Publication number: 20240003472Abstract: A device has a flange including a base body with a main contact face and a further flange including a further base body with a further main contact face. In a mounted state the flange is connected to the further flange with a sealing element therebetween. The flange has a recess which adjoins the main contact face and in which the sealing element is arranged. The further flange has an extension which protrudes from the further base body at the further main contact face and engages in the recess and contacts the sealing element. The extension positions and centers the sealing element and/or compresses the sealing element. The flange and the further flange jointly delimit a groove which forms part of the recess and partially receives the sealing element, and a groove width increases from an opening of the groove to a low point of the groove.Type: ApplicationFiled: June 30, 2023Publication date: January 4, 2024Inventors: Markus H. GERICKE, Frank LAUER, Reto SCHAFFNER
