Patent number: 11285407Abstract: A liquid cleaning element has a cleaning medium and a carrier medium connected to each other. The carrier medium is provided with a liquid connector to connect to a line for liquid to be cleaned or cleaned liquid. The liquid cleaning element has a bend in a section provided with the cleaning medium and the carrier medium. The carrier medium, prior to connection to the cleaning medium, is pre-manufactured in a final shape of the liquid cleaning element. The liquid connector has a cylindrical suction socket and is arranged at or integrated in the carrier medium. A liquid cleaning system is provided with the liquid cleaning element and a holder holding the liquid cleaning element. In a method for producing the liquid cleaning element, the carrier medium is pre-manufactured in a final shape of the liquid cleaning element and the cleaning medium is connected to the pre-manufactured carrier medium.Type: GrantFiled: April 23, 2019Date of Patent: March 29, 2022Assignee: MANN+HUMMEL GmbHInventors: Pascal Egger, Heiko Wyhler, Alois Maier, Norbert Strassenberger

Publication number: 20200217275Abstract: A filter medium is provided with a first layer as a support layer and a second layer as a filtration layer arranged downstream of the first layer. The first layer and the second layer both are provided with at least one active agent that is at least antibacterial. The active agent can be applied as a coating or as an impregnation. Examples of active agents are pyrithione, a metal salt of pyrithione, a pyrithione derivative, a metal salt of a pyrithione derivative, and a quaternary ammonium salt. A filter element is provided with such a filter medium in the form of a filter media pack. The filter medium and filter element can be used in a water injection system for internal combustion engines.Type: ApplicationFiled: January 6, 2020Publication date: July 9, 2020Inventors: Jochen Krauss, Christine Oprisch, Heiko Wyhler

Patent number: 10343091Abstract: A filter element has a filter material defining a raw side and a clean side of the filter element and to be flowed through by a medium to be filtered from the raw side to the clean side. A non-return element is disposed on the filter material. The non-return element allows a return flow of the filtered medium from the clean side back to the raw side and prevents a flow of the unfiltered medium from the raw side to the clean side. A filter and a filter system with such a filter element are disclosed. The filter system has a pump to supply medium to be filtered to the filter.Type: GrantFiled: March 23, 2017Date of Patent: July 9, 2019Assignee: MANN+HUMMEL GmbHInventors: Norbert Strassenberger, Kathrin Tschepe, Heiko Wyhler, Christian Kocksch, Christopher Banks, Martin Postel, Christian Thalmann, Frank Pflueger, Christine Oprisch

Publication number: 20190176069Abstract: A filter element of a filter for filtering fluid has a multilayer filter medium through which the fluid flows in a flow direction from an inflow side to an outflow side of the filter medium for filtration. The filter medium has several layers including at least one filtration layer and at least one support layer. The at least one support layer supports the filter medium against pressures having pressure gradients transverse or oblique to the flow direction of the fluid through the filter medium.Type: ApplicationFiled: December 6, 2018Publication date: June 13, 2019Inventor: Heiko Wyhler

Patent number: 9895637Abstract: A filter medium of a filter element for filtering a fluid has at least one nonwoven filter layer of synthetic individual fibers. The filter layer has an increasing level of compression in a flow direction of a fluid passing through the filter medium. The filter medium has a degree of separation for particles to be filtered that increases in the flow direction of the fluid through the filter medium. The filter medium is used in a filter element for filtering fluids such as fuel or air. In a method for producing the filter medium, the synthetic fibers are deposited on a support surface in such a way that an increasing level of compression is created in a direction toward the support surface by gravity and suction acting on the fibers.Type: GrantFiled: September 12, 2012Date of Patent: February 20, 2018Assignee: MANN+HUMMEL GmbHInventors: Sebastian Neubauer, Jochen Reyinger, Heiko Wyhler

Patent number: 8584868Abstract: A filter medium for removing particles from a fluid flow has a pre-filter layer and a fine-filter layer joined to each other in the flow direction. A first supporting layer is attached to the unfiltered side of the pre-filter layer and a second supporting layer is attached to the filtered side of the fine-filter layer in order to absorb the longitudinal and transverse forces in the event of tensile loading. The traverse force absorbing layer has a greater bending stiffness in a traverse direction while the longitudinal force absorbing layer has a greater bending stiffness in a longitudinal direction.Type: GrantFiled: September 17, 2011Date of Patent: November 19, 2013Assignee: Mann+Hummel GmbHInventors: Heiko Wyhler, Jochen Reyinger, Klaus Gehwolf
