Patent number: 8167968Abstract: In a vehicle having an air cleaner for cleaning incoming intake air supplied to an engine, a stepped surface is formed on at least one of a plurality of walls of an air cleaner housing. The stepped surface is formed on an upper wall of the air cleaner housing, such that an outer step is arranged on a periphery of an inner step. The upper wall is formed into a stereoscopic shape by providing the stepped surface thereon, such that the rigidity of the upper wall is enhanced, and a sonic resonance of the upper wall can be suppressed during vehicle operation, thereby reducing intake noises. By providing the stepped surface to the upper wall of the air cleaner for reducing intake noises, and it is unnecessary to add one or more extra components to the air cleaner for reducing intake noises.Type: GrantFiled: September 9, 2009Date of Patent: May 1, 2012Assignee: Honda Motor Co., Ltd.Inventors: Masatoshi Sato, Masaya Ishiguro

Patent number: 8163056Abstract: An air cleaner having a housing body and a removable cover and a filter element, in which the cover and the filter element rotationally interfere with each other by engagement between an inside surface of the cover and an outer radial periphery of the filter element. A filter element includes a pair of end caps, filter media, and an outer wall on the end cap circumscribing the filter media, in which the outer wall is non-circular. A method of installing a filter element into a housing includes orienting a cover over an element and a housing body by engaging an inside surface of the cover and an outer radial periphery of the filter element to rotationally interfere with each other.Type: GrantFiled: August 15, 2006Date of Patent: April 24, 2012Assignee: Donaldson Company, Inc.Inventors: Paul R. Coulonvaux, Johan G. Dewit, Tom Hg Vranken

Patent number: 8157880Abstract: The invention relates to a filter device (10), especially an air filter for an internal combustion engine, in which a main filter element (22) is arranged in a filter housing (12). The main filter element is flown through by a fluid to be filtered. The main filter element (22) is embodied as a multi-bellows filter having at least two radially nested filter bellows (32, 34). Between the filter bellows (32, 34) a flow space (44) for the fluid is formed communicating with an end face of the main filter element (22), wherein each one of the filter bellows (32, 34) is embodied as a star-shaped filter with filter folds arranged in a star shape. On at least one end face of the main filter element (22) there is a seal (36) between one of the filter bellows (32, 34) and the filter housing (12).Type: GrantFiled: February 26, 2009Date of Patent: April 17, 2012Assignee: Mann + Hummel GmbHInventor: Karlheinz Muenkel
