Publication number: 20210002874Abstract: The disclosure relates to a conduit connector for a fluid line, having a housing, which has at least one first connection geometry and one second connection geometry, each for connecting to a fluid line. In the housing, a fluid-conducting channel is formed between the first connection geometry and the second connection geometry. In order to avoid damage due to freezing of a liquid located in the channel or the connected fluid lines, the housing has a volume equalization device, which is connected to the channel.Type: ApplicationFiled: February 11, 2019Publication date: January 7, 2021Inventor: Thomas Petschl

Patent number: 10490993Abstract: A wind-protection casing includes a plastic shell having a first partial shell and a second partial shell, wherein the first partial shell and the second partial shell surround an accommodating space and form a first and second line opening, which connect the accommodating space with the surrounding region outside the accommodating space. A retaining means is provided with an accommodating geometry for a line plug connector, which is arranged on the first partial shell and is designed in such a way that a line plug connector accommodated by the accommodating geometry is retained in the accommodating space at a distance from the first partial shell and the second partial shell via an air gap. A plug-connector device including such a wind-protection casing of this type is also provided, wherein a line plug connector is accommodated in the accommodating geometry.Type: GrantFiled: May 17, 2016Date of Patent: November 26, 2019Assignee: NORMA Germany GmbHInventors: Viktor Stoll, Stephan Mann, Benjamin Weber, Thomas Petschl

Patent number: 10295097Abstract: A coupling connection device includes a line coupling connector and a wind guard. The line coupling connector has first and second coupling elements, fitted together in an axial direction. Arresting means of the first coupling element engage with the second coupling element. The wind guard has a plastic shell with a first part-shell and a second part-shell, enclosing a receiving space, and forming first and second line openings, which connect the receiving space to the surrounding region. The first coupling element is coupled in an axially fixed manner in the axial direction to the first part-shell and/or the second part-shell in the receiving space by interlocking engagement. By a movement of the wind guard in the axial direction and away from the second coupling element, an arresting means can be actuated and the first coupling element can be separated from the second coupling element.Type: GrantFiled: May 24, 2016Date of Patent: May 21, 2019Assignee: NORMA Germany GmbHInventors: Benjamin Weber, Viktor Stoll, Thomas Petschl, Stephan Mann

Patent number: 8501002Abstract: The invention concerns a filter insert (1) that is provided as an exchangeable insert in a filter, in particular an oil filter, fuel filter or the like of an internal combustion engine. The filter comprises a filter housing (3) that can be separated along a separating plane (2) and the exchangeable filter insert (1) extending in an axial direction (18). Two housing parts (4, 5) of the filter housing (3) are sealed relative to one another along the separating plane (2) by means of a seal (6). The seal (6) is secured slidably and captively in the axial direction (18) on the filter insert (1).Type: GrantFiled: November 29, 2007Date of Patent: August 6, 2013Assignee: Mann + Hummel GmbHInventors: Kai Knickmann, Ralf Blum, Wolfgang Cedzich, Andreas Franz, Roland Hartmann, Herbert Jainek, Gunnar-Marcel Klein, Markus Kolczyk, Thomas Petschl, Steffen Ritter, Mathias Schuster, Birgit Herbst, Ralf Kaiser, Uwe Kaiser, Joachim Kegel, Hans-Günter Wächter

Patent number: 8303679Abstract: A filter closure system has a connecting head with a connecting web and further has a connecting end at an end face of a filter housing. The connecting head and the connecting end are matched to one another. The connecting end is pushed onto the connecting head in a mounting direction into a mounted state on the connecting head so as provide a seal-tight connection in the mounted state. The connecting end and the connecting web that extends in the mounting direction are provided with a micro toothing. When pushing the connecting end onto the connecting head in the mounting direction, the micro toothing connects by positive locking action the connecting end and connecting head with one another. The engagement of the micro toothing between connecting end and connecting head is realized along a flank of connecting web and connecting end which flank extends in the mounting direction.Type: GrantFiled: March 27, 2009Date of Patent: November 6, 2012Assignee: Mann + Hummel GmbHInventors: Karlheinz Muenkel, Ralf Bauder, Raphaelle Brast, Steffen Ritter, Michael Thienel, Carsten Schippers, Thomas Petschl

Patent number: 8105485Abstract: A filtering device for filtering liquids in internal combustion engines has a filter housing and a filter element inserted into the filter housing. A cover disk closes off the filter housing. The cover disk consists of two individual disks and a central flow connection connects the two individual disks. The two individual disks and the flow connection form a common plastic component.Type: GrantFiled: May 12, 2006Date of Patent: January 31, 2012Assignee: Mann+Hummel GmbHInventors: Markus Kolczyk, Dieter Amesöder, Sven Epli, Michael Thienel, Michael Wein, Luiz Carlos Fritz, Dieter Schreckenberger, Marco Woitoll, Thomas Petschl, Matthias Teschner

Publication number: 20100059427Abstract: A filtering system has a filter housing and a filter element and having a raw side and a clean side arranged in the filter housing. Liquid introduced into the filter housing flows through the filter element from the raw side to the clean side. An overflow valve is disposed between the raw side and the clean side of the filter element. The overflow valve is moved into an open position should a pressure of the liquid on the raw side of the filter element surpass a limit value. The overflow valve has an adjustable valve body loaded by a valve spring and made from plastic material. The filter element and of the filter housing structurally supplement one another such that the filter element is positioned precisely in the filter housing and relative rotation of the filter element relative to the filter housing is prevented.Type: ApplicationFiled: August 23, 2009Publication date: March 11, 2010Applicant: MANN+HUMMEL GmbHInventors: Thomas Petschl, Luiz Carlos Fritz

Publication number: 20090242470Abstract: A filter closure system has a connecting end at an end face of a cylindrical filter housing and a connecting head matching the connecting end. The connecting end is insertable axially into the connecting head and connected positive-lockingly to the connecting head by an insertion-rotation movement. Connecting end and connecting head have a bayonet connection with receiving slots or receiving projections and matching insertion projections. The matching insertion projections engage the receiving slots or projections when the bayonet connection is closed. The receiving slots or projections and the insertion projections each are arranged substantially in a perpendicular plane relative to the insertion direction. The receiving slots or projections are elongate and circumferentially do not extend completely around but are segmented. The receiving slots or projections are sequentially arranged in the insertion direction and are substantially parallel to one another.Type: ApplicationFiled: March 27, 2009Publication date: October 1, 2009Applicant: MANN+HUMMEL GMBHInventors: Karlheinz Muenkel, Klemens Dworatzek, Thomas Petschl, Stefan Becker, Duc Cuong Nguyen
