Publication number: 20100024388Abstract: The present invention discloses a flow-restricting filter capable of restricting intentionally the flow of the combustion gas from a solid propellant gas generator to an external member (for example, the nozzle) to rise up combustion pressure resulting in increasing a burning rate of the solid propellant and in reducing a burning area of the solid propellant and the overall size of the gas generator. The flow-restricting filter according to the present invention comprises a hollow member having a plurality of through holes formed thereon; and a flow-blocking plate provided at one end of the hollow member to form a space having one closed end and another opened end in the hollow member.Type: ApplicationFiled: October 31, 2008Publication date: February 4, 2010Applicant: KOREA AEROSPACE RESEARCH INSTITUTEInventors: Moon Geun HONG, Soo Yong LEE

Publication number: 20090217632Abstract: 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: ApplicationFiled: August 15, 2006Publication date: September 3, 2009Inventors: Paul R. Coulonvaux, Johan G. Dewit, Tom Hg Vranken

Patent number: 7582130Abstract: A coalescing filter assembly having an upstream chamber, a downstream chamber, and a weephole connecting the upstream chamber to the downstream chamber. The downstream chamber includes a coalescing filter to filter a flow of gases. A passageway may be implemented between the upstream chamber and the downstream chamber to accommodate the flow of gases therethrough, while the weephole enables liquid to seep from the upstream chamber to the downstream chamber. In this manner, the weephole reduces liquid pooling in the upstream chamber without substantially compromising the efficiency or performance of the coalescing filter. A drain may connect to the downstream chamber to drain liquid collected therein.Type: GrantFiled: April 14, 2006Date of Patent: September 1, 2009Assignee: Cummins Filtration IP Inc.Inventors: Kwok-Lam Ng, Roger Zoch, Brian Schwandt
