Publication number: 20240079614Abstract: A control flap assembly for a gas flow in a fuel cell system, in particular in a vehicle, includes a control flap housing providing a gas flow channel, and a control flap with a disk-like control flap body which can be adjusted in the control flap housing between a closed position preventing a gas flow through the gas flow channel and at least one open position opening up the gas flow channel for a throughflow. A control flap seat is provided on the control flap housing, and a sealing region bearing against the control flap seat in the closed position of the control flap is provided on the control flap. The sealing region includes resilient sealing material on an external peripheral region of the control flap body.Type: ApplicationFiled: August 31, 2023Publication date: March 7, 2024Inventors: Markus Lory, Matthias Grün, Andreas Wacker, Jochen Hammer, Markus Birgler, Annika Zeumer

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: 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
