Abstract

An air filter mounting plate having sealing side and a filter media retaining side, said mounting plate including an air passage opening and a gasket encircling the air passage opening provided on sealing side of the mounting plate, the gasket comprising a connection portion and double sealing lips ( 7 a, 7 b ) extending from the connection portion, and wherein the gasket is joined with the mounting plate by the connection portion being fixed on the sealing side of the mounting plate.

First claim

The invention claimed is:

1 . An air filter mounting plate having a sealing side and a filter media retaining side, said mounting plate including an air passage opening and a gasket encircling the air passage opening provided on sealing side of the mounting plate wherein the gasket comprises a connection portion and double sealing lips extending from the connection portion, and wherein the gasket is joined with the mounting plate by the connection portion being fixed on the sealing side of the mounting plate, wherein at least one stop member is located on the sealing side of the mounting plate, said stop members having an abutment surface extending further from the mounting plate than the connection portion.

2 . The air filter mounting plate of claim 1 , wherein the connection portion is fixed in a recess.

3 . The air filter mounting plate of claim 1 , wherein the gasket is attached to the mounting plate by co-injection molding.

4 . The air filter mounting plate of claim 1 , wherein the connection portion of the gasket comprises an outermost attachment portion and a waist portion located between the outermost attachment portion and the double sealing lips, and a recess on the sealing side is configured to receive the outermost attachment portion of the gasket, and has an opening, which is narrower than the outermost attachment portion of the gasket.

5 . The air filter mounting plate of claim 1 , wherein the double sealing lips extend in divergent directions from the connection portion.

6 . The air filter mounting plate of claim 1 , wherein the double sealing lips have a curved cross-sectional shape.

7 . The air filter mounting plate of claim 1 , wherein at least one rib is provided on at least one of the double sealing lips, said rib being located in a vicinity of an outward edge of a lip.

8 . The air filter mounting plate of claim 1 , further comprising one or more attachment members protruding from the sealing side of the mounting plate, said attachment members being configured to attach the mounting plate to a base plate of an air filter arrangement and wherein the gasket is located outside of the attachment members in relation to the opening.

9 . The air filter mounting plate of claim 1 , wherein at least one of the double sealing lips tapers towards an outward edge of the double sealing lips to form a sharp lip edge.

10 . The air filter mounting plate of claim 1 , wherein the sealing lips have a same height in relation to the connection portion and extend to a common plane corresponding to an abutment surface of a mounting structure.

11 . The air filter mounting plate of claim 1 , wherein the sealing lips include a first sealing lip, which is located outward of a second sealing lip in relation to the opening, and which has a greater height than the second sealing lip in relation to the connection portion.

12 . The air filter mounting plate of claim 1 , wherein the sealing lips diverge by an angle of 20-60 degrees with respect to a center line extending through the connection portion.

13 . The air filter mounting plate of claim 1 , wherein an opening is provided in one of the sealing lips, said opening having a diameter of 0.1-10 mm, and being arranged in a second sealing lip, which is located inward of a first sealing lip in relation to the air passage opening.

14 . The air filter mounting plate of claim 1 , wherein the gasket is made of non-porous rubber or rubber having a permeability value less than 3 kg per s per m 2 .

15 . The air filter mounting plate of claim 1 wherein the gasket is made of rubber of 10-100 Shore A hardness.

16 . The air filter mounting plate of claim 1 wherein the gasket is made of rubber of 25-75 Shore A hard ness.

17 . The air filter mounting plate of claim 1 wherein the gasket is made of rubber of 40-70 Shore A hardness.
