Patent number: 11648491Abstract: A filter device is disclosed. The filter device includes a coalesce and a final separator arranged one after another in a flow direction. The final separator includes final separator material and is arranged radially within the coalesce. The coalesce is configured hollow-cylindrical and includes a coalescer material and an external support structure with an upper coalescer ring and a lower coalescer ring that are connected with one another via axial coalescer ribs. A positioning element is provided on the final separator. A positioning opening is provided in a region of the at least one lower coalescer ring. The positioning opening is configured in a complementary manner to the positioning element and the final separator engages into the positioning opening in a mounted state with the positioning element and thereby aligns the final separator relative to the coalesce.Type: GrantFiled: October 14, 2020Date of Patent: May 16, 2023Inventors: Heiko Hensinger, Peter Koppi, Maria Kraut

Publication number: 20200386198Abstract: A fuel filter device for an internal combustion engine may include a water separator through which a fuel is flowable. To separate water contained in the fuel, the water separator may include a porous and hydrophilic membrane, which may include or be made of polymeric hollow fibers and which may be formed for cross-flow filtration of the fuel. A material of the hollow fibers may be hydrophilized via polyvinylpyrrolidone (PVP). The fuel filter device or the water separator may have a hydrophobic membrane for filtering residual fuel from the water separated via the hydrophilic membrane.Type: ApplicationFiled: October 1, 2017Publication date: December 10, 2020Inventors: Martin Hein, Peter Koppi, Maria Kraut, Markus Preissinger, Julia Santer

Publication number: 20200070075Abstract: A filter medium for fuels may include a first layer of a filter material and a second layer of a filter material. A contact angle of water on the first layer of filter material may be greater than 90°. A contact angle of water on the second layer of filter material may be greater than 90°. The first layer of filter material may have an average pore diameter that is greater than an average pore diameter of the second layer of filter material.Type: ApplicationFiled: August 30, 2019Publication date: March 5, 2020Inventors: Peter Koppi, Maria Kraut, Julia Santer, Wolfgang Zupanc

Patent number: 10569205Abstract: A separator for a separator device, for example a final separator for a final separator device for separating water from a liquid such as oil and/or fuel, may include a filter body including at least one filter material through which the liquid can flow. The filter body may have a first side and a second side. A nanofibre layer may be disposed on the first side in at least one region. The nanofibre layer may be configured hydrophobic. According to an implementation, the nanofibre layer is treated to produce the hydrophobic property. The filter body may have a porosity on the first side that is smaller than on the second side.Type: GrantFiled: August 26, 2015Date of Patent: February 25, 2020Assignee: Mahle International GmbHInventors: Birgit Renz, Peter Koppi, Mathias Kollmann, Julia Santer

Patent number: 10221820Abstract: A fuel supply system for an internal combustion engine may include a water separator configured to separate a polar phase, for example water, out of fuel. The water separator may be arranged at least one of on and in a fuel supply system component. The water separator may be configured as an electric coalescer. The electric coalescer may have at least two electrodes that are insulated from the fuel.Type: GrantFiled: September 10, 2014Date of Patent: March 5, 2019Assignee: Mahle International GmbHInventors: Peter Koppi, Maria Kraut, Hans-Peter Lang

Publication number: 20180272261Abstract: A filter medium may include a hydrophilic filter layer that permits through-flow from an unfiltered side towards a clean side and a hydrophobic layer disposed on the clean side of the hydrophilic filter layer. The hydrophilic filter layer may have a pore diameter that increases in the through-flow direction. The hydrophobic layer may take the form of a film layer.Type: ApplicationFiled: September 12, 2016Publication date: September 27, 2018Inventors: Mathias KOLLMANN, Peter KOPPI, Birgit RENZ, Julia TSCHISCHE
