Patent number: 8080078Abstract: An anti-snow module designed for installation into an air filter housing includes a support plate configured for support in the housing. A partition is provided for mounting into the interior of the housing of the air filter. A valve plate is configured to seals the housing of the air filter below a predetermined differential pressure existing between the interior of the housing of the air filter behind the valve plate and the exterior of the housing of the air filter and open when the differential pressure exceeds a predetermined differential pressure value. At least one guide rail is provided on which the valve plate is slideably supported by at least one guide sleeve provided on the valve plate.Type: GrantFiled: December 11, 2008Date of Patent: December 20, 2011Assignee: Mann+Hummel GmbHInventors: Robert Zbiral, Herbert Schenk, Dagmar Ruder

Patent number: 8048182Abstract: Embodiments of the invention generally provide a containment system having integrated bubble tight-dampers. In another embodiment, the containment system includes an integral auto-scan mechanism disposed in the housing of the containment system so that a filter element, disposed in the housing, may be leak tested without accessing the interior of the housing. In yet another embodiment, a method for testing a filter disposed in a containment system includes challenging an upstream side of a filter element disposed in a housing of the containment system with a test aerosol, and automatically moving a probe disposed within the housing to obtain samples for leak testing.Type: GrantFiled: January 17, 2011Date of Patent: November 1, 2011Assignee: Camfil Farr, Inc.Inventors: Thomas C. Morse, Mark Huza

Patent number: 8043395Abstract: The present invention generally relates to a motor vehicle air cleaner assembly that is field or end user convertible to another variety of air cleaner having secondary air induction. The air cleaner is pre-configured to enable a field modification to provide for secondary air induction for admitting heated secondary air to the air cleaner and air filter to aid in melting snow or ice blockage of the air filter and permitting the vehicle to operate in snow and ice air filter blockage conditions.Type: GrantFiled: January 28, 2009Date of Patent: October 25, 2011Assignee: Mann + Hummel GmbHInventor: Alex Braithwaite

Patent number: 8038770Abstract: A separator for a hydraulic system is provided, including a substrate and a membrane. The substrate includes a substrate outer surface and a gas side expulsion area. The expulsion area is for expelling gas from the separator. The membrane is in communication with the substrate, and is for permeating gas to the substrate outer surface while substantially blocking ingression of fluid to the substrate. The substrate outer surface is for receiving gas. The substrate is for transporting gas from the substrate outer surface to the expulsion area.Type: GrantFiled: December 1, 2008Date of Patent: October 18, 2011Assignee: Eaton CorporationInventor: Edward J. Hummelt
