The invention relates to a method for producing at least one gear, in particular a helically toothed gear, wherein the gear is produced from a gear blank pressed and sintered with an oversize in the region of the set of teeth, wherein the gear blank has two opposite end faces and a circumference. In the method, the gear blank is clamped in a clamping means. The gear blank is compressed in the region of the oversize by means of the engagement of at least one circumferential tool having a set of mating teeth that engages with the set of teeth of the gear blank, wherein the gear blank is radially clamped over the circumference by the clamping means at both end faces during the compression of the gear blank, wherein each individual tooth of the set of teeth of the gear blank is supported by the clamping means substantially over the entire tooth height. In this way, the quality of the set of teeth can be improved. The invention further relates to a device and to a clamping means.

A valve component includes a first disk-shaped joining part and a second disk-shaped joining part. The first disk-shaped joining part has a first opening and has an elevation in a first region of the first disk-shaped joining part which runs at least partially peripherially around the first opening. The second disk-shaped joining part is joined to the first disk-shaped joining part and has a second opening which together with the first opening defines a channel for flow of a fluid medium therethrough. The second disk-shaped joining part further has a depression in a second region of the second disk-shaped joining part which runs at least partially peripherially around the second opening and which opposes the first region of the first disk-shaped joining part. The elevation interacts with the depression in sealing fashion.
