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 peripherally 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 peripherally 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.

Production of multi-part, joined valve components in hydraulic applications with joint sealing profiles

The invention relates to a valve component, in particular for a piston or a valve, comprising at least one first disk-shaped joining part and at least one second disk-shaped joining part, wherein the first and second joining part each have at least one opening, and wherein once the joining parts have been joined, the opening in the joining parts interacts in such a way that a channel is formed and a fluid medium can flow through the channel. In first and second regions at the joining parts, an at least partially peripheral elevation and/or depression interact with one another in sealing fashion once joined.

The invention relates to a piston for a piston-cylinder arrangement, particularly a shock absorber piston, which includes a piston body, that has a circumferential surface. A sealing collar has an outer circumferential surface, an inner circumferential surface, a first peripheral surface, and a first sealing lip, and extends around the circumferential surface of the piston body and covers at least part of the circumferential surface in the axial direction. The first peripheral surface connects the two circumferential surfaces to each other at a first end of the sealing collar. The first sealing lip is delimited by the first peripheral surface and the outer circumferential surface, and the first sealing lip is configured evenly in the circumferential direction.
