Patent number: 11826688Abstract: A filter device is provided with a filter housing and a filter element arranged in the filter housing. The filter element is provided with an annular filter medium body that has an inflow side. The filter housing has a dirt collecting region in flow communication with the inflow side of the annular filter medium body. The dirt collecting region has an annular circumferentially extending configuration. A flow-tight separation element is arranged at or adjacent to the annular filter medium body. The dirt collecting region adjoins the flow-tight separation element. An inflow region is positioned at the inflow side of the annular filter medium body and immediately adjoins the dirt collecting region. The dirt collecting region has a radial extension relative to a longitudinal axis of the annular filter medium body, and the radial extension of the dirt collecting region is larger than a radial extension of the inflow region.Type: GrantFiled: July 22, 2020Date of Patent: November 28, 2023Assignee: MANN+HUMMEL GmbHInventors: Mario Rieger, Pedro Miguel Pereira Madeira, Stefan Kunze, Ulrich Dehnen, Johannes Stuerner, Markus Beylich

Patent number: 11471807Abstract: A filter housing for a filter device is provided with an inlet housing arranged upstream of a filter element. The inlet housing has an inflow opening for introducing a fluid to be purified into the filter housing. The inlet housing has an overflow opening at an outlet of the inlet housing, wherein the overflow opening conveys the fluid to be purified to the filter element. The inlet housing has an inlet channel disposed between the inflow opening and the overflow opening. The inlet channel has an intermediately positioned channel section located between the inflow opening and the overflow opening, wherein a cross-sectional shape of the intermediately positioned channel section differs from a cross-sectional shape of the inflow opening and from a cross-sectional shape of the overflow opening.Type: GrantFiled: July 22, 2020Date of Patent: October 18, 2022Assignee: MANN+HUMMEL GmbHInventors: Mario Rieger, Pedro Miguel Pereira Madeira, Stefan Kunze, Ulrich Dehnen, Johannes Stuerner, Markus Beylich

Patent number: 11338235Abstract: A filter device is provided with a filter housing provided with a housing wall and with a filter element arranged in the filter housing. The filter element has an annular filter medium body and an end disk arranged at an end face of the filter medium body. The filter medium body surrounds in a ring shape an inwardly positioned flow space for receiving a fluid to be filtered. An annular circumferentially extending flow path is positioned between an outer contour of the end disk and an inner side of the housing wall of the filter housing. Guide vanes project into the annular circumferentially extending flow path. The guide vanes are fastened at the end disk at the filter element. A cover is arranged at the end disk at the filter element and covers a portion of the annular circumferentially extending flow path.Type: GrantFiled: July 22, 2020Date of Patent: May 24, 2022Assignee: MANN+HUMMEL GmbHInventors: Mario Rieger, Pedro Miguel Pereira Madeira, Stefan Kunze, Ulrich Dehnen, Johannes Stuerner, Markus Beylich

Patent number: 11219855Abstract: A filter module is provided with a filter housing provided with an inflow opening. A filter element with an annular filter medium body with an elongate cross-sectional shape is arranged inside the filter housing. A flow path is defined between the inflow opening of the filter housing and an inflow side of the filter medium body. A swirl device is arranged in the flow path and impresses a swirl onto an incoming fluid. The swirl device is a part separate from an outer wall of the filter housing. The swirl device is arranged axially upstream of the inflow side of the filter medium body. The swirl device is provided with a displacement body arranged inside the filter housing adjacent to the inflow opening. The displacement body forms a flow guiding element.Type: GrantFiled: July 22, 2020Date of Patent: January 11, 2022Assignee: MANN+HUMMEL GmbHInventors: Mario Rieger, Pedro Miguel Pereira Madeira, Stefan Kunze, Ulrich Dehnen, Johannes Stuerner, Markus Beylich

Patent number: 8919492Abstract: An adsorption unit for combustion gas of an internal combustion engine has an adsorption housing having a chamber section with an inner wall. An adsorption element disposed in the adsorption housing is made of a gas-permeable adsorption medium that is formed to a hollow body and encloses an interior of the adsorption element. The hollow body has opposed open ends. A main flow passage extends through the hollow body and the combustion gas flows in main flow direction through the hollow body. The adsorption element has an exterior circumferential side facing away from the interior and delimiting together with the inner wall of the chamber section a bypass chamber surrounding the absorption element outwardly. In the main flow direction, the bypass chamber has a downstream end that is closed off and an upstream end that has at least one bypass opening that communicates with the main flow passage.Type: GrantFiled: June 6, 2012Date of Patent: December 30, 2014Assignee: Mann+Hummel GmbHInventors: Michael Metzger, Calogero Colletto, Johannes Stuerner, Armin Ludmann
