Auto einringende, schädliche Abgas gemil= dert werden, da ja zuweilen dem Autofahrer Kopfschmerzen verursacht.With this measure, this can be done via the fresh air system in the car ingressing, harmful exhaust gases are mitigated, since sometimes the car driver Causes a headache.

Die Zeichnung veranschaulicht die Erfindung in bei spielsweiser Ausführung. Es zeigen: Fig.l das Endstück einer Frischluftzuführung, Fig.2 das Filtergehäuse im Längsschnitt.The drawing illustrates the invention in example execution. They show: Fig.l the end piece of a fresh air supply, Fig.2 the filter housing in longitudinal section.

Das Rohr 1 mit Klappe 2 der Frischluftzuführung ist mit einem Flansch 3 versehen. Das Filtergehäuse 4 hat einen gleichen Flansch 5, die beide miteinander ver= bindbar sind, unter Zwischenlage einer Dichtung 6.The pipe 1 with flap 2 of the fresh air supply is with a flange 3 provided. The filter housing 4 has an identical flange 5, both of them with each other can be connected, with a seal 6 in between.

Im vorderen Ende des Filtergehäuses 4 ist ein Filter 7 zwischen zwei Lochscheiben 8, 9 vorgesehen, das die Wir= kung ähnlich einer Gasmaske hat. Die Lochscheibe 9 ist mit einem Gewinderand versehen, der sich auf das gleiche Innengewinde des Gehäuses 4 schrauben fäßt, und den Filter 7 leicht auswechselbar im Gehäuse 4 fest= hält. Das vorhandene Gebläse bleibt dabei unverändert.In the front end of the filter housing 4, a filter 7 is between two Perforated disks 8, 9 are provided, which has the effect similar to a gas mask. the Perforated disc 9 is provided with a thread edge that is on the same internal thread of the housing 4 screws, and the filter 7 easily replaceable in the housing 4 firmly = holds. The existing fan remains unchanged.

Natürlich kann das Endrohr der Frischluftzuführung direkt als Filtergehäuse Ausgebaut sein.Of course, the end pipe of the fresh air supply can be used directly as a filter housing Be developed.
