US Patent:

57407746, Apr 21, 1998

Filed:

Dec 18, 1996

Appl. No.:

8/768522

Inventors:

Gary Kennedy - Clarkston MI

Assignee:

Siemens Electric Limited - Tilbury

International Classification:

F02M 3504

US Classification:

123198E

Abstract:

In installed position, a filter, comprising a removable particulate filter medium, is disposed in an induction air passage in circumferentially perimetrically sealed relation with the passage side wall. The passage wall has an opening providing for a drawer to be slid into and out of the passage. The drawer has a perimeter that bounds an open center and that supports the filter in covering relation to the open center. Once the drawer has been slid into the passage sufficiently to have passed the filter completely into the passage, the filter abuts the passage wall to prevent further insertion of the filter. Thereupon, continued sliding of the drawer into the passage moves the filter transversely into perimetrically sealed relation with the passage wall, thereby constraining air to pass through the filter medium. The filter is supported in final position by underlying support surfaces on the drawer. The drawer face provides a closure for closing the passage side wall opening upon full insertion of the drawer into the passage.

International Classification:

US Classification:

Abstract:

An air filter housing including top and bottom housing portions joined by a catch. The housing portions each include a plurality of walls joined together to define an enclosure with and opening circumscribed by an edge. The edge of each portion includes a surface for contacting a seal disposed between the surfaces when the housing portions are joined to form the filter housing. The portions are joined by a hinge assembly and a catch which extends along a side of the filter housing to compress the seal between the portions to form a generally air tight seal therebetween. Typically the seal is integral with a filter element which is in an air flow path between openings in the housing portions.
