Abstract
The present disclosure relates to filter assemblies. The features described and characterized are typically applied in gas (for example, air) cleaner assemblies. A typical use is in air cleaner assemblies for vehicles or other equipment. The techniques described relate, at least in part, to provision of assemblies with preferred configurations for convenient servicing and operation, while ensuring a proper cartridge is appropriately positioned, oriented and secured for use. Many of the techniques relate to arrangements in which features at opposite ends of a housing and/or cartridge are eccentrically positioned as described.
Claims26
An air filter cartridge comprising:
- (a) a filter media surrounding an open filter interior;
- (i) the filter media having first and second ends;
- (b) a first end piece positioned at the first end of the filter media;
- (i) the first end piece having a flow aperture therethrough;
- (c) a housing seal arrangement comprising a releasable seal positioned on the first end piece including a non-circular radially directed seal member;
- (d) a second end piece positioned at the second end of the filter media;
- (i) the second end piece is closed, and has no aperture therethrough, in direct flow communication with the open filter interior;
- (ii) the second end piece includes a receiver projection extending into the open filter interior a distance, from the filter media second end toward the filter media first end, corresponding to at least 15% of a distance from the filter media second end to the filter media first end;
- (A) the receiver projection defining a receiver recess at an opposite side thereof, from the open filter interior;
- (e) the filter media first end defining a first media outer perimeter at a location adjacent the first end piece;
- and,
- (f) the filter media second end defining a second media outer perimeter at a location adjacent the second end piece;
- (i) the first and second media outer perimeters being eccentrically aligned with respect to one another.
