Patent number: 11603803Abstract: A coupling arrangement is disclosed for the rotational coupling of a drive element of a pivoting drive of an exhaust-gas flap for the exhaust-gas flow of a combustion engine to a pivot shaft rotatable about a pivot axis. A first coupling element has a coupling region coupled to a pivot shaft for rotation about the pivot axis. A preload element generates a force acting on the first coupling element and the second coupling element in a peripheral direction with respect to one another and generates a force acting in an axial direction between the coupling elements. One of the coupling elements includes two radially outwardly extending rotational coupling projections and the other coupling element includes a rotational coupling cutout receiving the projection. The one coupling element is held axially on the other coupling element by the preload element to prevent the projections from moving out of the cutouts.Type: GrantFiled: January 19, 2022Date of Patent: March 14, 2023Assignee: Purem GmbHInventors: Matthias Grün, Markus Birgler, Markus Lory, Andreas Wacker, Annika Zeumer, Ralph Schenk, Miljenko Novosel

Patent number: 11578671Abstract: An exhaust-gas flap device, including for the exhaust-gas flow of an internal combustion engine, has a flap pipe and a flap plate that is supported in the interior of the flap pipe on a pivot shaft. The pivot shaft is rotatable about a pivot axis (A). The pivot shaft has first and second axial end regions and is supported rotatably on the flap pipe by respective first and second bearing assemblies. The pivot shaft is configured, in the first axial end region, for coupling to a drive element of a pivot drive. The pivot shaft is, in at least one of the axial end regions, in contact with vibration-damping material that is supported relative to the flap pipe.Type: GrantFiled: July 13, 2021Date of Patent: February 14, 2023Assignee: Purem GmbHInventors: Matthias Grün, Markus Birgler, Markus Lory, Andreas Wacker, Annika Zeumer, Ralph Schenk, Miljenko Novosel

Patent number: 11572842Abstract: A coupling arrangement is disclosed for rotationally coupling a drive element of a pivoting drive of an exhaust-gas flap for the exhaust-gas flow to a pivot shaft that is rotatable about a pivot axis. A first coupling element has a coupling region coupled to the pivot shaft for conjoint rotation about the pivot axis and a second coupling element has a coupling region coupled to the drive element for conjoint rotation about the pivot axis. A preload element acts on the first coupling element and the second coupling element substantially in a peripheral direction with respect to one another. One of the coupling elements has two rotational coupling projections which extend radially outward with respect to the coupling region of the coupling element. The other coupling element includes, so as to be assigned to each rotational coupling projection, a rotational coupling cutout which receives the corresponding rotational coupling projection.Type: GrantFiled: January 19, 2022Date of Patent: February 7, 2023Assignee: Purem GmbHInventors: Matthias Grün, Markus Birgler, Markus Lory, Andreas Wacker, Annika Zeumer, Ralph Schenk, Miljenko Novosel

Patent number: 11466629Abstract: An exhaust-gas flap device, especially for the exhaust-gas flow of an internal combustion engine, has a flap pipe and a flap plate that is supported, in the interior of the flap pipe, on a pivot shaft that is rotatable about a pivot axis. The exhaust-gas flap device further includes a pivoting drive for the pivot shaft with a drive element. A coupling unit couples the drive element to the pivot shaft for conjoint rotation about the pivot axis. Vibration-damping material is arranged in the region of the coupling unit.Type: GrantFiled: July 13, 2021Date of Patent: October 11, 2022Assignee: Purem GmbHInventors: Markus Lory, Markus Birgler, Matthias Grün, Andreas Wacker, Annika Zeumer, Ralph Schenk, Miljenko Novosel
